I’m a software engineer with 10 years of experience with .NET platform in a creating commercial components for business application developers in a global product company. I have been working on Rich Text Editor and Spreadsheet product. With a team we did tons of tricky algorithms, recreated MS Word and Excel in a .net platform with a love to reliability, quality, performance, and attention to details. Developed several web projects such as company sales platform, file conversion service, sales analytics dashboards. I like to share knowledge and be a mentor. I’m familiar with various languages, tools, paradigms such as OOP, functional programming, and TDD. At the same time, I always try to find the best solution and choose the necessary instrument for a specific task. By knowing several ecosystems (.Net, Node.js, JavaScript), I can find the best solution to complex problems. I can quickly get up to speed, learn new technologies, but at the same time I have sufficient experience and pragmatism to understand when existing solutions are more appropriate. I can work both autonomously and as a team member.
