Senior Software Engineer — High-Load Systems & Event-Driven Architecture 14 years of experience building scalable back-end systems in Java/Spring and Node.js.
I'm a Senior Software Engineer specializing in building scalable back-end systems for demanding, high-throughput industries like iGaming. My core expertise is the Java/Spring and Node.js ecosystems, with a heavy focus on designing and scaling high-performance microservices.
I thrive on the challenges of high-load systems — managing high concurrency, ensuring low latency, and optimizing real-time data flow. I lean heavily on Apache Kafka to build robust, event-driven systems that scale.
For the last 4 years I've worked in the iGaming domain, building regulatory reporting systems across multiple jurisdictions on a Kafka + Java/Spring stack.

"Do or do not, there is no try."
- Architectural rigor — I design systems, not just code: evaluating trade-offs and picking the right tool (relational PostgreSQL vs. high-throughput DynamoDB).
- High-load & event-driven — high concurrency, low latency, real-time data flow, and scalable Kafka-based event streaming.
- Cloud-native mindset — AWS Solutions Architect depth; secure, observable, cost-efficient applications built with the infrastructure in mind.
- Clean code & collaboration — deep discussions on semantics and shared understanding; code review and mentoring.
