At Nomura, I led the architecture and delivery of transaction processing platforms supporting 50M+ daily financial operations. I modernized 12 mission-critical services through cloud-native microservices and engineered a RAG pipeline with LangChain and Redis for 10M+ embeddings.
Previously, at Barclays, I led the migration of 17 production services to AWS and designed OAuth2 authentication and authorization platforms. My earlier work includes financial stream architectures handling 30M+ records at Standard Chartered Bank (via Synechron), and low-latency service communication at 3FramesLab.
