At an international online casino operator, I led a backend team of 8 developers working on a platform for games, bets, payments, bonuses, and provider integrations. The platform handled 2 million transactions per day.
I developed and supported its high-load services with Laravel, PostgreSQL, Redis, and Apache Kafka. I designed event exchange with guaranteed delivery using the Outbox pattern, idempotent consumers, retries, and dead-letter topics.
I designed a flexible bonus and loyalty system and integrated Slotegrator, SoftSwiss, and Digitain through a middleware layer. The work reduced the connection time for a new provider from 3 weeks to 4–5 days.
Previously, at lmctplus.com, I integrated Stripe and ClickFunnels APIs and helped refactor a monolith into a modular architecture. I also optimized the affiliate-store catalog, decreasing response time by 80%.
