I build production backend systems across fintech, banking, and enterprise SaaS, and I’m currently designing a unified multi-provider LLM gateway at PayPal scale. It’s a single reactive Spring Boot API that routes buffered and streaming traffic across Anthropic Claude, OpenAI/Azure OpenAI, Google Vertex AI, and xAI.

I’ve been shipping security and governance layers too—token-based auth with user/org resolution, Bucket4j rate limiting, monthly spend governance, and DLP redaction for requests and responses. I also wire in end-to-end observability with Datadog LLM spans and manage distributed state using Redis, MySQL/PostgreSQL, and Caffeine.

Before this, for seven years I delivered secure, high-compliance services like fraud-risk-management components for Standard Chartered’s internet banking platform (Account Drainage, Cooling Period, Kill Switch, and device/soft-token integration) plus web services at SAP Labs. I focus on multithreading and concurrency, Kafka-driven architectures, and solid SQL/NoSQL data modeling, working through Agile/Scrum with CI/CD on Azure/AWS and Docker + Kubernetes/OpenShift.
