About
Senior Java developer with five-plus years building and maintaining core insurance-platform functionality on Guidewire BillingCenter, in Gosu and Java. My focus is integration — wiring complex enterprise systems into the external financial services they depend on, from instant-payment infrastructure to third-party lending platforms, while keeping the code maintainable and production-ready.
Outside Guidewire, I'm expanding into the wider Java ecosystem — Spring Boot, Kafka, Redis, and Kubernetes — carrying the same integration and systems-thinking approach into modern microservice architecture. Comfortable across the full stack of a problem: SQL optimization, cross-schema data work, UI components, production monitoring.
Open to new opportunities in backend development — particularly roles involving system integrations, financial or insurance domain work, or a move into the broader Java/Spring ecosystem.

Core development on Guidewire BillingCenter, plus the integrations that connect it to the outside world. A few highlights from that work:
-
Performance · Load testing
Cutting redundant internal API calls
Partnered with the load-testing team to trace production logs and find redundant internal calls between PolicyCenter and BillingCenter. Eliminated one hot-path call entirely — 24,899 calls per test run down to zero — reducing backend load and request processing time.
-
Integration · SBP
Instant payments via Alfa-Bank
Designed and implemented an integration with SBP, Russia's Faster Payments System, for real-time payment processing.
-
Integration · BNPL
Buy Now, Pay Later — Pochta Bank
Led development from initial design through production launch.
-
Internal tooling
Test-environment uptime monitoring
Built and deployed a Spring Boot monitoring service — polls Bamboo CI, pushes real-time alerts to Telegram and Pachca, backed by Redis for state — cut downtime detection from hours to minutes.
