Work experience

Senior Frontend Developer

from 03.2022 to 05.2024 (2 years 3 months)
NeoDevelopment, Дистанційно (IT)

Stack: React, Redux Toolkit, MUI, react-hook-form, React.lazy · Team: 15
Led frontend architecture and delivery of Foxi - a B2B SaaS tool for dental clinics handling insurance billing, with an interactive tooth-selection panel and dynamic per-procedure pricing.
Designed a flexible form system that lets clinicians combine and switch between insured and out-of-pocket prices inline, reducing manual billing mistakes and streamlining the claims workflow.
Implemented route- and component-level code splitting with React.lazy, optimised rendering of complex MUI forms, and kept Redux state predictable across multi-step insurance case flows.
Collaborated directly with stakeholders to translate domain (insurance / clinical billing) requirements into frontend data models and UX patterns.

Built a customer-facing dashboard with complex UX: virtualized lists, WebSocket-driven live updates, rich-text (Lexical) editor, dynamic forms, and Redux Toolkit + Redux-Saga architecture.
Designed a reusable form and UI component system in Storybook, consumed across React, WordPress, and PHP projects to standardise validation, error handling.
Rebuilt a legacy iOS application as a React Native (Expo) app using TanStack Query and Expo SDK 55, replacing the outdated App Store version and aligning the mobile experience with the web product.
Migrated styling from SCSS / styled-components to Tailwind CSS across the codebase, reducing unused styles and accelerating UI iteration.
Established a regular dependency maintenance cadence - auditing, upgrading, and patching major/minor versions to keep the codebase secure, up-to-date, and unblocked for new development.
Improved PageSpeed and Core Web Vitals (INP, LCP, CLS) through SSR/SSG with a Headless CMS, code splitting, memoisation, virtualization, and lazy loading; measurable gains in PageSpeed and INP on production dashboards.
Jest, Vitest, and React Testing Library for unit coverage, and Playwright for end-to-end tests on critical flows, stabilising releases and reducing regressions.
Maintained and refactored legacy (pure HTML, CSS, JS) / WordPress frontends; configured GitLab CI/CD pipelines and Docker containers.
