## About

Senior Backend Engineer with 10\+ years of experience architecting distributed systems and production platforms using Java, Spring Boot, Kafka, and PostgreSQL across networking, fintech, and privacy/ESG\. Led platform modernization, secure SSO, high\-volume payment processing, and production LLM/vision integrations — including a consolidation initiative contributing to an estimated $7M in potential cost savings\. Highlights: • SSO across 3 services — auth latency cut from 3 sec → 800 ms \(\~73%\) • Led a 4\-engineer team; migrated 65K access points into a unified network \(\~$7M potential savings\) • Payment settlement platform: 10M\+ txn/day design, 3–5M settlements, \~417 TPS within a 2\-hour SLA • Production AI \(Claude Vision\): API cost ↓42%, latency 600ms → 180ms What I’m known for: • System design for microservices and high\-throughput integrations • Taking ambiguous platform problems from architecture → production • Performance, cost, and resilience \(caching, rate limits, circuit breakers, DLQ\) • Practical AI integration \(LLM/vision APIs, RAG\) — product features, not demos Stack: Java, Spring Boot, Kafka, PostgreSQL, AWS/Docker, Python/ETL, RAG/pgvector Open to Senior Backend / Platform / Distributed Systems roles where ownership, architecture depth, and measurable impact matter\.
