Eu vou auditar seu backend legado em Java ou Go e entregar um plano de modernização

I'm Patrick, a freelance software architect from Berlin. I work on backends that have grown over many years and have become hard to release: Java and Spring Boot, Go, Vue on the front end, Kubernetes underneath. My job is to untangle them piece by piece while the product keeps running, so there is no big rewrite and no long freeze. On Fiverr I offer the small, fixed-scope parts of that work: code and architecture audits, upgrades away from end-of-life versions, and consulting calls. You get a written result you can act on, in English or German.
