About this gig

Your backend has grown for years. Releases take longer, nobody wants to touch the core, and some of the libraries are past end of life. You need to know where the real risks are before you decide what to change.


I'm a software architect working on exactly these systems, mostly Java with Spring Boot and Go. I go through your code and architecture and write down:


- which parts are tangled and why changes there are expensive

- which components run without vendor support

- which risks touch customer data or payments

- what to separate first, and what to leave alone


You get a written report your developers and your management can both read. It is short, and every finding points to a place in your code.


Basic covers one service. Standard covers one application and includes a call to walk through the results. Premium covers the whole platform and ends with a step-by-step plan, starting with the first cut that can go live within weeks.


An NDA is fine and read-only access is enough. Please message me before ordering.

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.
