From Chore to Choice: Build Automation Done Right

Developer. Author. Speaker.

Hi, I am Wolfram. And I help you with your CI/CD pipelines and build automations.

There’s no doubt about it: Large projects, in particular with a large code base possibly exceeding 100,000 lines, are challenging. Maybe you know this situation all too well – after having worked on your code for several years you may have adopted different paradigms. Requirements have changed and introduced conflicts. Parts of your code are called “legacy” and decisions had been made for “historical” reasons.

Wolfram Schroers Portrait

While working on my PhD thesis I needed to analyze and extend a program written by a research group over the course of several years. The program was working well, and I was able to use it as a foundation for my own project. A few years later I was working on a different project and again had to deal with a code-base that had evolved for many more years. But this time it was remarkably different: build scripts failed randomly from one version to the other, it was unclear how to extend it, and subtle bugs led to failures that were very costly and hard to track down.

Seminar with Wolfram

After having worked on several projects like this I have started to see patterns. I have learned how to write effective documentation that gets read and applied. I have seen how identifying the tough spots and gradually refactoring your existing code base can help you address many of these issues. I have also become a strong proponent of continuous integration and continuous deployment and have experienced how these practices lead to more confidence in your code and facilitate the refactoring process.

Over the years I have been in various projects adopting different paradigms and worked with multiple technologies. These days I prefer to work with Python for everything related to scripting and task automation (with a little bash on macOS and Linux systems), Clojurescript with re-frame for web applications (Clojure for the backend), and Objective-C and Swift for iOS.

If you’d like to know how to improve your CI/CD pipeline, your development workflows and your software architecture, I’d love to help you.

Philosophy of Teaching Statement

While working in Academia I have based my teaching efforts on a couple of principles and wrote these down in my Philosophy of Teaching statement. I still believe in these principles, so I keep this document.
