Available for projects — replying within the hour

AI-fullstack developer. Telegram bots, web apps, Python automation.

Done end-to-end — from brief to deploy in days, not weeks. Modern stack with Claude as a co-author, so I ship faster and cheaper than classic studios.

Services

What I build

Six areas, each with real shipped projects and predictable timelines.

Telegram bots

From simple FAQ flows to shops, admin panels and CRM integrations. Aiogram 3, webhook or long-polling, DB, queues.

AI-fullstack in action

Live cases you can click through right here. Real backend, real auth, real animations — not a Figma export.

Storefront/cases/orbit

ORBIT

Sneaker resell marketplace

Concept site for a verified sneaker resell marketplace (Nike, Jordan, Adidas, Yeezy, Balenciaga): catalog with live-looking market data (last sale, lowest ask, 7-day delta), product page with exchange-style UX and per-size ask grid, working cart with localStorage, JWT auth with email-code verification via Resend, and a full checkout flow ending in a demo notice. iOS Liquid-Glass surfaces throughout.

Restaurant/cases/verde

Bistro Verde

Restaurant landing with table booking

Concept site for a restaurant: cinematic hero, an about block with the venue's story and perks, a menu with category filtering and dish badges (hit / new / spicy), promo offers, a testimonials slider, contacts with a map, and a table-booking form with validation and a success modal. Burger menu, scroll-spy nav, reveal-on-scroll and a back-to-top button.

Nimbus

Day-by-day forecast for any city

Weather app: search a city, see current conditions (temperature, feels-like, humidity, wind, pressure) plus a day-by-day forecast — pick any day to see its chance of rain, humidity and wind. Background reacts to the weather and time of day, search history in localStorage, geolocation, light/dark theme. Data flows through a server proxy to OpenWeatherMap, with the key kept on the backend.

Stack

What I work with

Not locked into one ecosystem. Most-used below. If something you need isn't here, I'll pick it up for the project — AI tooling dramatically shortens the ramp into a new stack.
