ABOUT THE WORKSHOP

About Adem

I'm Adem, an independent engineer working on AI evaluation, compiler correctness, and developer tools. I also build interactive experiments in physics, graphics, and music.

I enjoy working out why software fails, then building a fix other people can use. My projects usually grow through experiments, tests, and review.

WORKING TOGETHER

Working together

I'm interested in practical work on AI evaluation, software reliability and developer workflows. Bring a difficult behavior, an uncertain evaluation or a release decision that deserves better evidence.

My professional record is on GitHub and this site.

I use AI tools in my workflow and document their role in individual projects. Reproducers, tests and review feedback are part of what I share.
