MadAppGang is a team of tech experts specialising in mobile technologies. We develop applications for iOS, Android, WatchOS, MacOS, tvOS, Android Wear, wearables, and provide IoT system integration services.

 

Our experience with mobile apps, artificial intelligence and embedded systems provides a uniquely powerful resource for our clients.

 

We work with established businesses and startups who are seeking to innovate and improve customer experience. Over the past few years we've built solutions for fintech, healthcare, fitness, transportation, and communication industries.

 

We speak the language of both software and hardware (and we can still talk to real people). We're well-versed in security, real time systems, and machine learning. But what's even more important, we can explain a compression algorithm to a child.  

 

We replace time-worn tools and methods with new technologies and innovative processes.

We choose technologies and tools that make our development process fast, help us create better apps, and can be easily supported after the product is launched. Our core tech stack includes Swift, Kotlin, Golang and React – something that was invented less than a decade ago.

 

We love mobile because it's powerful, useful and it's in everybody's pocket. Though the real reason is – we have fun building stuff for mobile.

 

We've been at this for almost five years. And we're still excited to move tasks to a current sprint's board.

Feedback summary: 

The solution was completed in just eight weeks. MadApp Gang managed the project seamlessly and built the foundation for their customer’s success.

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 CEO and founder of a medical startup. We accelerate clinical trial recruitment by connecting researchers, physicians, and patients to trials automatically.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with MadAppGang?

We needed development work done quickly as part of an accelerated program. We wanted to get an initial proof-of-concept out to market and solidify the scope of our project.

SOLUTION

What was the scope of their involvement?

MadAppGang built a search engine for people to look for clinical trials in their area. They used AWS, AWS comprehend and AWS comprehend medical. After viewing some of my initial sketches they created the frontend and backend of our platform. They also created a landing page for our website. They only had 8-10 weeks to develop this project. We wanted something that was user-friendly, had the right amount of data, and had an overall optimized view for the patient-facing side.

What is the team composition?

I worked with Jack (CEO, MadAppGang) and at least four other team members.

How did you come to work with MadAppGang?

I was referred to MadAppGang by a colleague.

How much have you invested with them?

We’ve invested $24,000 AUD (approximately $17,000 USD).

What is the status of this engagement?

This project spanned from March – May 2019.

RESULTS & FEEDBACK

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

We launched our business as a direct result of their work. We now have a brand, an initial lead-generation flow, and basic infrastructure in place.  

How did MadAppGang perform from a project management standpoint?

MadAppGang was excellent in terms of project management. They worked seamlessly, and I had access to everything. We engaged in a daily standup where all my questions were answered. We used Slack and Zoom for communication.

What did you find most impressive about them?

I found their project management to be most impressive. They were flexible, in terms of working around my schedule, and were able to prioritize tasks well. The team was highly communicative and resolved any issues quickly.

Are there any areas they could improve?

It would be nice to have a post-deliverable wrap-up session. We had an informal one, but it’s an area that could be refined better next time.

Do you have any advice for potential customers?

I think it’s important for a client to know the scope of their project well, so that development is as seamless as possible. It’s always best to give more information than necessary up front so that the project doesn’t slow down.

BACKGROUND

Introduce your business and what you do there. 

I'm the president of the WUW Technologies Inc.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with MadAppGang?

We needed a partner for our Creative Connect project, which is a mobile app platform that connects artists with clients.

SOLUTION

What was the scope of their involvement? 

MadAppGang built the iOS platform using Swift as well as AWS AppSync on the backend. They played an extensive role in the development process. We came to them with the vision and the designs ready to go, and they made the app functional. 

The platform features an idea solution form built into the app where users can submit ideas. Artists scroll through to decide if they want to create the ideas or not. The user can also search by scrolling the artists feed to find someone to create their idea. 

What is the team composition?

Jack (CEO & developer, MadAppGang) is our main point of contact. He had about seven developers working on our project.

How did you come to work with MadAppGang?

I found them just by browsing online. We did a video call with Jack and decided to go with MadAppGang.

How much have you invested with them? 

We’ve spent $115,000.

What is the status of this engagement? 

Work began in October 2018, and they had the product ready by March 2019. The engagement is ongoing as we're still improving the app.

RESULTS & FEEDBACK

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

MadAppGang delivered a working app. It does exactly what we intended it to do. We've been getting a lot of great feedback. The app currently has a five-star rating on the App Store. 

