About me
Full-stack developer focused on building modern, reliable, and scalable web applications. I work with React, Next.js, TypeScript, Node.js, NestJS, PostgreSQL, REST APIs, and Docker.
I can build projects from scratch, develop MVPs and SaaS products, implement new features, integrate APIs, fix bugs, improve performance, and work with existing codebases. I’m also comfortable taking over unfinished projects and bringing them to a stable, production-ready state.
I focus on clean architecture, maintainable code, practical solutions, and clear communication. My goal is not just to make something work, but to build solutions that are easy to develop and maintain further.
