Nik Yaskevich
📅 Present
I am a 25 years old from Poland who loves technology, coding, architecture and volleyboll!
Hey, I'm Nikita! I'm a dedicated Senior Full Stack Developer with a strong focus on front-end development, particularly with React, Next.js, and Golang, Node.js. I bring solid expertise in Typescript, JavaScript and have commercial experience with modern frameworks and tools, including PostgreSQL GraphQL, AWS, Docker and Redis.
Currently leading frontend development for an startup fintech platform, working directly with business and stakeholders, mentoring engineers, running code reviews, and staying hands-on with code. I enjoy taking complex problems (configurators, 3rd party integrations, performance bottlenecks) and turning them into predictable, scalable solutions.
