Full-stack developer building React/Node apps and LLM-powered search for production systems.
IndiaWhat I'm looking for
I’m a full-stack developer with 3.5+ 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.
