How I got here, in four lines.

  1. 2018

    Joined AirLST, in Munich, as a frontend developer

  2. 2021

    Stayed at AirLST, remote from Argentina

  3. 2024

    Started building with AI agents

  4. 2025

    Finished at AirLST and went out on my own

  • 7.5 years of frontend
  • 1000+ event pages
  • Own projects with a live demo

Where I worked

Frontend developer at AirLST (event technology, Munich), from June 2018 to November 2025. I built each event's site to order: registration form, agenda, hotel, speakers and venue.

1000+ event pages for AirLST clients such as Mercedes-Benz, Netflix and BioNTech.

  • MERCEDES BENZ
  • AMAZON
  • NETFLIX
  • DISNEY
  • ZALANDO
  • DISCOVERY
  • BASF
  • AIDA
  • BIONTECH
  • THE VOICE GERMANY

How I work

Four things I do differently.

  1. Demos you can try.

    Every commercial demo runs in simulated mode: you complete a checkout, generate a report, trigger a webhook. Nothing to clone, no keys to set. The AI demos accept your own key if you want the real model.

  2. The real time, written down.

    Every repo has a public BUILD_LOG.md with how long it really took. No "made it in two hours".

  3. I build with agents, and I say so.

    I direct the AI to write the code: I decide what gets done and I test it. In the bigger projects, like Cumbre, there are automated tests with Vitest and Playwright.

  4. Public code.

    The projects are on GitHub, with their history. You can see how each thing was put together.

About me

Martin Minghetti, black and white portrait

I started in 2018 as a frontend developer at AirLST, an event technology company based in Munich. I built each event's site to order: the registration form and the pages with the agenda, the hotel, the speakers and the venue. That came to more than 1000 pages over seven and a half years, with Vue and Nuxt. I lived in Germany until 2021 and then kept working remotely from Argentina.

In 2024 I started using AI to build, and that is how I work today: I direct Claude Code, which writes the code, and I decide what gets done and test it. I finished at AirLST in November 2025 and since then I have been making my own projects, with demos you can open.

I live in Bariloche, in Argentine Patagonia. I have European citizenship (Iceland). I speak Spanish and English, and a little German and Icelandic. If you want us to work together, message me.
