15 years in retail. Now I build the tools that sell.

Agents, websites, video and crypto tools that run in a live business.

AI engineer and creator from Izmail, Ukraine. I plug AI assistants into store chats, launch websites with payments, make trailers and short videos, and write tools on blockchains. Remote, in English and Ukrainian.

Where are you starting from?

Your store has a chat, and nobody is in it at night

An assistant on your catalog: picks products, quotes delivery, hands the order to a manager. Never invents prices or discounts.

How it runs in a live store

You need a website that works at a link, not in a mockup

From layout to launch with forms, payments and analytics. Brand colors change in three lines.

Websites

You need a video or a trailer for a launch

Frames with film references, character sheets, original music and voice, exact timing from the brief.

Video and content

You need a tool on a blockchain

Stablecoin payment links, stock gifts, stop-loss checks on an exchange. Arc, Base, Somnia, Solana.

Crypto

You are a solo pro and clients text at 11 pm

A booking bot in your Telegram in 5 minutes: clients pick a service and time with buttons, you get a notification, they get a reminder.

Why stores and small business

What I am on right now

  • Building the portfolio site you are reading now
  • Daily review of the AI shop assistant's live dialogs
  • Waiting on three open-brief decisions: a book trailer, a video intro, a syndicate website

15 years in retail and e-commerce: 10 years running an online plumbing and heating store, about 7 in purchasing for an appliance chain. So I know what buyers ask and what eats a manager's time.

Freelancing since 2024, I do the same with tools: an AI assistant in a store chat, a booking bot for a solo pro, a website with payments, a video for an ad. The first assistant runs in a store where I once sold and purchased those very products.
