Sofia Zdobnikova

I’m a Senior Frontend Developer with 12+ years of experience building complex, data-heavy web applications across fintech, trading, real estate, and security domains. I focus on performance, predictable state management, and designing scalable frontend architectures that product and design teams can move with confidently.

In my recent role, I served as the primary frontend engineer for a commission calculation and partner reporting platform built from scratch. I designed a modular React + TypeScript architecture with a shared component layer, fixed major production performance issues using cursor-based incremental loading, and resolved UI regressions caused by incorrect state/effect dependencies.

I’ve also delivered end-to-end improvements across web and mobile: maintaining large-scale React applications with Storyblok-based headless CMS delivery, extending real-time trading interfaces using Redux and RxJS, and raising quality with Jest/Cypress. I’ve built mobile and backend-adjacent capabilities in Flutter and Kotlin/Node.js, and I’m known for translating complex requirements into maintainable UI components.
