One line is enough.
I read everything and reply to anything with a real question in it — usually within a couple of days.
Every profile below is one I actually maintain. Nothing is listed that does not resolve to a real page.
Where else I exist
The same routes as above, with a little more about what each one is for.
Working with me
I work across OEM and Tier-1 boundaries, mostly on Android Automotive platforms in Germany, alongside Android application work. For roles, collaboration or a technical question, email is the fastest route — LinkedIn works too, though I check it less often.
A note on what I publish
This site carries an email address and links to my public profiles, and nothing else about me. No phone number, no home address, no CV file, no analytics and no cookies. If you need a resume, ask by email and I will send one.
