I build production fintech systems and ship LLM-powered features across Java, Spring Boot, React, and AWS.
IndiaWhat I'm looking for
At Osttra, I own backend services and React dashboards for post-trade infrastructure used by 150+ institutional trading desks. I led a legacy reconciliation migration that eliminated a recurring class of overnight production incidents.
I built a React and AG Grid trading dashboard processing about 500K daily transactions, reducing analyst reconciliation time by roughly 30%. I also co-built Dhruva AI, a voice-driven in-product agent that turns analyst speech into structured intents and executes dashboard actions.
Previously at eGain, I shipped across a 12-microservice enterprise chat and email SaaS product serving about 50K daily users, cutting API latency by around 42%. At Capgemini, I progressed from React Developer Intern to Full-Stack Developer and built Java, Spring Boot, and React systems for government geospatial workflows processing about 2M records daily.
I'm focused on end-to-end ownership, from requirements and backend reliability to product-facing AI features. I build with Java, Spring Boot, React, AWS, and practical LLM patterns including structured output, function calling, and RAG.
