Reviews

Our managers used to spend 2 hours a day copying data from the WB seller portal. Now the profitability report opens with one click. Paid back in a month.

★★★★★

We migrated from Google Sheets to a proper database. The full order extraction from 4 accounts used to take 20 minutes — now it is 2-3. No more API throttling.

★★★★★

Tailored ERP for my construction business, exactly as I asked, no bloat. Estimates, acts, contracts — all generated with one click. Runs on a Raspberry Pi, payback in a couple of months.

Hi, I am Alexey

I build business automation since November 2022. Over this time — 20+ projects: from Excel macros to CRM systems with marketplace integrations.

How I work: tell me the task, I clarify the details, then send a written spec with a fixed price and deadline. No long calls, no multi-page proposals.

Prototype on day 2-3 — you review it and tell me what to adjust. I deliver the final version with documentation and short videos for your team.

Message me on Telegram or submit a request below. I reply within a day.
