Experience
barman-tech
Frontend Developer · Full-time, Remote
Full-time remote frontend at barman-tech since January 2026. Production UI for complex web apps — data-heavy panels, real-time surfaces, and maintainable frontend architecture.
- Frontend for complex product surfaces — multi-panel dashboards, state-heavy flows, and ongoing feature, bugfix, and UI improvement work.
- Ketabfeed — WooCommerce / Elementor theme customization (Parsan-based) through barman-tech.
Graphay
Freelance Frontend
Freelance frontend through Graphay until I became full-time at barman-tech in January 2026 — a collaborating studio, not a current employer. I owned frontend implementation; other tech and design members were a team.
- Octopus AI — a Graphay freelance product, ChatGPT-like but more specialized at the time: generate video, Excel files, and research, plus plugins added by writing Python scripts (when that was not yet trivial in ChatGPT).
- Adgame Telegram mini-app front-end — Telegram SDK, TON Connect wallet UI, ads/referral surfaces.
- Detifi — Graphay-related AI chatbot for crypto market review/analysis for trading; product later stopped. Frontend only — not a separate employer (see Projects).
Techsnovel
Frontend Developer · Contract
Frontend for an AI shopping-guide bot for e-commerce stores, shipped as a Wix plugin — not merged with Graphay Octopus work.
- The bot uses the store’s products plus defined rules and extra rules the merchant adds, so guidance is store-specific — to speed sales and walk the customer through buying.
- Real-time chat UI with SignalR — typing indicators, message queue, and RBAC-aware roles (React, TypeScript, Zustand).
Collaborations
Freelance Frontend · Product UI
Freelance frontend with product teams — brand collaborations listed separately.
- Takanesh Academy, PARSDATA, Arsal Web, Mark It Done, and other product UI engagements.
Education
