À propos de moi
Hi, I'm Anastasia — a senior frontend engineer with 6+ years in React / TypeScript / Next.js, 12 years in software overall, and a QA background that makes my code unusually hard to break.
I build: dashboards, data tables, real-time WebSocket UIs, admin panels, landing pages, responsive HTML5 / CSS3 / SCSS / Tailwind layouts, component libraries, SSR/CSR with Next.js App Router.
Open-source contributor (Prebid.js). Redux, React Query, D3.js, Recharts, REST APIs. Tech lead experience.
Whether you have a Figma, a messy codebase, or just an idea — I'll build it right. — Anastasia

Organised a cross-product styling system adopted across the company’s multiple regional branches, improving consistency and development speed. Integrated frontend with a microservice-based backend using strongly typed data contracts; collaborated cross-functionally with product stakeholders, backend engineers, and client representatives.
