Uchkun Rakhimov
Backend Engineer — specializing in scalable distributed systems
I'm a backend engineer with 3+ years of experience building scalable, high-performance systems. My core stack includes Node.js, TypeScript, and frameworks like NestJS, Express, and Fastify, backed by PostgreSQL and MongoDB. I architect distributed services on GCP, implement robust CI/CD pipelines, and maintain comprehensive monitoring and logging. On the frontend, I work with React.js to deliver complete, end-to-end solutions.
