I build reliable Go backends for high-load fintech and iGaming platforms.
SerbiaWhat I'm looking for
At EGT Digital, I build Go services for slot games, including bonus rounds, cascading reels, free spins, multipliers, cryptographically secure RNG, and reproducible spins for audit and certification.
I built Kafka-based processing for roughly 500,000 daily transaction and status events, using retries, idempotency, and dead-letter queues. I also split a large backend module into Go microservices, reducing production issue resolution time from 47 to 11 minutes.
Previously at Pave Bank, I delivered card-payment settlement batching and counterparty verification services, cutting verification p95 latency from about 3 seconds to 600 ms and selected PostgreSQL query times from about 900 ms to 180 ms.
