My name is Egor and I am an experienced and professional Javascript developer. My specialization is the creation of back-end and front-end parts for websites and web applications, as well as blockchain development of any complexity. I help my clients to implement any of their ideas the way they want. For 5 years of working in various web studios on top-level projects, I have learned a huge number of technologies and developed clear principles: - I never lose touch - I always bring the project to the end - I do not do work at a lower level than in the portfolio