How did MadAppGang perform from a project management standpoint? 

Jack is a tremendous developer and the whole team is very professional. We communicate by phone, email, and video calls. They respond quickly and always do their best to help.

What did you find most impressive about them? 

They understood our concept quite well and were able to bring it to life. MadAppGang is a partner we can go to with a big idea and know that they'll make it happen. 

Are there any areas they could improve? 

They did a great job overall but certain things can always be better. We’d like to improve the backend so it’s faster and more reliable.

Do you have any advice for potential customers? 

Before you start the project, dive deeper into areas of the app where you need to really pay attention to the design. There are sections of our app where it scrolls and there's no data so maybe we need an extra button. You need to guide your audience and make sure each page has the right details. That's your responsibility as the person who's coming up with the idea.

Their products are consistently stable, well-tested, and free of major bugs. Everyone on their team has strong skills and they integrate well with in-house staff. Project management is thorough and well-documented.

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 CEO of a food ordering company. We provide an app that lets users order ahead at restaurants and bars.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with MadAppGang?

We started out with an in-house tech team but started seeing lots of bugs in our software, so we decided to hire an outside team to repair it.

SOLUTION

What was the scope of their involvement?

After going through our code and identifying the bugs, they redeveloped our software from the ground up and provided a scalable infrastructure for us. Our original site had been built somewhat poorly using PHP but they’ve redone it using GoLang and built a sophisticated admin panel using React JS. We run on AWS and we also use one of their tools for reporting, with integrations for Google Drive. On top of that, they developed native Android and iOS apps for us, with a payment system set up through Stripe. They’re also currently working on a web app to go with the mobile ones, which is being built with React JS.

Generally speaking, they develop projects almost entirely from scratch. Sometimes we’ll give them designs in advance, but they’ll often have to collaborate with our UI/UX designer to build from the ground up.

What is the team composition?

Our main point of contact is their CEO, Jack Rudenko. We have a developer team that averages between eight and 16, depending on what we’re building, but there have been times when we’ve had up to 30 people.

How did you come to work with MadAppGang?

We found them through Outreach. After interviewing several companies, we decided to go with them.

How much have you invested with them?

We’ve spent around $1.5 million to date.

What is the status of this engagement?

We started working with them in July or August of 2017 and the partnership is ongoing.

RESULTS & FEEDBACK

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

Partnering with them is like having an in-house development team. They’ve done a solid job of building out a scalable infrastructure and they’re flexible about adapting to our project needs. All of their products are tested thoroughly and stable upon release. There are only ever minor bugs.

How did MadAppGang perform from a project management standpoint?

They integrated really well with our team. We manage projects internally with Jira and their staff also uses Asana, so everything’s thoroughly covered. Their project manager is great at interfacing between non-technical staff and developers.

What did you find most impressive about them?

Their flexibility is one of their biggest strengths. They’re definitely top tier as far as coding skills because the company’s very strict about hiring developers who are familiar with cutting-edge languages, but their ability to adapt to changing circumstances and come up with creative solutions really sets them apart.

Are there any areas they could improve?

Not really. We’ve worked with them for a long time and they’re a core part of our team.

Do you have any advice for potential customers?

If you have the opportunity, hire them. Their CEO thinks on the large scale and has high standards for the company. They’re careful about quality as opposed to focusing on profits, which is refreshing.

Feedback summary: 

The application was developed efficiently, with early users beginning to use it after a successful testing period. The team managed the project smoothly, working in two-week sprints in a transparent and professional manner. They communicated effectively and produced a high-quality deliverable.

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 CEO of a logistics service provider.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with MadAppGang?

The challenge was building our entire application from scratch. We were working with a transportation company, and the development area was completely new to us. We were approached by that company to build the application. I was in charge of the project, but I didn't have any previous experience, so I needed someone to help me acquire that experience and build the application.

SOLUTION

What was the scope of their involvement?

They developed our Android application. It connects to a web interface, and its requirements also include an integration with the transportation company.


We set up the specifications and provided them to MadAppGang. We constantly updated the requirements during the work. They chose the best technologies themselves and kept me updated about crucial decisions, the APIs and other technologies, and so on.

