I’m a Frontend/Full-stack developer. I build fast, clear web services and Telegram bots for real business needs. I value structure, deadlines, and transparent communication. My focus is long-term partnerships and measurable results.

How I can help

    •    Websites & landing pages (React/Next.js, responsive, high performance).

    •    Admin panels/dashboards for accounting, analytics, inventory/products.

    •    Telegram bots: requests, payments, notifications, API integrations.

    •    Integrations & automation: REST/GraphQL, CRM/Google Sheets, exchange/financial APIs.

    •    Improving existing projects: refactoring, performance boosts, bug fixes.

Tech stack

JavaScript/TypeScript, React 18, Next.js, Vite, Tailwind/shadcn UI;

Node.js/Express, Python (aiogram), SQLite/PostgreSQL, Firebase (Auth, Firestore, Functions/Cloud Run);

Git, basic Docker, WebSockets, JWT/OAuth.

How I work

    1.    Short brief → timeline & budget estimate.

    2.    Scope approval and task checklist.

    3.    Sprint-based delivery with a demo at each stage.

    4.    Documentation and handover of source code.

    5.    Post-launch support and enhancements on request.

Why clients like working with me

    •    Predictable timelines and regular progress reports.

    •    Clean code and attention to UI/UX details.

    •    Bug warranty after delivery (support window agreed upfront).

    •    Clear communication: RU/UA (EN — basic), CET time zone.
