What I'm looking for

I'm looking for a remote backend role on a product with real load and sensitive data, especially in payments, fintech, or high-load services.

I've built payment infrastructure for a high-load iGaming and payments platform at Social Media Holding, integrating 50+ providers across 20+ countries and supporting 200+ payment-method combinations.

I extend configurable payment integrations, build resilience for provider outages, and keep transaction systems secure. My work has included fixing SQL injection risks, eliminating distributed registration race conditions, and implementing immediate refresh-token revocation with cache failover.

I also moved heavy transaction-history reads to ClickHouse, improved failing admin workflows, and joined on-call rotations for production incidents, releases, and Grafana/Slack alerting. I work primarily with PHP, Laravel, PostgreSQL, Redis, RabbitMQ, Docker, OAuth2/JWT, PHPUnit, and PHPStan.

Alongside commercial work, I've built a Google Trends discovery platform with a proxy-pool parser architecture and a real-time Go bot for Chatwoot dialog assignment. I own architecture, integrations, and infrastructure, using AI-assisted development where it helps me move faster.
