---

Senior Frontend Engineer with 8+ years delivering products from prototype to production: architecture, estimates, long-term maintenance. Strong on AI tooling (LLM, MCP, Claude Code), strict typing, and decomposition. Focused on product thinking and feature delivery.

• Core stack: Vue 3 / Nuxt / TypeScript.
• Specialization: Data-heavy dashboards, complex UX workflows, real-time WebSocket systems, admin panels and personal cabinets over complex APIs.
• Domains: AI, fintech, blockchain, infrastructure, commercial websites, landing pages.

Skills & Technologies

• Frontend: Vue 3 / Nuxt, TypeScript, JavaScript, HTML, SCSS
• State & Data: Pinia, Zustand, Vue Router, REST, WebSocket
• AI Tooling: Claude Code, OpenCode, OpenRouter, LM Studio, Ollama, MCP servers
• UI & Design: Figma, Tailwind, shadcn/ui, Naive UI, Bootstrap 5
• Build & Infra: Vite, Webpack, npm, Git, CI/CD, Docker
• Testing & Debugging: Vitest, Playwright, Sentry, Devtools
• Workflow: Swagger / OpenAPI, Postman, YouTrack, Linear, Miro, Draw.io

Strengths

• Architectural Soundness: I choose long-term payoff solutions - strict typing, decomposition, no rushed compromises. This reduces debugging time and maintenance cost.
• AI Tooling: Not just a Copilot subscription, but my own kit - plugins, scripts, MCP servers, corporate stack integration. AI should augment the engineer, not replace them.
• Context Retention: Successfully maintain multiple large-scale projects long-term; navigate stack, legacy code, and business logic; provide accurate estimates.
• QA Mindset: I don't just produce code - I build UI anticipating how it could break. Systematic approach to edge cases and visual consistency measurably reduces UAT bug count.

Current Focus

• AI tools in development and testing
• System design
• Product thinking
