Cláudio Tereso

I'm from the Spectrum generation. I started copying programs from books so I could play them when I wasn't even 10 years old. From there, programming my own programs was a leap. As a teenager I did programming work for university students and when I started working it was in programming.

My interests changed and I entered the area of databases, SQL programming and network administration, areas in which I obtained several Microsoft certifications. Along the way I also published the books, by the Portuguese Editor FCA, "Local Networks in Windows 98 & 95 - Complete Course" and the corresponding update for the hated Windows Me.

I now work with SQL Server, Power BI, Azure and related Microsoft technology. I'm also having some fun with Python.
