What I'm looking for

I’m eager to join a remote team where I can use my portfolio to build production-grade full-stack systems with real-time features and AI capabilities, and I’m fully flexible for EU/US business hours.

I’m a results-driven Full-Stack Engineer specializing in real-time systems, AI platforms, and scalable backends, with a proven ability to independently architect and deploy production-grade applications. I’m adept at self-directed problem-solving, managing CI/CD pipelines, and writing clean, type-safe code that’s easier to trust and maintain.

In my projects, I’ve built a scalable e-commerce monorepo (TechVault) with JWT refresh token rotation, role-based access control, and Stripe webhook verification—achieving zero payment processing failures in production. I also developed real-time collaboration and live syncing (FlowDesk) using Socket.IO and Redis Pub/Sub, and created an AI-powered developer toolbox (DevKit) that integrates in-browser SQLite via WebAssembly and contextual analysis with Vercel AI SDK and Google Gemini.
