The stuff that gets me paid. And then I move on to other things. That's why there's not a lot of ongoing open-source projects on my profile.

However, if there're some bugs or missing features in the tools that I use on a daily basis, I often try to improve them. If not via PRs, then at least by creating issues with bug reproductions.

Backend software engineering in the domains of compliance and risk assessment, payment processing and blockchain UX. And internal backoffice tooling supporting work of other company members. And then also some developer-oriented platform engineering, like my past contributions (seen below) would suggest, which in some way is also "backoffice tooling supporting work of other company members", but more hardcore.

Although my contributions are not big in terms of a diff size, I always do my best to make the chagne in the best place possible, by understanding the projects' structure and then explaining my findings in the PRs and in code itself.
