PROFILE

Andrii Shalaienko

Andrii Shalaenko developed robust event-driven features and messaging infrastructure across the webitel/cases and webitel/engine repositories, focusing on scalable case event visibility and reliable trigger processing. He implemented a watcher system using Go and RabbitMQ to deliver real-time notifications for case changes, simplifying queue management with topic-based routing. In webitel/engine, he enhanced trigger reliability by introducing AMQP error handling, reconnection logic, and improved domain-aware processing. Shalaenko also contributed to webitel/protos by refining API definitions and protocol buffer schemas. His work demonstrated depth in backend development, concurrency, and system integration, resulting in more resilient, maintainable, and observable business workflows.

March 2025 performance highlights: Delivered a simplified, scalable messaging path and reinforced trigger processing reliability across webitel/cases and webitel/engine. Key outcomes include reduced queue management overhead via a unified topic-based routing design, more robust AMQP handling with automatic reconnection and improved trigger defaults, and a fix to domain_id retrieval ensuring correct type-based trigger queries. These changes strengthen system resilience, reduce operational risk, and improve data consistency for domain-scoped triggers across services.
