What I'm looking for

I seek senior engineering roles designing scalable distributed systems and microservices at product-driven companies that value performance, reliability, mentorship, and technical leadership, with scope to optimize systems and lead high-impact initiatives.

I am a Senior Java Engineer with 6+ years building enterprise-scale distributed systems and microservices for fintech and blockchain environments. I focus on performance, reliability, and clean architecture, delivering systems that serve millions with high uptime SLAs.

I have led migrations from monoliths to microservices, optimized JVM performance and databases to reduce latency and costs, and mentored engineering teams while spearheading technical initiatives in observability, event-driven design, and workflow orchestration.
