Специализация: Flutter Developer

Almost 6 years of experience in Software Engineering with proficiency in building scalable web services and mobile apps with Flutter. I was on both sides of what customers see and what not - frontend and backend,and I'm excited to build great, perfect mobile apps most of all. The best driver for me is the usefulness of the product to users and the impact the product can have on that world. Make it a better place. It is because of this I’ve created a few Open Source projects,which are used by thousands of developers all over the world, andcreated a lot of great products which help people right now.
