Armenia

Message

At Yandex, I develop and own product features for a large-scale React application serving over 10 million users. I redesigned the automated testing pipeline to support parallel execution, reducing CI feedback time by 40% and improving test stability by 30%.

I also improved the localization workflow, reducing translation management effort by 80%, and contributed to frontend architecture and internal developer tooling. At Heavyglare, I developed customer-facing features for a Shopify platform and automated catalog and pricing management with Python.

I built Family Multibank, a full-stack banking platform, and received a Special Nomination at the VTB API Hackathon 2025. I also developed Sortify, an interactive React platform for visualizing sorting algorithms.
