I take the hard part. You relax.

I’m Alexander, a Python backend developer. I take on any development work: integrations, bots, CRM, APIs, websites. I work in stages and show you the result after each one.

What I do
Photo coming soon

I work directly with clients and own the whole project: from untangling the task to launch and support. I write tests, estimate honestly and flag risks up front.

A short intro video is coming here

Work I take on

What I have built

I don’t name clients.

Instagram Direct → CRM connector

Task
Instagram Direct conversations had to land in the client’s CRM, and managers’ replies had to go back to Direct.
What I did
A separate service between Instagram and the CRM: messages and attachments over a Kafka queue per the CRM’s contract, media in S3, state in PostgreSQL, tests.

Details and demo

Paid club bot: Telegram and MAX

Task
Sell subscriptions to a private club without checking payments by hand.
What I did
The bot takes payment, grants access to a private channel and tracks the subscription term. Then I ported it to MAX.
  • Python
  • aiogram
  • payment API
  • PostgreSQL
  • Docker

Telegram chat monitor

Task
Never miss the messages that matter across a large number of chats.
What I did
The service reads chats in real time, picks out matching messages and sends them to a separate feed with a draft reply.

This website

Task
Show my work so it makes sense on a phone in a minute.
What I did
A static site on Vite without heavy libraries, an interactive React demo, two languages, my own server and HTTPS.

In stages, with a demo after each

  1. I untangle the task

    I ask questions, write down the scope and split it into stages with a clear result.

  2. I build a stage

    Code with tests, no surprises. If something blocks me, you hear about it right away.

  3. I show a demo

    After every stage you see a working result: a test environment or a screen recording.

  4. I launch and support

    Deployment to your server, a short guide, fixes after launch.

Describe the task — I’ll reply on Telegram

Two lines are enough. I’ll tell you how I’d build it and where to start.
