India

Message

At Kiwi General Insurance, I designed and built a Policy Management microservice for policy issuance, endorsements, renewals, versioning, and audit trails. I also created shared Kafka libraries and event-driven document processing using AWS EventBridge and S3 pre-signed URLs.

At CodeREADr, I improved retrieval API efficiency by 50–60% through MongoDB query optimization and led the UI migration from Vue 2 to Vue 3. I also built password-protected share links with configurable expiry dates, increasing user engagement by 30%.

I built an agentic chatbot with LangChain and LangGraph that integrates OpenAI, Gemini, and Groq, streams responses, and uses custom MCP tools. Earlier, at Vnnogile Solutions Pvt. Limited, I developed recommendation engines and implemented Redis Streams communication between microservices.
