This project is scheduled for launch
Launch date: Friday, October 30, 2026 at 08:00 AM UTC

Matjaž Korošec is an AI product engineer with 25 years in frontend and full-stack work. On his last job he built for 12 casino brands with about 7 million players a month, and he built an AI app there that answered support questions with a narrated video instead of a call. He rewrote frontend code so pages loaded 25% faster and 30% fewer visitors left, and a popup he built tripled sales on the campaign it ran on. He works remote on your hours, and has since 2005.
Key Features
- AI features that ship: an AI app that turned support calls into a link to a narrated video
- 25 years of frontend and full-stack work: React, Next.js, Vue, Nuxt, TypeScript
- Speed: pages 25% faster, 30% fewer visitors leaving
- Conversion: a popup that tripled sales on its campaign
- Responsive since 2010, AI since 2025
- One person who checks the whole product: the look, the code and the AI
- Accessibility audits for the EU law, plus his free Tab trail tool
Use Cases
Your app was built with Lovable, Bolt or Cursor and keeps breaking: he audits it in 5 days and gives you a plain report with every finding ranked and a price for each fix. Your shop has to meet the EU accessibility law: he audits it and prices each fix, starting with the checkout if you want. A feature has been "next sprint" since spring: he builds it and ships it, AI or not. Your support team keeps booking calls: he builds an AI that answers with a link and a narrated video.
Pricing Information
Fixed price, agreed in writing before he starts. 50% upfront, 50% on delivery.
- AI-built app audit: from 1,500 EUR (critical check from 750 EUR)
- Accessibility audit: from 2,500 EUR (checkout only from 1,500 EUR)
- 1 feature, shipped: from 5,000 EUR
- Open to full-time AI product engineer roles
User Experience and Support
You talk to him directly, on your hours. You own the code. A bug in his work reported within 14 days gets fixed free.
Technical Details
React, Next.js, Vue, Nuxt, TypeScript, Tailwind, and AI built with Claude Code and Codex. His own site has a crab assistant that answers questions right in your browser with no API calls, and the site meets WCAG 2.2 AA.
