For what projects/services did your company hire Zoftify?
We were looking for a mobile development firm that would help us to improve our 12 tour booking mobile applications built with React Native and supported by Node.js backend.
What were your goals for this project?
The initial goal of the project was to fix several important bugs in our Android app. After developers successfully completed this task, we’ve continued our cooperation.
They’ve implemented complex features for the app (filtering, UI, push notifications) and devops. Along the way they were fixing bugs our clients were reporting in Appstore and Google play reviews.

Please describe your company and your position there.
I am the Project Manager and the Product Owner at a company that helps to increase sales for networked FMCG retailers with more than 50 employees based in several countries. My responsibilities are transportation of big data and mobile development.
For what projects/services did your company hire Zoftify?
We hired Zoftify to refine and improve our existing cross-platform business app. We don't have our own specialists of that profile and experience increasing demand in the development of our app so the company decided to hire outsource professionals.
What were your goals for this project?
We needed to add new functionality as well as improve stability and usability of our mobile app. Also we wanted to improve our app's ratings by making it better in every possible way based on our users' reviews.
How did you select this vendor?
I had been looking for a new mobile development team since we started to have difficulties with our previous one. It took me 2 months and several interviews with different teams and team managers to find and select Zoftify as our new outsouce mobile development team. My decision was based on perfect business communication from this team and also on the highest ratings of my colleagues that have previously worked with these guys.
Describe the project in detail.
Once we managed to agree on legal terms we held several discovery meetings, and after that the team presented us with detailed roadmap of future development along with very helpful suggestions about core functionality and stability improvements.
What was the team composition?
Initially we we given two PMs, each one always having been up to date, two developers and one QA engineer. Due to our increasing demands the team easily expanded to six developers and two QAs, the working processes and inter-teams communications were seamlessly incorporated into our workflow.
Can you share any outcomes from the project that demonstrate progress or success?
After few releases we and our users noticed great improvements in all the desired areas. We started to get two stars higher grades in reviews, also we were able to gather internal feedback using newly integrated Crashlytis service and much more. New functionality always worked as intended, no problems or major bugs in new releases whatsoever.
How effective was the workflow between your team and theirs?
Both PMs are very responsive, proactive and friendly, the team works even on day-offs when it's absolutely necessary to meet the strict deadlines and delivers the best results I ever saw. We have no problems organizing any amount of meetings, both regular and ad-hoc, also we communicate in Slack in most effective ways possible.
What did you find most impressive about this company?
The levels of professionalism and Client-orientation are unparalleled. Zoftify has become not only our trusted outsouce developers but our good friends and colleagues.
Are there any areas for improvement?
There were some minor delays at the beginning of our interaction but it was mostly due to our own lack of documentation so the team had to discover much of the internal workings of our app by themselves, which they managed to do perfectly and came up with very helpful improvements in app architecture, increases in speed and other optimizations.
