About

High-scale UI systems, shipped reliably

7+ years delivering high-scale, performant UI systems for FinTech and platforms serving millions — including daily deployments at Sberbank and acting frontend tech-lead ownership for the shared react-ui library used across 15+ microservices at CRX Markets.

She came up through the full stack — Java/Spring Boot, JOOQ and REST — which is why her frontends integrate cleanly with the systems behind them. Beyond shipping code, she is a former tutor for 26+ mathematics, economics, and finance courses across school, undergraduate, and doctoral levels — sharpening her ability to master complex domains and mentor teams.

"Coding is my hobby — not just my job."

"I get inspired and motivated by challenging projects, meaningful deadlines, and seeing my work reflected in positive reviews from users and teammates."
