I did try to work for opensource company, but strangely none of them accepted .NET as an acceptable experience. So I had to either find an entry-level Java position, and cut my paycheck by half, or continue to work where I do while changing things from the inside.

I already managed to introduce some open-source tools here and there (we now uses DBeaver instead of SSMS, Insomnia instead of Postman, among others), and intend to continue for as long as I can.

As for the appointment, in about 70 years, according to the current life expectation.
