Got my first job and was given the temporare title programmer.
He said I could choose any title (with some relevance). Opportunity of a lifetime, any suggestions?

I will be doing some deep learning, UI, general front-end and visualizations

Focus on learning and leave the titles away.
Change the word title to ego. How that sound to you?

@searchindex oh auch, a real stinger. I see it differently then you, nothing wrong with having some fun with the title.

Congratulations on your first job, that is excellent.

Or change your name to Thanos, title yourself "Destroyer of Worlds" and call it a day.

How does "prophet" sound ?

CEO, Founder, Boss

This reminds me of my first boss' user record in the system. user_id: 1, user_name: Hugo the Boss (he is also German 😃)

Be "sir," then even people higher up then you will have to call you it!
