What I'm looking for

I’m looking to build and architect resilient high-load .NET microservices—especially real-time payments and event-driven streaming—on Kubernetes. I want to lead delivery, mentor teams, and deliver reliable production systems.

I’m a senior .NET backend engineer and software architect with 9+ years building high-load, distributed systems for the fintech and iGaming industries. I specialize in real-time payment (PSP) integrations, event-driven microservices, and low-latency data streaming at scale.

I’ve led cross-functional teams, defined architecture, and delivered resilient services on Kubernetes using Kafka, Redis, and MongoDB. I translate complex business requirements into clean, testable, production-grade systems—focused on reliability, fault tolerance, and operational excellence.

In recent roles, I’ve designed real-time data-streaming microservices with minimal end-to-end latency and integrated multiple PSPs with retries, idempotency, and reconciliation. I also own technical leadership like mentoring, code review, and improving delivery consistency through strong engineering practices.
