What I'm looking for

I’m looking to build production-grade web products end to end—React/Node frontends, scalable APIs, and practical AI features—where I can own architecture, improve performance, and ship quickly with strong engineering collaboration.

I’m a full-stack developer with 3.9 years of experience building web applications using React and Node.js. I focus on responsive UIs, scalable backend APIs, and performance optimization for real-world usage, and I’ve integrated LLM-based features to make search and automation more useful in production systems.

Most recently, I built a document search system using OpenAI embeddings and Pinecone, improving search relevance through prompt tuning and chunk optimization. I’ve also reduced MongoDB query latency by 20% with aggregation pipeline optimization and Redis caching, led backend development as the sole engineer for MVPs from zero to production in 6-week timelines, and implemented multilingual i18n support across React and React Native without breaking existing flows.
