Profile bio

About Mattias Hogstrom

The first programming encounter was with BASIC on the C64 in the mid 80s. As for my first formal training, it took place in the late 80s at a computer club where they taught Pascal with a monocrome ibm cp/m computer. After that I taught myself assembler, C and C++ from books. Back in those days, you only got a compiler, and a library for writing text on the screen. It was hard to do any fancy apps at all, unless you were willing to write your own low-level libraries in assembler. I wrote some low-level graphics libraries for the x86 processor but the effort I put into write the libraries took too much time from writing the real apps.At university 1995-1999 we mainly programmed under unix and in C++ with Emacs and gdb. My first job was working with the backend of a compiler. After that I worked with an implementation of automatic testing of embedded solutions (mobile phones). In 2003 I moved abroad, and adopted .Net skills, developing web sites and desktop apps. In 2009 I moved back to Sweden, and started working for my current employer with their ERP systems. First as a developer, then moving on to be the system architect. From time to time I give courses and presentations at my workplace, which is something I like to do. My personal reward is that I can refresh my knowledge and meet a lot of interesting people.I like looking at different technologies and languages. Like Objective C on my Mac, functional languages like Haskell and F#, Windows 8 Metro App development (C# and Xaml), and HTML5 and javascript. Even an almost dead language like Smalltalk, have amazingly a lot to teach newer generations.There is one thing that is very close to my heart. Debugging and Reverse Engineering.I have written debugger extensions, customized the .net runtime to do on-the-fly rewrite of intermediate code, and several test and analysis tools.

Listed skills include C#, .Net, Design Patterns, Visual Studio, and 46 others.
