I would say my actual expertise and speciality is wiring multiple languages and processes together, automation jobs, etc. Used most are NodeJS (with lots of experience with many libraries), ReactJS (also lots of neat libraries I've found and used over the years), and Postgresql (backend), but by no means a specialist in any one language. I've also been extensively writing ABAP and SAPUI5 at my day job.

Any neat ideas requiring programming! It doesn't have to be an app or even a website, heck, I've been on a hackathon team that built a beerpong robot with computer vision to shoot ping pong balls into plastic cups!
