What I'm looking for

I'm looking to continue building reliable, high-load backend systems while contributing to architecture, delivery planning, mentoring, and cross-functional collaboration.

I build and maintain Spring Boot microservices for Allianz commercial insurance platforms, supporting underwriters with risk assessment and policy management.

I resolved a critical property-quote performance bottleneck, accelerating calculations for 5,000-location scenarios by up to 35x and delivering the fix to production.

Previously at Sberbank, I built a cybersecurity data-processing service from scratch that handled 600,000 events per second after filtering. I developed Apache Flink and Kafka pipelines for endpoint telemetry, detection workflows, analytical storage, and risk scoring.

I take backend delivery from refinement through production support, while contributing code reviews, architecture alignment, mentoring, onboarding, and Scrum Master responsibilities.
