  • Development of modern websites and web applications

    Web Programming
    Development of modern websites and web applications

    I create high-quality, fast, and user-friendly web applications of any complexity — from simple landing pages to full-fledged systems with personal accounts, integrations, and admin panels.

    … What I do:

    Landing pages and corporate websites with modern design.

    Web applications and services with authentication, database, access roles.

    Personal accounts, control panels, CRM modules.

    Online stores, product catalogs, payment integrations.

    Real-time systems (sockets), integrations with APIs, chats, and Telegram bots.

    Performance optimization, SEO, mobile adaptation.

    Integrations with databases, third-party services, and REST APIs.

    Full development cycle: from structure and design to deployment on VPS.

    Technologies:

    Front-end: React, Next.js, Tailwind, TypeScript

    Back-end: Node.js (Express, NestJS), MongoDB, PostgreSQL

    Integrations: REST API, JWT, Stripe/WayForPay/Portmone

    DevOps: Docker, PM2, Nginx, VPS (Ubuntu)

    Design: responsive layout, UI components, modern patterns

    Why me?

    I create production-level projects that can be scaled.

    I write clean and maintainable code structure.

    I provide complete server setup and deployment.

    I add documentation and usage instructions.

    I create websites that not only look modern — they are fast, stable, and solve business tasks.

  • Telegram bots

    Javascript and Typescript
    Development of Telegram bots of any complexity

    I specialize in creating Telegram bots of various levels of complexity — from simple chatbots to complex business systems with integrations, authorization, and process automation.

    … What I do:

    Bots with personal accounts, authorization via phone number, tokens, or CRM.

    Integrations with Google Sheets, CRM, databases, API, CSV/Excel.

    Bots for e-commerce, orders, purchase histories, call centers.

    Automation of business processes: accounting, reporting, mailings, working with price lists.

    Complex admin panels, access roles, analytics.

    Parsing, file uploads, PDF invoices, document generation.

    Bots for 24/7 operation on VPS (Ubuntu) with auto-restart and logging.

    Technologies:

    Node.js (Telegraf, grammY)

    Python (Aiogram v3)

    PostgreSQL / MongoDB / SQLite

    Docker, PM2, system services

    Working with files: CSV, Excel, PDF

    I create fast, stable, and scalable Telegram bots focused on real business needs. If you need a bot of any complexity — I can implement it "turnkey."
