AI agents that do the work

I connect AI assistants to your systems and build agents that prepare the work, while people approve anything that touches money or customers. Co-founder of Fattly.app, freelancing since April 2026.

Services

Three things I do well

MCP

MCP servers

A Model Context Protocol server that lets Claude, ChatGPT or Cursor read and act on your API, with permissions and logs. I built and published one for Fattly (npm package fattly, hosted version with OAuth, listed on Smithery).

E-commerce

AI agents for online stores

Customer-support agents for Shopify or WooCommerce stores that answer from your own store data, say they are AI in the first message and hand refunds and edge cases to a human.

GEO / AEO

AI search audit

Why your site does or does not show up in ChatGPT, Perplexity and Gemini answers: crawlability, structured data, llms.txt, content that can be quoted, plus technical SEO and Core Web Vitals.

Prices are starting points for the basic packages; the current scope and price are always on the platform listing.

Proof

What I have built

  • MCP server for Fattly.app, published on npm (npx fattly mcp), hosted with OAuth and listed on Smithery.
  • A pre-deployment guard agent that checks every code change and returns GO or NO-GO, backed by 1,800+ tests.
  • An alert that tracks AI model changes at providers, so we hear about deprecations from the agent, not from users.
  • An in-app AI assistant and a support chat with Telegram alerts.
  • Technical SEO: 67 to 185 pages indexed by Google in under 5 weeks (5 languages); mobile PageSpeed 86 to 95, LCP 3.8 s to 1.2 s.

House rules

  • Any agent that talks to customers says it is AI in the first message (EU AI Act, Art. 50).
  • Refunds, cancellations and payments are approved by a human.
  • Answers come only from your data; anything unknown goes to a person.
  • Logs, API spending limits and error alerts in every deployment. You own the code.
