I had the pleasure of working with Johannes as part of Google Summer of Code in 2020 and 2021 working on LLVM. He mentored me and many students over the years.

I remember in 2020 he would meet with us at 7AM his time to accommodate every student he was working in different parts of the world (Turkey, Greece, China, Japan iirc), I was the one from Turkey.

I had Coffee with him and his wife few months back. He was so full of life despite everything.

He touched the lives of many people. What a great life lived despite being so short.

It shares a personal anecdote illustrating his exceptional dedication to mentoring students across international time zones.
