I am a Java Backend Developer with over 5 years of experience building production-grade backend services using Java, Spring Boot, PostgreSQL, Kafka, and Docker. At DataArt, I streamlined recovery flows and improved onboarding for new developers. Previously, I enhanced order and application flows at EPAM and SKB Kontur, focusing on reliable event-driven integrations, extensive testing, and automated business logic. I excel in observability, troubleshooting, and continuously seek to improve system reliability and developer support. Passionate about clean architecture, I aim to drive technical excellence and mentor future teams.

Built recovery flows for failed external checks, reducing applications stuck in intermediate states to zero. Developed backend workflows for corporate customer onboarding and enhanced production monitoring. Improved troubleshooting by recording state and error reasons. Onboarded and mentored new developers through their first production changes.
