GuardRails Helps to Establish DevSecOps with Automated Security Reviews Image

GuardRails Helps to Establish DevSecOps with Automated Security Reviews

Mad Devs was involved with the Guardrails' security check service as a development contractor with exceptional knowledge of GitHub & GitLab processes.

GuardRails uses open source tools and libraries to check dependencies and detect security issues and vulnerabilities. It has 800+ software development teams using it officially on GitHub and is rapidly gaining popularity on GitLab. The number of

enterprise customers is also steadily increasing, especially since the release of an on-premise version of GuardRails.

As we at Mad Devs live and breathe automation and optimization, GuardRails was one of the most desired projects for our team to work on. Creation of powerful tools for developers means gaining more trust and respect in the community, so when we started to collaborate with client, our entire team was excited about the many cool things we could implement together.

GoDee is a start-up project that offers booking seats on a bus online.

GoDee Builds New Public Transport Habits in Vietnam. It re-invents public mobility by building a new and smarter way of a daily commute.Mad Devs started to consult GoDee at the early stage of this project assisting with the choice of the technology stack and step-by-step planning. Then a number of our positively mad developers started to work on the GoDee’s smart urban bus management system as a team.

The

project includes mobile applications for drivers (Android) and passengers (Android, iOS). A Django web panel is used for business purposes to create routes, get reports and show current active routes on a map. We have also added the predictor functionality that calculates estimated arrival time for a bus on this or that route. It helps our passengers check if the requested bus arrives on time, taking into account traffic jams. Referral programs are available to all passengers - everyone is eligible to get benefits for recommending GoDee to their friends. As cashless payments are becoming more and more popular in Vietnam, we have integrated Stripe service into GoDee enabling the passengers pay with credit cards easily and quickly. We have also developed an API for flawless third-party service integration. Depending on passengers’ requests, the system allows drivers to build the best possible routes automatically. If there are no orders from passengers, drivers will skip the empty bus stop along the way.

Teacherly: EdTech Platform for 70K Teachers

Our client is an educational technology company based in the UK. It offers a collaboration platform for teachers, the main purpose of which is to speed up lesson preparation thanks to templates. The project also enables lecturers and tutors to share their best practices with each other, and simplifies communications between teachers and students.

Mad Devs team stepped in to make the

Teacherly platform usability audit and rework the user journey to make it intuitive. After we created a walkthrough scenario for a teacher starting with the platform, re-created the UI and updated the React version from 14 to 16 to improve performance, the existing users got more engaged and started to recommend Teacherly to their colleagues.

 

This initial success resulted in a new contract with Teacherly, and now Mad Devs is a sole contact point for all tasks, including design, development, deployment, and support.

With their work, there was a notable return on investment as the order grew by 53% YoY. Mad Devs Team always surpasses expectations and is always open to suggestions. The team's competency and dedication enabled prolonged partnership between the company.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am a partner and director of shipping for NambaFood. Our platform has over 250 cafes and restaurants in town, shops, pharmacies and more.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mad Devs, and what were your goals?

We contacted Mad Devs regarding the development and support of software for delivery service. We wanted to create an intuitive tool for ordering food, goods, and more. As a result, the user was supposed to get a fast way to place an order with advantageous conditions and online payment. Adding a new counterparty should be easy for a manager, with sales numbers also available in real-time.

Operators and couriers were expected to instantly process the order. We also wanted to make it a solution for the faster launch of similar services in different countries of the world.

SOLUTION

How did you select this vendor and what were the deciding factors?

Mad Devs team was a very well known vendor of complex IT services in Central Asia. The team behind this brand included people who invested a lot of their personal time and effort into the development of IT expertise in this region. We witnessed the professional growth of Mad Devs and decided to partner with them.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

It was necessary to develop a service that would integrate:

  • a web site two applications for end-users (iOS and Android ones)
  • applications for couriers (the Android one)
  • administrative panel for managers to manage contractors (cafes & shops)
  • call center for a unified system for managing couriers

All this should come with technical support. Goals were identified, big tasks were discussed and split into smaller ones. Everyone involved with the project knew why this or that feature was needed.

We even documented the desired actions for the after launch phase. As a result, with each iteration, we got access to a solid, mature, and intuitive solution with a beautiful design, and most importantly, a user-friendly interface.

How many people from the vendor's team worked with you, and what were their positions?

