EXPERIENCE

Middle Frontend Developer, (Startup) - Language Learning Mar 2026 – Present
● Own the vocabulary and interactive-lesson modules in a mobile-first, Duolingo-style learning app, built with React,
TypeScript, SCSS, and Zustand.
● Design reusable UI components shared across the lesson, review, and progress-tracking flows to keep the codebase
consistent as features ship weekly.
● Build PWA-ready functionality (installable app, responsive layouts) so the product works consistently across
desktop and mobile without a native app.
● Work directly with founders and product on feature scoping in a fast-moving startup environment, translating
loosely defined ideas into shippable UI.
Frontend Developer, (Freelance) - Real-Time Chat Platform Nov 2025 – Feb 2026
● Built a multi-room chat application in React, TypeScript, REST, and WebSockets, including reconnection handling
so message delivery stays reliable when a connection drops.
● Implemented live message delivery and connection-state UI (sending / sent / disconnected) so users always know
the true state of their messages.
● Kept chat history consistent by synchronizing persisted REST data with the live WebSocket stream, avoiding
duplicate or out-of-order messages on reconnect.
● Delivered the frontend independently for a freelance client, from UI implementation through responsive testing on
desktop and mobile.
Frontend Developer - (Contract) - SoftServe Apr 2025 – Oct 2025
● Built a movie-streaming platform frontend in React and TypeScript as part of a 5-person team (3 frontend, backend,
UI/UX design).
● Developed reusable UI components used across desktop, tablet, and mobile breakpoints, reducing duplicated layout
code across views.
● Integrated REST APIs with proper async/loading/error states, so slow or failed requests degrade gracefully instead
of breaking the UI.
● Contributed to a Git-based code review workflow, giving and applying peer feedback on a shared codebase.

Frontend Developer, (Freelance) - Event Booking Platform Dec 2024 – Mar 2025
● Built a responsive event-booking site in React and TypeScript for an entertainment-industry client, including an
interactive seat-selection UI.
● Implemented event filtering and search so users could narrow large event lists quickly.
● Reduced initial load weight using lazy loading and code splitting on non-critical routes.
 ● Worked directly with a non-technical client to translate feedback into scoped UI changes - first experience
managing client expectations solo.

PROJECT — MOVIE CATALOG PLATFORM
React · TypeScript · Tailwind CSS · Redux Toolkit · RTK Query · Zod · React Hook Form
● Built a movie-streaming web app with authentication (React Hook Form + Zod validation) covering login and
registration.
● Integrated 10+ REST endpoints via RTK Query for caching, background sync, and data fetching.
● Implemented global state management, including a favorites system, with Redux Toolkit.
● Added multi-language support (EN, DE, UA, RU) and persistent theme switching, with a fully responsive mobile-
first layout.

EDUCATION
