Portfolio

Telcell Market

● I worked as a frontend developer responsible for building and maintaining three platforms (Seller, Buyer, Admin) for the first Armenian marketplace. ● I developed a shared UI library that included a design system and reusable functions used across all platforms, following the Atomic Design Pattern architecture. ● The codebase was fully documented using Storybook for UI components and JSDoc for functionality. ● I wrote tests with Jest and Cypress to ensure application reliability. ● I implemented light and dark themes using styled-components and added multilingual support with i18next. ● I successfully integrated tools like Yandex Maps and Firebase with platform-specific features. ● I also developed animated landing pages with parallax effects using Framer Motion and styled-components. ● To improve performance, I optimized the application using Lighthouse and bundle analysis tools. ● Additionally, I configured Prettier and ESLint for consistent code quality and participated in regular code reviews.

Rusarm Transits

● At Rusarm Transits, I worked as a frontend developer on a transport platform (rusarm-transits.am), where I implemented backend-like functionality entirely on the frontend using Firebase tools such as Firestore, Realtime Database, Cloud Functions, and Hosting. ● I developed an online ticket ordering system with user authentication through the Telegram API. ● Additionally, I built an email notification system for flight updates using react-email and Firebase API.

Dinely

● At Dinely, I worked as a frontend developer focused on delivering a seamless digital dining experience, allowing guests to order and pay directly from their phones—no app required. ● I built and integrated a QR-code ordering system that connected diners to interactive, AI-powered menus for fast and intuitive ordering. ● I developed admin and seller dashboards enhanced with AI capabilities to simplify menu management, item availability, and order processing. ● Additionally, I designed and implemented a high-converting, responsive landing page to attract new restaurants and partners. ● Throughout the project, I collaborated closely with backend and design teams to ensure scalable architecture and pixel-perfect UI.
