I build serverless, backend-heavy web applications and multi-tenant AI/RAG platforms.
IndiaWhat I'm looking for
I've built backend-heavy web applications and serverless systems with Node.js, React, TypeScript, and AWS, with recent work centered on multi-tenant AI/RAG infrastructure.
In ContextSpace, I built a multi-tenant serverless RAG platform using AWS Lambda, SQS, Amazon Bedrock, Aurora PostgreSQL with pgvector, and MongoDB. I designed event-driven document processing, retrieval isolation, JWT authentication, protected APIs, and reliability features including retries and graceful degradation.
At Jewellerskart & Mani Web Solutions, I built reusable React components that reduced update cycles by 30%, optimized MongoDB performance, and developed MERN backends with JWT authentication and AWS automation. I've also built a serverless auction platform with AWS CDK, Lambda, DynamoDB, EventBridge, and SQS.
