About

This is my personal blog on profiling, debugging, and the occasional non-programming content. I started at the end of 2022 to write blog posts regularly as part of my work in the SapMachine team at SAP SE, spreading the word on topics like profiling or debugging.

I’m trying to write a blog post every two weeks: These blog posts cover usually profiling related topics from my current work. You find here many posts related to testing profiling APIs, OpenJDK profiling internals, and general profiling topics, as this is my current area of expertise.

If you like this content, please spread the word and keep reading. I’m happy for any suggestions, questions, or criticism.
