About

I spend most of my time making sure money moves correctly. Payments failing silently, KYC flows dropping users mid-onboarding, disbursements hitting the wrong account at 2AM because of a race condition: these are the problems I work on at BharatNXT, a B2B fintech platform processing lending and payment flows for NBFCs across India. Three years in, I have shipped a PPI wallet platform in partnership with Pine Labs, building RBI-compliant settlement guarantees over a webhook-driven state machine on RabbitMQ. On the lending side, I designed the microservice that routes borrowers across 10+ lender partners including IndiaLends and Cashfree, handling 10K+ daily transactions at sub-200ms p99 and $200K/month in disbursements. I also built a KYC orchestration engine that cut manual ops by 35%, and a compliance verification system using LangChain and vector embeddings that automated what used to be a human-in-the-loop document review process. The AI work crept in naturally. When you are parsing unstructured bureau reports and business documents at scale, rule-based systems stop working quickly. LLM extraction with embedding-similarity search was not a trend I followed, it was the only tool that actually solved the problem. My stack is Java, Spring Boot, Go, RabbitMQ, PostgreSQL, GCP, LangChain, and RAG pipelines. But the real skill is knowing when to make a system flexible versus when to make it strict, and fintech usually requires both in the same codebase.
