Senior Full-Stack Developer (Node.js / Go)

I deliver end-to-end web, mobile, and realtime systems as a freelance developer and product builder. My work includes architecting and shipping production backends in Go and Node.js/Express, using clean layered architectures across domain, service, and controller layers.

I build WebSocket-based products such as chats, live-update systems, auctions, and push notifications. I also develop Next.js and React frontends, React Native/Expo mobile apps, Telegram bots and Mini Apps, and responsive SEO-optimized corporate websites and landing pages.

I own infrastructure and delivery workflows, including Docker, Docker Compose, Nginx reverse proxies with TLS, PostgreSQL migrations, Redis, CI/CD, and Swagger/OpenAPI documentation. I have integrated payment providers and recurring subscriptions, implemented queues, cron jobs, and indexers that synchronize on-chain events into PostgreSQL.

Worked as an in-house Web Developer, developing and maintaining corporate websites and landing pages.

Converted mockups into responsive, SEO-optimized pages and implemented interactive features and external integrations. Handled ongoing site maintenance, performance improvements, and security fixes.

Bachelor of Science in Computer Networks.