The app's main users are drivers, who receive trip information from the logistics department of the company. Trip managers plan the trips and send them over to the drivers, who are then able to follow those trips and see all the destination points. The app sends out truck statuses: where they're being loaded and unloaded, whether they're waiting for a load, whether they're being serviced, and other information of this kind. These details are delivered back to the company's ERP.

What is the team composition?

The most crucial topics were discussed with Jack (Founder, MadAppGang). He had a team of people for tactical questions but remained our main point of contact.

How did you come to work with MadAppGang?

I found them through a reference as I did with the rest of my shortlist. I approached someone who used to work with MadAppGang and had had a positive experience. 


How much have you invested with them?

Above $100,000.

What is the status of this engagement?

The project was split into two parts. We built one application from October 2016–April 2017. We started work on the second one from August 2017–March 2018, on the foundation of the first.

RESULTS & FEEDBACK

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

The project is currently underway, and we're waiting to have more users on the app. We've just started to receive information from drivers.


There's been a testing period, during which we expected to see some bugs, but there was nothing unusual. Everything we identified was fixed, so we're satisfied with the level of quality.

How did MadAppGang perform from a project management standpoint?

Slack was our main communication tool. We try to stick to two-week sprints, and we've mostly been able to do it. If something unusual or unforeseen occurred, they took care of it on their own, and tried to compensate for any unplanned hours, bugs, or more difficult tasks. They delivered all the features we agreed upon and I was updated constantly.

What did you find most impressive about them?

Their professionalism. They know their stuff and they've been honest with me. If the client is new to the field, it's easy for a vendor to bill more hours, but MadAppGang is completely open and transparent. We've built a trusting relationship, and we almost always were able to find compromises on any issues. We kept a simple agreement; all questions or issues were settled through communication.

Are there any areas they could improve?

Probably, but there's nothing crucial; there are only minor incremental improvements like being more precise and focused. MadAppGang was pretty strong already, so they should just keep improving.

Do you have any advice for future clients of theirs?

Clients should draft clear specifications from the beginning, as far as possible. This will bring more clarity to their products and architectures. This is just general advice, not something related to our specific work with MadAppGang.

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 CEO and founder of WallBrand, a social shopping platform where users get paid to shop. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with MadAppGang?

Even though our app is relatively basic, developing it from scratch required a difficult, complex build.  We’d tried using remote developers from all over the world. After none of them could meet our requirements, we hired MadAppGang to take over. Specifically, we requested a beautiful, stable product that would function properly for the long term. 

SOLUTION

What was the scope of their involvement?

MadAppGang used Swift 3 and 4 for iOS to establish sound logic for our app. For the UI, they employed a combination of React and Swift. Each component they programmed is reusable. All the screens are entirely independent of users, which reduces the possibility for errors from iOS to the API. MadAppGang found a way to detect bugs without incurring significant consequences for the new framework. None of the developers we’d worked with before had been able to achieve this goal.

What is the team composition? 

My main point of contact is Jack (Founder, MadAppGang). 

How did you come to work with MadAppGang?

One of our in-house programmers been working with an iOS developer from MadAppGang and was impressed with his masterful technical skills. We considered trying to hire him directly but decided to partner with the whole team from a B2B perspective instead.

How much have you invested with them?

We spent about $100,000-$150,000.

What is the status of this engagement?

We’ve been working together since December 2016.

RESULTS & FEEDBACK

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

MadAppGang produced awesome work. I sent their soft code to be audited. Based on the results, we invested in a talented team that programmed a robust and reliable app for us.

How did MadAppGang perform from a project management standpoint?

Deciding on a strategy beforehand helped project management progress well. MadAppGang really did their part concerning the development. They produced satisfying work, so we didn’t have to check in on them often. Even though they worked remotely, we communicated effectively using Slack on a daily basis. Additional tools we used included ClickUp and Trello. 

What did you find most impressive about them?

I’ve worked with developers from all over the world, and MadAppGang is in the top 2%-3% I’ve ever seen. They can build an app at the same level of quality as major social media networks. It’s truly amazing. The team is kind, flexible, and really tries to understand our goals. They develop our products as if they were their own. 

Are there any areas they could improve?

MadAppGang could benefit from employing more people who speak different languages. They’ve communicated well with me in English but unfortunately couldn’t work with a French-speaking client I referred to them.

Do you have any advice for potential customers?

Take the time to share all the features you want and always explain your long-term view. Making sure they understand where you’re going will avoid any duplicated work or miscommunications.
