Pratik Bhattarai

I’m a Software Developer focused on building scalable backend and full-stack applications using TypeScript, Node.js, NestJS, React, Next.js, Java, and Spring Boot. I enjoy working on systems where clean backend architecture, reliable APIs, data processing, and modern AI capabilities come together to solve real application problems.


My recent work includes building multi-tenant AI platforms, RAG-based assistants, hybrid BM25 + vector retrieval systems, asynchronous document-processing pipelines, and multi-agent research workflows. I’ve worked with technologies including PostgreSQL, Pinecone, Qdrant, Redis, BullMQ, Docker, Firecrawl, Jina Embeddings, Groq, WebSockets, and REST APIs. I’ve also implemented secure authentication, real-time features, semantic search, payment integrations, and organization-scoped data isolation.
