The system was launched successfully and received positive feedback from users. As a team, Coding Sans smoothly integrated themselves with an internal team and quickly adjusted to new methodologies.

BACKGROUND

Please describe your company and your position there.

I’m the VP of engineering for Emarsys, an independent marketing platform. I’m responsible for the quality and culture of our software development.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Coding Sans?

We were developing our Visual Content Editor product, a WYSIWYG editor to help clients create and design their campaigns. We needed development assistance to make the product compatible with multiple channels, including email and push notifications.

What were your goals for this project?

We needed to boost our internal development team. We wanted the project to strengthen the marketing campaigns our customers create. Ultimately, we were aiming to provide a seamless user experience.

SOLUTION

How did you select this vendor?

We followed a recommendation from a colleague, and they completed an in-office probation day.

Can you go into detail about the services they provided and the scope of the project?

Coding Sans worked alongside our in-house development team and participated in our agile meetings. They created code extensions and integrated them into our editor system. Their team created the plug-ins and applied our test-driven development (TDD) methodology. They used a range of programming languages, including JavaScript and TypeScript. They used Angular.js and React.js for the frontend and Node.js for the backend.

What was the team composition?

The size of their team fluctuated depending on our needs, but they typically provided over four engineers. They supplied both junior and senior developers.

RESULTS & FEEDBACK

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

We were able to release our WYSIWYG editor successfully, and our customers were satisfied with the results they experienced. We haven’t found any bugs in their coding.

How was project management arranged and how effective was it?

We handled all the project management tools, but their team adapted to our methods smoothly and flexibly. Coding Sans worked in our office with our in-house developers and attended the same meetings and planning sessions.

It'd be beneficial if they could provide more senior developers.

Feedback summary: 

Codings Sans addresses all bugs and issues in a timely manner. Their development process was quick and every deadline was met. From the success of the project so far, the partnership will continue after the launch of the product.

BACKGROUND

Introduce your business and what you do there.

I’m the founder of a small startup set to launch in mid-September. This is an EdTech (education technology) project.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Coding Sans?

I needed a team to develop an MVP version of my product.

SOLUTION

What was the scope of their involvement?

I provided Coding Sans with specifications and wireframes. After that, they developed the project from scratch. The product is a responsive web application that will work on both mobile and desktop. Coding Sans used Meteor and Angular to develop the application.

The platform allows developers to educate themselves about new technologies and new technology practices by watching videos created by other developers. My website is a special version of YouTube with only developer content. At this time, it could be fully launched, but I’m still working on the outreaching timeframe. For now, the app is still small. Coding Sans has handled everything on the product side and they created the project themselves.

What is the team dynamic?

There were 4 junior developers and 3 senior developers on the project. They provided me with a project manager who I had daily contact with.

How did you come to work with Coding Sans?

I used to work with the CEO of Coding Sans in the past. I reached out to him and told him about my idea, and he said he had the resources needed for my project.

How much have you invested with them?

Around $16,000.

What is the status of this engagement?

We started working together in May 2017 and the work is ongoing.

RESULTS & FEEDBACK

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

They have developed what I asked for. I was involved in the final phase when they finished the product; I found some bugs and some parts I wanted to modify, and they quickly did that. They fixed and modified everything as I asked for. Overall, the product is great.

How did Coding Sans perform from a project management standpoint?

It was really good. I used to work with different teams before this startup. With this project, I felt really involved. I was invited to their development team Slack channel, where I can see all of the conversations about the current issues they’re working on. I was talking to the project manager every day over the course of the project. Overall, it was a good experience.

What did you find most impressive about them?

They were really fast, which was the first thing that I noticed. After the kickoff meeting, it was only about two or three weeks before I saw a working application. For the scope of the project, it was completed very quickly. When we were working on the finalization, they were really fast with fixing and modifying any details I brought up.

Are there any areas they could improve?

It was a really short project, and we didn't have any issues.

Feedback summary: 

Since joining the team, Coding Sans has contributed to reliable product performance. Their consistent quality, adherence to all deadlines, and eagerness to improve their capabilities drive a productive engagement. 

BACKGROUND

Introduce your business and what you do there.

I’m the CEO of a video-messaging service partner startup founded in Hungary. We first partnered with Facebook and Kik Messenger and later introduced a chat bot. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Coding Sans?

We needed a live video edit from archived and YouTube footage as well. If somebody typed a text message and wanted to transport it to a video format, we have several ways to meet this need. Coding Sans helped us select and apply the right technology to make our vision possible.   

SOLUTION

What was the scope of their involvement?

We partnered with Coding Sans after our launch. We had some difficulties with expanding the business because we had much more volume than expected after partnering with Facebook. When they launched the new Facebook messenger, we were their first video partner. Coding Sans helped us find the right balance on the server side using Amazon Web Services.

Additionally, the backend of Node.js was a new format for our developers, and Coding Sans had experience using this platform for Android development. We have a few Android developers on our side, but they couldn’t solve issues related to live editing and synchronizing audio with the video.

How many resources have been assigned to your project?

There are at least 6 people involved in our project. I mainly keep in touch with Coding Sans’ CEO. We used a Scrum methodology and Slack for communication.

How did you come to work with Coding Sans?