During the launch and post-launch phases, the Mad Devs team working on the project was large. Сurrently we have a total of 5 people involved in the project as its maintainers. There's a project manager,  DevOps PHP developer, Android developer, and iOS developer.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

Thanks to our good relationships, Mad Devs’ professional execution of tasks, our leadership’s clear vision, and everyone’s focus on success, the number of orders in our project grows by 53% YoY.

Describe their project management style, including communication tools and timeliness.

We have daily stand-ups and weekly sprint closures. Every 15 days we receive a report for the previous period. We communicate via Jira, Slack, Telegram, Skype, GitHub, etc.

What did you find most impressive or unique about this company?

Mad Devs have extensive experience in various industries, which allows them to solve issues quickly and efficiently. They are constantly training their team members.

Are there any areas for improvement?

There's no limit to perfection. They know that, and so they're constantly improving.

We offer a top online restaurant reservation platform in South-East Asia founded in 2013. I was one of the first Product Managers in company and Product Owner of Billing System.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mad Devs?

We were working on building brand new version of platform including web, mobile and accounting. We've hired MadDevs to - build PWA (Progressive Web Application) for customer and merchant services - Billing System for accounting.

What were your goals for this project?

The goal for PWA was to be closely same convenient, easy to use and responsive as native mobile application. It includes all the functionality of desktop web or mobile app. The goal for Billing System was to provide one cross-country solution for custom accounting and report system.

SOLUTION

How did you select this vendor?

We've compared many studios taking into account the experience, a presence of big and complicated solutions in portfolio, reputation and price for sure.

Describe the project and the services they provided in detail.

As I had an expertise in software development - we've worked together on system architecture and technical solutions. We've started with the requirements analysis and guys dive deep into details. We've worked in a short iterations in agile mode, always staying tuned and synced up.

What was the team composition?

We've started with a few software developers whom I've managed directly and worked very close with as a project manager. We've involved more people when it's needed. There were backend and frontend engineers, some combine team lead roles.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The new Billing System allows to organize accounting across all 6 countries much better, reduce manual work and replace third party software with customizable in-house solution that being developed. PWA allows to reduce user acquisition cost and increase conversion rate for web users.

One small thing to improve is careful management and proper usage of junior developers by senior/team lead to avoid a situation when some task that done by junior could cost the same price as done by senior but took longer.

The Mad Devs team takes ownership of their projects, delivering top-notch work and offering alternatives that enhance the final product. Their reasonable pricing, consistent communication, and flexibility contribute to a rewarding collaboration.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I work for the world’s largest blockchain development and incubation company. We focus on R&D, application infrastructure solutions, and consulting. I am in charge of business strength and marketing for one of our subgroups.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mad Devs?

We had a lot of work to do and not enough people to do it. It was difficult to find people with skills in blockchain, especially smart contract, development, and security analysis tools.

SOLUTION

What was the scope of their involvement?

Our first collaboration was a workforce issue; we needed some people to do specific work. Mad Devs stepped in and helped us get several pieces of our project and product done. After that, we continued working with Mad Devs on specifications, development, and testing for the security modules of a hosted SaaS service. Some were in Python while others were in Solidity, which is specific to blockchain and Ethereum.  

We’re working on a big project that’s just about to launch. We’ve had a lot of milestones involving acquiring and building technology. They’re also integrating it into a platform that we’ve created.

What is the team composition?

Mad Devs lets us choose our resources. Initially, we chose one person from Mad Devs to work on one of our open-source projects. Afterward, they assigned 6–7 developers to another project that involved an audit security analysis engine and API.

How did you come to work with Mad Devs?

Since some of their members were already contributing to our open-source projects, we decided to reach out more formally based on the skill set they demonstrated on Ethereum. Their pricing was extremely reasonable, and they filled a gap we had.

How much have you invested with them?

So far, we’ve spent over $200,000 on their services. They charge an hourly rate and send quarterly statements of work.

What is the status of this engagement?

We started working with Mad Devs 12–15 months ago, and we’ve been collaborating ever since. 

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The Mad Devs team arrived and contributed immediately, helping us reach our milestones as we approached alpha and beta releases. We’re a remote team so we can pretty much choose to work with any developer on the planet, but we continue to work with Mad Devs. They are good at what they do.

How did Mad Devs perform from a project management standpoint?

