At Double Coconut, I own backend architecture and technical direction across seven microservices for a logistics platform supporting 15K+ daily active users and 500+ peak production RPS. I improved Load Board throughput 10× under load tests, reaching sub-300ms P95 latency.
I built a resilience layer for cross-service authentication and published a shared npm package used by all services. I also implemented distributed tracing and centralized observability, and reduced AWS costs by about 20% through EC2 right-sizing.
At Coinstats, I integrated cryptocurrency exchange and wallet APIs into a portfolio tracker and built real-time notification services. I optimized portfolio data schemas, reducing query execution time by 40% and enabling sub-200ms P95 latency for critical data retrievals.
At Energaming (iGaming), I developed the complete backend for a real-money multiplayer card game, including its game engine, rule enforcement, state management, and real-time event handling. I also built the full backend for a Rock–Paper–Scissors game on the same platform.
