Who am I?



I am currently a co-founder and CTO at Fablo, a start-up 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 created the ICM Networking Group at the Warsaw University, which took responsibility for the university wide-area network. I was a co-organizer of the Aula Polska initiative, promoting technology-related entrepreneurship in Poland.

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).

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 these days.


Designed and managed the creation of software systems such as STB (Set-Top Box) Devices firmware, H.264/AVC Decoder Software for Texas Instruments DSP processors, Video-on-demand System Middleware, Warsaw University Publication Database, Warsaw University E-mail system.
