What I'm looking for

I'm looking to build scalable Java backend and distributed fintech systems, with opportunities to work on payment platforms, event-driven architecture, cloud-native services, observability, and GenAI applications.

At Oracle Financial Services Software, I build concurrent Java microservices for UPI, IMPS, and card payment systems, sustaining approximately 1000 TPS across 2–3M users.

I develop and maintain 50+ Java microservices and REST APIs for Oracle Banking Platform workflows, deploy Dockerized services on Kubernetes, and strengthen interbank payment security through request signing, verification, and data-integrity modules for NPCI and HDFC Bank integrations. I also improved Apache Velocity code generation to accelerate SOAP and REST delivery by 40%.

I build observability and AI-powered banking tools, including a multithreaded monitoring framework, GraphQL payload optimization, Payload Probe, and a LangChain4j RAG assistant for payment-transaction investigation and banking operations queries.