It has been fantastic. Their communication is excellent. We collaborate using Discord servers and Slack, along with a bit of email. We had Trello boards for the project team, along with weekly and biweekly project status calls. Our projects are broken up into two-week sprints, and we test the work at the end of each one. We have a lot of flexibility.

What did you find most impressive about them?

Mad Devs went above and beyond what a typical contractor would deliver. Instead of giving us exactly what we asked for, they offered alternatives. They even mocked up prototypes, then implemented and tested them for us. They think about the product as though it is their own. Mad Devs quickly became an important part of our team, and they’ve remained that way. We don’t want to let them go.

Are there any areas they could improve?

Nothing comes to mind.  

Do you have any advice for future clients of theirs?

I can see a client going through a trial period to see which resource is the best fit, but we didn’t have to do that with Mad Devs. Certain individuals can be better matches for the technology or team in place, and Mad Devs is flexible in accommodating this.

I’m a co-founder of Namba Taxi. We’re an on-demand taxi service.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mad Devs?

We brought on Mad Devs to build our entire IT system (core IT engine, consumer and driver apps, and management information system).

What were your goals for this project?

We needed an entire technology system to run an on-demand taxi business.

SOLUTION

How did you select this vendor?

We appreciated Mad Devs’ entrepreneurial, flexible approach and ability to handle tight timeframes and budgets. Our interests were completely aligned.

Describe the project and the services they provided in detail.

They developed our entire infrastructure including iOS and Android applications for customers, Windows and Android driver applications, a backend system, and a dispatching module, which is a call center that accepts orders and coordinates with drivers. They built everything from scratch.

What was the team composition?

Initially, we worked with two developers—a lead engineer and another software engineer. The team has since grown to five people.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

Mad Devs’ software has allowed us to become a leading taxi company in our country. The various ways customers can order taxis (SMS, phone call, mobile app) has driven this growth. The most important result has been software stability during peak usage. 

What did you find most impressive about this company?

They work as if their own money and success are on the line. Their flexibility and continuous desire to improve stand out to us.

Are there any areas for improvement?

No, not that I’ve seen. They’re one of the best software development companies I’ve worked with.

Feedback summary: 

The resource provided by Mad Devs is excellent, bringing not only their own skill and expertise. but the input of the wider team to the project too. They manage the remote work seamlessly and fit well into the company’s workflow.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO at Veeqo, a platform for large e-commerce businesses. We automate their work and are a software as a service (SaaS) company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mad Devs?

We started with hosting our application on an infrastructure as a service which was quite expensive but allowed us to host our application without an in-house system administrator. However, it became too expensive, so we needed a system administrator or a dev op engineer to move to another hosting platform and start automating what we already have.

SOLUTION

What was the scope of their involvement?

They’ve been responsible for our entire infrastructure—everything running any application, code, or serving data was under their scope. They did anything from the database to application servers from caching to project management; from the main management to firewalls. The technology was defined by us. We use Amazon Web Services (AWS), Docker, and PostgreSQL.

What is the team composition?

The contract was for one dev ops engineer, but we get the expertise of the entire team. Even if the person we’re working with directly is stuck or lacks some knowledge, the entire team backs that person up.

How did you come to work with Mad Devs?

Finding an experienced, good quality dev op engineer is extremely difficult. We started to look for such people via agencies, while I also searched my network and some people recommended Mad Devs. They turned out to have an entire team of senior dev-ops engineers.

We were clear about what we needed, and Mad Devs made an offer with dev op. We met that person and agreed they were what we needed.

How much have you invested with them?

We spend thousands of dollars per month. It’s comparable with the monthly salary of a good dev ops engineer.

What is the status of this engagement?

We started working together in 2016 and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The dev op assigned to us was the perfect match. They were the best person we could ever dream of. It was exactly what we needed.

We’re very pleased with what we have now. Our infrastructure is much more resilient and secure, and we’ve improved automation. We’ve also managed to cut our expenses significantly.

How did Mad Devs perform from a project management standpoint?

Project management is great. We’re a remote first company, so we treat the dev op as if we hired them ourselves.

If our developers have any requests, they go straight to that person. I also regularly meet with them to check the plans and what has been done.

What did you find most impressive about them?

What stands out with them is the amount of talent they’ve managed to find and hire—it’s rare that one company has so much.

Are there any areas they could improve?

No.

Do you have any advice for potential customers?

Keep in mind you’re not only buying expertise of one person, but the expertise of the entire team that’s partnered with that person.
