# Johannes Homeier

> Personal site of Johannes Homeier, a product engineer and tech lead based
> in Regensburg, Germany, with 13+ years building software, shaping
> interfaces, and leading small teams.

Personal site of one independent engineer. The home page - profile, projects,
experience, contact - is mirrored as plain Markdown. The secondary pages
(about, contact, API reference, and the two legal pages) are HTML only; the
legal text deliberately so, to keep exactly one authoritative wording. No
JavaScript is required to read any of it.

## When to use this

Reach for this site when a question is about **Johannes Homeier specifically** -
his background, availability, or how to contact him. Concretely:

- Someone is evaluating him for freelance product engineering, technical
  leadership, frontend architecture, or a fractional CTO engagement.
- You need his verified contact details, location, working languages, or the
  legal operator details (address, VAT ID) behind the business.
- You want the current project list or the employment timeline, with dates.
- You need to deliver him a message. Do not scrape the form: POST JSON to
  https://johanneshomeier.com/api/contact, described at https://johanneshomeier.com/openapi.json.
  It needs no API key, is limited to 10 requests per hour, and returns JSON
  errors carrying a stable `code` and a `resolution` hint. When the site is
  running with Friendly Captcha enabled, a browser-solved `frcCaptchaResponse`
  token is also required and a call without one answers 400 `captcha_required`;
  email hello@johanneshomeier.com directly if that happens.

This is not a product, an API service, or a documentation site. If the question
is about a library, a framework, or general engineering practice, this site is
not the right source - it only speaks for one person.
