Website Made with ❤️ Focus: Legacy → Durable Repo language

Hi, I'm André. I help teams turn “grown & fragile” systems into calm and predictable ones — with clear risk assessment, robust interfaces, and small, verifiable steps. This repository is simply the developer’s view of my website.


What’s in here

  • Homepage & copy – the content you see online.
  • Case studies – short, straightforward write‑ups from real work.
  • Contact – if it’s a fit, we’ll find the next sensible step.

No buzzword fireworks. No glossy marketing. Just substance: problem → approach → outcome.


Selected cases

  • Pricing logic consolidated – fewer edge cases, clearer rules, easier maintenance.
    /cases/preislogik-konsolidiert.html
  • Database load reduced, query times halved – performance where it matters.
    /cases/datenbank-entlastet-query-zeiten-halbiert.html
  • Microservice stabilized under load – made failure modes visible, then neutralized them.
    /cases/microservice-unter-last-stabilisiert.html

Find all pages in /cases.


How I work

Understand first, then change. I start with a crisp diagnosis, prioritize by impact and risk, and deliver in small, traceable releases.
You’ll always know what I’m doing, why, and how it helps tomorrow.


Who this is for

  • Your legacy code carries the business and stability beats hype.
  • You need migration (often towards Go & robust APIs) without downtime.
  • You value honest assessments and predictable delivery.
