Frontend engineer with 8+ years of production experience. I build interfaces for hardware and software: self-checkout kiosks, autonomous cleaning robots, barcode scanners, online grocery, chatbot builders, and marketing platforms.
I work alone on a product or inside a team, at large companies and small ones.
Project details
- Cash payments for 2,000+ self-checkout kiosks. Added to software already running in stores, without replacing it. A real-time WebSocket layer covers 60+ hardware states and 10+ payment, maintenance, and diagnostic flows. Each kiosk handles about 300 cash transactions a day.
- Fleet dashboard for 200+ autonomous cleaning robots. Designed and built from scratch: 20+ screens for live status, routes, schedules, parts diagnostics, and field-engineer tasks, with role-based access.
- Shelf label linking for retail stores. A store app that links electronic shelf labels to products by barcode scanner, phone camera, or manual entry. Throughput rose from 6 to 7 labels per minute to about 50. Piloted in 12 stores.
- Online grocery delivery frontend. Catalog, product pages, and cart for a national retailer's digital arm. Handles 270,000+ orders on peak days.
- No-code chatbot builder. React and TypeScript frontend with a drag-and-drop flow editor, used by 200+ businesses across Russia and the CIS.
- onscan-next. Open-source (MIT) typed library for hardware barcode scanners. Works with React, Vue, and Angular, and includes a
simulate()API for tests without a physical scanner.
Store counts: X5 Group, as of December 31, 2025. Self-checkouts: estimated as a quarter of 25,533 Pyaterochka stores with three each. Cash payments: 2,000 kiosks at about 300 a day.
I set the team standard for AI development tools across four frontend projects. That covers Claude Code and OpenCode, internal webinars on both, and CodeRabbit for automated review. I also built an AI meeting-notes bot that saves several hours of manual work per week.
