For over a quarter of a century, I have been involved in programming and broadly understood IT, as an academic teacher, an employee of companies from the financial services sector, and currently a mentor/freelancer. Despite the passage of years, this subject still fascinates me, and dealing with it brings joy. Over the years, I have used many programming languages, starting (in my childhood) with Basic, through various types of assembler, in my studies I used Pascal, C/C++, Java, Ada, in my professional career I mainly used C# but also Java, Python and ... many, many others. I had the opportunity to deeply learn database systems, especially MS SQL and Oracle, but also PostgreSQL, MongoDB, ... you name it :-). Currently, I primarily use .NET + C# on the backend and React + TypeScript on the frontend.
