I build performant Node.js APIs and RAG systems with TypeScript and PostgreSQL.
IndiaWhat I'm looking for
I've built three full-stack systems end-to-end, including Second Brain, ResearchOS, and MedBot, covering backend architecture, data modeling, API design, authentication, validation, logging, and error handling.
In Second Brain, I built 12 REST endpoints and improved API response time by approximately 40% through Redis caching and query optimization. I also implemented asynchronous URL enrichment with BullMQ workers, retries, exponential backoff, and Open Graph metadata extraction.
My work in generative AI includes RAG pipelines, semantic retrieval, LangChain orchestration, multi-agent research workflows, and pgvector-based cosine-similarity search using 768-dimensional embeddings.
