Who am I?

Hardware Hacker

I enjoy building things. I design and build electronic devices, usually involving some sort of microcontroller (TI MSP430, Freescale Kinetis L and K, based on ARM Cortex M0+ or ARM Cortex M4 cores). I also do analog and mixed-signal projects.

Software Developer

Contributed to a number of open-source projects, including INN (news server), Linux kernel, CMU Common Lisp (CMUCL), XEmacs, Weblocks. I regularly write software, mostly in Clojure, C, Perl, and various dialects of assembly (x86-64, ARM Thumb-2) these days.

Entrepreneur

I am currently a co-founder and CTO at Fablo, a company implementing intelligent search and recommendation engines for e-commerce. Previously, I co-founded Sentivision (IPTV software and hardware, company grew to >45 people and took an investment from SONY). I created RG Studio, a software development and consulting company (later sold). I also created the ICM Networking Group at the Warsaw University, which took responsibility for the university wide-area network.

Leader

That is how I look as a serious consultant with a correspondingly serious hourly fee.
