I make businesses run systematically, not on manual effort

If you have too much manual work, processes depend on specific people, or you've tried implementing something but it didn't stick — reach out, let's figure it out.

What I do

Business Automation

Your team does the same thing every day? I'll set up a system that does it without people — no mistakes, no reminders needed.

Web Applications

Want your own product but don't want to depend on third-party platforms and pay commissions? I'll build it from scratch — so clients and staff can work without instructions.

AI Solutions

I plug in AI where it actually helps — answering customers, processing requests, analyzing data. Only if it solves a real problem, not for the hype.

Refining Existing Projects

Started building something — got stuck or it doesn't work right? I'll review what you have, tell you honestly what can be fixed, and do it.

Auto-replies to reviews for an e-commerce seller

The seller couldn't keep up with buyer questions — delays were killing conversions. I built a system that reads questions on its own, checks inventory, and responds in policy-compliant language. Now replies come instantly, 24/7 — without the owner lifting a finger.

Web Application

"Pocket Psychologist" — a platform for audio practices

A psychologist was selling meditations through Telegram and course platforms — commissions ate into revenue, content had no protection. I built a custom platform: audio plays even with the screen off, access is locked for outsiders. The client got a product under full control — no commissions, no dependency on third-party services.

Telegram

Custom engine for a Telegram subscription club

Off-the-shelf bots didn't offer enough control — the referral system didn't work, client data stayed with the platform. I wrote an engine from scratch: subscription management, referral program, automatic recovery of users who didn't complete payment. The club runs without third-party commissions, and reminders about incomplete purchases bring back a portion of lost users.

HR & AI

AI assistant for hiring at a construction company

High turnover — the company was spending time and money on recruitment, but people kept leaving. I built an assistant that screens resumes on its own, conducts technical interviews, and logs results in the CRM. The manager stopped wasting time on initial screening — the system delivers qualified candidates straight to the final interview.

Frequently Asked Questions

What if everything breaks?

Everything is tested before launch. Covered by warranty per the agreement — if something goes wrong after delivery, I'll fix it.

We tried cheap developers — it didn't work out

A familiar story. I'll review what was done before me, tell you honestly what can be saved, and what's better to rebuild properly.

We don't have our own IT specialist

You don't need one. I deliver with documentation and train the team. Three months of support after launch included.

Guarantee & Support

Contractual warranty

All work is documented in detail — no verbal agreements.

3 months of support after launch

Included in the price. I keep an eye on things and don't disappear.
