Experience
Backend Software Engineer
Azul · Limassol, Cyprus
January 2025 – June 2026
Designed and delivered multiple backend services for vulnerability data processing and enrichment within a JVM ecosystem, including AI-assisted detection of impacted code elements and a centralized CPE/CVE processing pipeline. Established system observability with Grafana to ensure reliability and performance at scale.
- Average CVE and CPE ingestion time decreased from 24h to 8h, ensuring compliance with a 24-hour security SLA.
- Class/Method-level vulnerability coverage improved from 15% to 75% through automation of data collection and analysis.
- Migrated the system from a monolithic to a microservices architecture, enabling independent scaling of components and improving overall system flexibility and maintainability.
Software Engineer in Test
Azul · Yerevan, Armenia (relocation to Cyprus)
April 2023 – January 2025
Improved the quality, reliability, and performance of the automated testing pipeline by introducing structured test planning, expanding automation coverage, and optimizing test execution strategy. Collaborated with developers and product managers to define comprehensive test plans, implemented automated tests for new features, and refactored existing test code to improve maintainability and scalability.
- Automated test coverage increased from 60% to 80%, improving overall product quality and reducing regression risks.
- Flaky test rate reduced from 30% to <1%, significantly increasing test reliability and developer trust in CI results.
- Average pipeline test execution time decreased from 2 hours to 1 hour by splitting tests by scope and executing only impacted tests per pipeline.
Java Backend Developer
Yandex · Yerevan, Armenia
January 2023 – April 2023
Implemented a billing service designed for the creation and management of promotional offers and subscriptions. The system enabled quick and flexible setup of new promotions with configurable conditions. The system allows non-engineering teams to independently create and manage offers without requiring code changes or database migrations.
- Time-to-market for new promotions reduced from days to hours, eliminating dependency on engineering team.
Kotlin Backend Developer
Tinkoff · St.Petersburg, Russia (relocation to Armenia)
May 2021 – January 2023
Designed and delivered multiple high-load backend services and infrastructure components, including workflow orchestration, low-latency data services, distributed data migration, and internal execution frameworks. Focused on scalability, reliability, and automation across distributed systems.
- Enabled stable handling of 10k+ RPS by building a customer data service, establishing a single source of truth for multiple internal platforms.
- Reduced manual data migration effort and automated large-scale transfers, processing millions of records across PostgreSQL and Oracle systems.
- Test coverage increased by 50% and regression cycle time reduced by 70% by introducing an automated testing framework integrated into CI/CD pipelines.
