Web Development Review from James Leonard Ehrlich, DVM

I wanted to outsource front end development while maintaining back end services myself.They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used.The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have.Their professionalism and competency were impressive.I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.

Parallel staff worked on some features for our web app. They also helped us with using the AWS cloud. We used React.js and Node.js for the development of the app. Its frontend was 90% done.

They did not find it, so the team had to create the code from scratch. They also gave me a report of the things that needed to be corrected. From there, they implemented new features that we needed
