I’m a fullstack engineer with 5+ years of experience building production-grade applications, with a strong focus on React/TypeScript on the frontend and NestJS (Node.js) on the backend. I enjoy turning complex requirements into clean APIs, responsive UIs, and reliable systems—especially when performance, observability, and test coverage matter. In recent work I’ve architected microservices, optimized database performance, and built event-driven pipelines using NATS/RabbitMQ alongside PostgreSQL and Redis. I also bring hands-on experience with data ingestion and computer-vision/ML production workflows (YOLOv8 → Florence-2 → SLBR watermark removal), and I use AI-assisted development tools like Claude Code to speed up iteration while keeping quality high.…I’m a fullstack engineer with 5+ years of experience building production-grade applications, with a strong focus on React/TypeScript on the frontend and NestJS (Node.js) on the backend.
