Frontend Engineer. I build things that most developers avoid — visual editors, real-time collaborative systems, enterprise-grade data grids, and DeFi interfaces.
- Visual Editors — built a presentation editor twice: first on Canvas, then migrated to DOM. I know the tradeoffs between the two.
- Enterprise at Scale — my component library at a major bank is used across dozens of internal products.
- Real-Time — collaborative editing, SSE pipelines, WebSocket-based multi-user systems.
- Web3 — Solana DEX, wallet integrations, smart contracts on Solidity.
Currently building an AI-powered presentation platform and shipping headless table widgets.

Visual slide editor built from scratch — first on Canvas (Fabric.js), then re-architected as DOM-based. Rich text, image masking, real-time SSE pipeline to AI backend. Performance-critical state management for smooth drag/resize interactions. |
Production UI kit for a major Russian bank — canvas-powered data grid, drag-and-drop dashboards, analytical widgets, form system. Monorepo with Storybook, visual regression testing, design system integration. |
|
Composable table system on top of TanStack Table — sorting, filtering, tree management, cell editing, virtualization, collaborative locking. Headless core, fully typed, tested with unit and E2E suites. |
Crypto exchange frontend with wallet integrations, on-chain transaction signing, locale-aware numeric input with precision math. Bidirectional quoting, swap route visualization, multi-language support. |
