About me
Solo full-stack developer from Ukraine, building production systems end-to-end — architecture, backend, frontend, deployment. I'm an AI-augmented developer: I use tools like Claude to move fast, but every architectural decision (data isolation, security, service boundaries) is mine, not blindly generated. My main stack is React, Next.js, Node.js, TypeScript, and Rust for performance-critical parts. Recently shipped Mutuals, a real-time social platform with microservices architecture, live chat infrastructure, and a full admin/moderation system — deployed to production with Docker and CI/CD....

Solo developer building production systems end-to-end — architecture, backend, frontend, deployment. Recently shipped Mutuals, a social platform with microservices (TypeScript + Rust), real-time chat infrastructure, and a full admin/moderation system, deployed to production with Docker, GitHub Actions, and CI/CD. Comfortable across the full stack: service architecture with strict data isolation, WebSocket real-time systems, containerized deployment, and production security practices (secrets handling, rate limiting, role-based access). I use AI coding tools (Claude Code) heavily to move fast without cutting corners — every architectural decision is deliberate, not generated blindly.
