My name is Przemysław “Czajnik” Węgrzyn, and I’m a professional software developer. Welcome to my blog!

I was born in the late 70s. Like many software developers of my generation, I started my programming journey with BASIC programs on 8-bit computers. My first computer was a Commodore Plus/4 or Texas Instruments TI-99/4A (after all those years, I can’t remember anymore, which one was the first). I’ve written software professionally since the late 90s; currently, my professional focus is mostly on low-level programming, embedded systems, and web application back-ends. Over the years, I’ve gained experience with different technologies and programming languages such as Clipper, Pascal, C, Java, and Perl, to name a few. These days I use Python most of the time, also I’m an aspiring Rustacean . I love open source software, trying to contribute various fixes, if time permits.

I enjoy reverse engineering a lot. My most notable achievement is a publication titled Looking Inside the (Drop) Box , which I had the pleasure of co-authoring with my friend Dhiru Kholia. He presented it at the WOOT’13 conference.

I’m also an electronics hobbyist, interested mostly in embedded systems, audio, DSP, and FPGAs. I became passionate about retro-computing ever since I stumbled upon my broken Philips VG8010 in my parents’ attic a few years ago. I’ve loved fixing and collecting retro stuff since then.
