Reading a Codebase You Did Not Write
A practical walkthrough for engineers joining an unfamiliar repository. Map the modules, trace how a request moves, and find the seams before you change a line.
Open the walkthroughDarwin Digital Factory is a learning platform for people who want to build software properly. Modules move from everyday coding habits through application development to architecture decisions and the IT concepts that keep systems maintainable years after the first release.
Structured tracks, written material and worked examples. You read, you build, you review what you built.
Darwin Digital Factory is a software engineering and IT academy based in Braunau am Inn. We work with people who want to understand how software is actually put together, not just how to call a framework. The curriculum moves through coding practice, application development, software architecture, and the IT concepts that sit underneath all of it.
Most of our learners arrive from one of two places: career changers who have written some code on their own and hit a wall, and working developers who can ship a feature but want a clearer mental model of the systems they touch. Both groups get the same treatment here. We start from the fundamentals, keep the modules structured, and expect you to write real code rather than watch someone else do it.
Three write-ups from the Darwin Digital Factory desk. They pair with the modules on this page: read one before you start a task, then come back when the code fights you.

Independent scaling, separate release cycles, clear ownership: those are the signals. Everything else is usually a modular monolith wearing a costume.

Suites rot when they assert on structure instead of behavior. Here is how to rewrite brittle tests without losing confidence in the system.