They were recommended to us. We were desperate to find the right team, but in Hungary, it’s often hard to find the right talent for an IT job. After we came to the conclusion that we needed to hire a firm that can guarantee the level of quality that we expected, our CTO found Coding Sans. Ironically, they're located a mile away from our office, even though we searched for a provider for 2 years.

How much have you invested with Coding Sans?

We’ve spent $50,000 with them so far.

What is the status of this engagement?

We started working with them in December of 2015, and we are currently working on another project with them. I plan to use them in the future as well. 

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or impact of the engagement?

I really like working with them because of their guaranteed quality and respect for deadlines. If we find bugs, they take care of them quickly. They’ve never let us down, and I expect they’ll continue to meet our expectations in the future.

We measure how well our services are performed, but I’m not sure how to separate those statistics from all the other features that we developed ourselves. Our business depends on both the technology and the content. I think the technology was more important at the beginning but not anymore. Right now, the technology that we provide is the standard for our users, and the content is rather important for them.

How did Coding Sans perform from a project management standpoint?

Most importantly, they respected our deadlines. We trusted Coding Sans because they’re really keen on scheduling. Their project management was great. We had some communication issues at the beginning, but they were solved. At the beginning, they didn’t have project managers, which created some confusion, but that was resolved.

What did you find most impressive about Coding Sans?

They know what they’re talking about. They estimate accurately at the beginning and when we signed the contract. They also deliver 100%. If we ran into any deadline or development issues, they never overcharged us. They are really dependable.

Are there any areas Coding Sans could improve?

They still have some communication issues and could improve their project management. They’re working on doing better. They try to find the right project managers, but the lack of communication can create confusion.

Feedback summary: 

Although it was outside the initial scope, Coding Sans built solutions that dramatically reduced coding time and project costs. This demonstrated Coding Sans’ proactive and practical approach, which the client appreciated.

BACKGROUND

Introduce your business and what you do there.

We provide a Software-as-a-service product for getting publishers real-time analytics on product performance. I am the managing director of the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Coding Sans?

We had a platform rebuild carried out by an agency in the UK. It did not result in a fully completed product, so the Coding Sans team was brought in to finish the job.

SOLUTION

What was the scope of their involvement?

Coding Sans worked on our web-based app, which has a Python backend and a JavaScript React frontend. We have primarily worked with two people from Coding Sans’ team, including their CTO and a frontend developer. They built discrete features that were missing from our initial build. It was very much us directing Coding Sans in terms of the features that needed to be built, and what the specifications for them were. We worked on a time-and-materials basis. They performed some DevOps work as well. We were bringing clients onto the platform and had Coding Sans monitor our capacity usage and other factors.

The platform provides real-time analytics for article publishers. It’s a sort of web-scraper technology which pulls in a number of metrics from different sources, displays them in a ReactJS frontend, and serves email updates. Coding Sans built our email update functionality, providing a regularly scheduled service for each user. They did quite a lot of scalability and stability testing, helping us bring more clients on. The architecture up until that point hadn’t been particularly scalable.

Aside from these main functionalities, Coding Sans provided two or three hours of work at a time on small features that had been missing. They also corrected how certain metrics were being displayed. It was a range of data-gathering, email service, and scaling functionalities.

How did you come to work with Coding Sans?

They came through a personal recommendation from someone who had used the team at a previous company and knew some of the Coding Sans people individually. They were recommended as a cost-effective solution. We didn’t have the time for a proper procurement process, so we had an initial conversation, found out they had the skills we needed, and went ahead with Coding Sans.

How much have you invested with Coding Sans?

The cost of Coding Sans’ work has been £15,000. [$20,000]

What is the status of this engagement?

We started working with Coding Sans in February or March 2017. Everything has been completed, but I occasionally ask Coding Sans to help out with small tasks.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

The way in which our platform had been architected by the initial agency required that, whenever we brought in a new client, a new plug-in had to be written. The Coding Sans team wrote a generic plug-in that worked across 80% of new clients’ websites and required much less bespoke coding. This reduced the time for onboarding new clients from one to two days of coding to 30 minutes on average. This was a significant improvement, and, to be honest, Coding Sans didn’t have to do this. They could have simply offered to build a new plugin for every client and charge us each time. This is the main relevant metric.

How did Coding Sans perform from a project management standpoint?

Coding Sans’ CTO acted as our project manager. We used Slack for communication, with a dedicated channel for him, our developer, and their CEO. They were very responsive, letting us know when someone would be unavailable. It was clear whom we were dealing with.

What did you find most impressive about Coding Sans?

I haven’t dealt with many other agencies, but, compared to the ones I have used, Coding Sans is a pragmatic and outcome-focused group, rather than ideologically wedded to academically interesting ways of doing things. For an early-stage startup in particular, this was a good way of getting what we wanted. They have a can-do attitude, putting in long hours and charging us by the day, not by the hour. What Coding Sans did was pragmatic and focused on getting us the outcome we wanted.

Are there any areas Coding Sans could improve?

The prioritization of what they did could have been a bit better. On one instance, Coding Sans spent a bit of time on DevOps tasks that did need to be done in the long-term, but perhaps not immediately. I’m no DevOps expert, but I do have a reasonable technical understanding. My impression was that there were a couple of days spent on things that weren’t entirely necessary. But, in the grand scheme of things, this was minor compared to the good things done by Coding Sans.
