What I'm looking for

I’m looking for a team where I can own end-to-end product development—building scalable React/Node systems, optimizing performance, and shipping AI-powered features—while collaborating closely across product, design, QA, and backend to deliver high-quality outcomes.

I’m a Full Stack Developer with 6+ years of experience building scalable web applications end-to-end—designing frontend experiences and backend services with REST/gRPC APIs, GraphQL, and cloud-based systems. I focus on modern JavaScript/TypeScript ecosystems, performance optimization, and microfrontend architecture, working closely with cross-functional teams to ship production-ready software.

In recent roles, I’ve built and improved production features like a hotel and travel booking platform, data collection and vulnerability monitoring dashboards, and an AI-powered browser extension. I also contribute to AI-powered solutions using RAG with Pinecone, LangChain, and OpenAI, and I strengthen quality through unit tests, code reviews, debugging, and maintainability-focused refactoring.
