Ivan DoroninBots. Mini Apps. Automation.

I automate the routine so your business runs while you sleep. Telegram bots, Mini Apps, websites and CRM integrations, built end to end — from idea to deploy and support.

I think about your business, not just the code

I’m Ivan, I’m 20, and I build digital products end to end. I work with leads and sales myself, track conversion and understand how a product is supposed to make money. So you don’t get “code to spec” — you get a tool that earns.

I run the whole project: idea, prototype, development, server deploy and support. No need to assemble a team and translate between a designer, a developer and a sysadmin.

What I build, end to end

One developer instead of an agency: from idea and prototype to server and support.

  • Telegram | Instagram bots

    Any complexity: bookings, leads, payments, subscriptions, broadcasts, analytics.

  • AI agents

    They take over the routine: lead handling, analysis and process control.

  • Websites & landings

    Sites that sell and drop leads straight into Telegram — and beyond. Like this one <3

  • Web platforms

    More than landing pages: online schools with courses, business management, admin panels, API integrations.

  • Telegram Mini Apps

    Full-blown apps right inside Telegram: admin panels, CRM, games.

  • SaaS & own products

    Services with subscriptions and monetisation — from idea to first payments.

  • Automation & CRM

    Google Sheets, Apps Script, Bitrix24 and integrations. The routine goes, the order stays.

  • WPF apps

    Desktop software for Windows: inventory, point of sale, CRM, staff workstations. Fast, offline, no browser needed.

Cases, not promises

Real projects — from my own product to a platform that already earns money for the client.

AI agent in Telegram

AI copilot for solo entrepreneurs

Private project — cannot be launched
Task
When you work for yourself, staying focused is hard: messenger chats break your rhythm, while promotion and routine keep getting postponed.

An AI agent structures the incoming flow: it collects a brief from the client tailored to the business niche, puts the booking into the calendar and breaks work into clear steps with reminders to keep you focused.
Result
All admin routine and deadline control are handled in one window, without overload. The entrepreneur spends time only on the key work and personal contact with the client.

How I work

Five steps, no meetings for the sake of meetings. You always know what’s going on.

process.log

  1. Brief

    I dig into the task, the business and how the product will make money.

  2. Prototype

    You see the logic and screens before development starts. Changes are cheap here.

  3. Development

    I write the code and show progress along the way. No surprises at the end.

  4. Launch

    I deploy to the server, connect payments and integrations, test on real scenarios.

  5. Support

    I don’t vanish after release: I monitor, fix and improve.
