What I'm looking for

I seek backend engineering roles focused on Java/Spring microservices, identity/security, and messaging at companies valuing reliability, observability, and cross-functional collaboration.

I am a Java backend engineer with 5+ years building scalable services, CIAM solutions, and high-throughput messaging platforms. I deliver low-latency REST endpoints, resilient integrations, and observability features while protecting sensitive PII and ensuring compliance.

I have driven migrations from monoliths to microservices, implemented circuit breakers and trace IDs, and reduced latency and operational load through CDC, outbox patterns, and event-driven design. I collaborate closely with product and back-office teams to produce reliable, measurable production outcomes.
