  • May 2019 - Present

  I joined the project at MVP state just before going live. I’m one of the core developers who has re-built the whole iOS project architecture, dividing the application into separate easy testable layers, applying the best architectural solutions to make the app very flexible and extendable. My deep dive of multithreading has made the app very responsible, robust and user friendly. I’ve built a lot of core services and components which allow new features to be developed fast and easily, making them robust, maintainable and working seamlessly. The important note is that all this huge work is being done during the continuous delivering process of the new features to production, step-by-step introducing new architectural solutions and conquering new areas of existing parts of code which were waiting to be rebuilt. One more big achievement can be emphasised, I've developed several complex algorithms which were adopted among all platforms of the project (iOS, Android, Web, Backend). Show less
