I build high-throughput distributed backend systems for real-time betting, gaming, payments, and enterprise platforms.

I've built high-throughput distributed systems for betting, gaming, financial transactions, and enterprise platforms for more than 12 years.

At Loranlord Project Services, I architected a Sportsbook Integration Engine with under-50ms p99 latency and scaled a multi-currency ledger to more than 390K active accounts and 3.9M wallet balances.

At StakeLogic, I designed real-time live-dealer backend platforms, Kafka integration between studio hardware and services, and WebSocket/SSE infrastructure supporting tens of thousands of concurrent users. I also introduced load testing and observability practices that supported 99.9% game uptime.

I've led teams, mentored developers, reviewed code across 48 repositories, and driven architecture, testing, and CI/CD standards. My work centers on Java, Spring, event-driven systems, resilient transaction processing, and platforms that must stay correct under heavy concurrent load.
