BACKGROUND

Please describe your company and your position there.

I am the Executive Director of Mighty Plus, LLC - a Belarusian game development company creating interactive multi genre AR games using Unity technology. The company is based in Belarus, Minsk.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Jay.devs?

We needed software engineers specializing in game development using Unity3D technology to extend our team and fasten the development process of our AR game Wow Dog. Jay.devs offered us three skilled Unity developers to quickly integrate into our project.

What were your goals for this project?

We wanted to develop an engaging AR game for both iOS and Android users from scratch and to cover all the implemented functionality with manual tests.

SOLUTION

How did you select this vendor?

I had done some research on IT companies with Unity skills and found Jay.devs as the most organized, collaborative and relevant for our project. Moreover, they offered a convenient pricing and cooperation model for us.

Describe the project in detail.

Jay.devs developers helped us a lot in realizing a virtual Unity-based pet game from scratch. Among implemented functionality you can find:

  • Ability to take care of your pet (you can wash, feed, put to sleep and play with a beagle)
  • Ability to take part in exhibitions, competitions and earn coins
  • Different levels of complexity
  • Ability to spend earned coins on new updates
  • Wow Dog Selfie that allows its user to photograph the best moments of the game and share them with friends in social networks
  • Wow Dog Chat that allows user to communicate with the dog on any topics. Users can write different questions and receive funny answers sharing stickers, stories and compliments. Answers can be shared with friends.

All the implemented functionality has been covered by manual tests including functional (black box testing), localization and usability testing.

What was the team composition?

The engineering team consisted of three software developers. Production processes were organized by Mighty Plus, LLC

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Wow Dog was released in 2018 and published in Google Play and App Store. It has a 5.0 rating for gameplay and more than 100 downloads in Google Play. App Store users gave the game a 5.0 rating. After the game release, we started to receive more requests to create useful games like a study platform for elementary school students.

How effective was the workflow between your team and theirs?

Project management was fully organized from the Mighty Plus side. Being a project coordinator, I can definitely say that Jay.devs engineers are responsive, easy to collaborate and always deliver work on time. They solve issues coming mid-sprint proactively.

What did you find most impressive about this company?

Starting our cooperation, we quickly finished the paperwork, and Jay.devs engineers were ready to start. I was impressed by their code quality, responsiveness and easy-to-collaborate approach. Jay.devs team showed timely results, being effective through the whole development process.

Are there any areas for improvement?

While I know that there will always be areas for improvement in any organization, it is difficult to offer specifics on this. Jay.devs team discussed and corrected our concerns in a timely, friendly and very professional manner.

The Review
Feedback summary: 

Though quantitative results are not yet available, Jay.devs has contributed significant process value. Their ability to identify and circumvent potential roadblocks has resulted in steady development progress. Customers can expect regular updates and thorough, high-quality app testing.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the executive director of Technocrat, a software development agency for both enterprise and government sectors.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Jay.devs?

We needed a team of native iOS/Android engineers for a HealthTech client.

What were your goals for this project?

We set out to deliver the best mobile app experience possible for both patients and healthcare professionals.

SOLUTION

How did you select this vendor?

We interviewed and compared four similar companies. All delivered reasonably detailed and sound proposals, but Jay.devs's team was the most communicative, organized, and collaborative.

Describe the project in detail.

Jay.devs developed and tested native iOS and Android applications with features including patient registration, user creation, appointment search and booking, payment (integrated with Stripe), and appointment record management. Their testing regimen is comprehensive, involving cross-device and cross-platform tests, as well as manual, functional, and visual components.

One of the solutions was a “pro” or “partner” app for healthcare professionals. In addition to recording the medical details of the patient appointment, the app ingests images from medical imaging equipment and provides extensive calendar functionality (notifications of upcoming appointments, delays, and other changes).

What was the team composition?

We’re working with five software developers, a QA specialist, and a project manager.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We can’t disclose the results yet, but their project manager has been critical in identifying production problems and developing solutions.

How effective was the workflow between your team and theirs?

They’ve been proactive and communicative, and we’ve never had reason to question their commitment. All activities have been correctly planned and well-coordinated, leading to on-time deliveries.

What did you find most impressive about this company?

They’ve been consistently transparent about their progress and proactive about problems arising mid-sprint. They’re testing standards are excellent, and everyone we work with is communicative, responsible, and flexible. It’s obvious that Jay.devs’s leadership values and invests in their staff based on their hiring of a full-time English instructor to better serve international clients.

Are there any areas for improvement?

While there are always ways to improve, I can’t think of anything specific for Jay.devs. When we have issues, we discuss them, and they’re mediated quickly.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the CTO of EXADS, a software startup specializing in ad tech. We develop and maintain our own proprietary ad-serving technology platform and custom-built infrastructure.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Jay.devs?

We needed help to develop a cross-browser compatible HTML5 media player for streaming files (.mp3, .mp4, .avi, etc.).

What were your goals for this project?

Our primary goal was to set a solid foundation for future feature development and improvements.

SOLUTION

How did you select this vendor?

We required specialists with solid JavaScript skills and media streaming application development expertise. Having been let down by a previous firm, I chose Jay.devs because they responded quickly to my initial contact.

Describe the project and the services they provided in detail.

The Jay.devs team developed front- and backend software for a HTML5 media player. They provided quality assurance throughout the project by developing test plans and creating test documentation. They performed testing of the developed functionality as well as regression testing.

What was the team composition?

I worked directly with a number of people, including a business development manager, a lead developer, and a QA manager.

RESULTS & FEEDBACK

How was project management arranged and how effective was it?

Their team was extremely responsive in their communication. We spoke most days via Skype, but JIRA was the primary project management tool. We also had weekly status calls.

What did you find most impressive about this company?

Their transparency, effective communication, and operational responsiveness was impressive. Their frontend specialists exceeded our expectations by going the extra mile when it mattered most. They always delivered their work on time and on budget.

Are there any areas for improvement?

I struggle to recall any specific areas for improvement. Our initial concern about dealing with non-native English speakers turned out to be a non-issue as communication was one of their key strengths.
