A mature trader Umar Ashraf reached out to us with an idea of a unique trading journal. Umar worked on his product for a year with two external teams. However, the results of that cooperation were insufficient - the product was unstable, had poor UX, lacked crucial functionality and test coverage.

Our team started the rescue mission by reshaping the development strategy and resetting the task priorities. We refactored code, significantly improved code test coverage, product stability and performance, and redesigned UI/UX. As a result, we got a working and stable product that quickly started growing in the number of new users.

Now, the work on the product continues. We regularly collect the users' feedback, plan and implement product improvements and new functionality.
