I, Marcin Juszkiewicz, apply for MOTU.

Who I am

• Debian user since 2000 year (m68k, x86, amd64)

• OpenEmbedded developer since 2004 (arm, x86, mipsel)

• OpenZaurus developer since 2004

• OpenZaurus release manager 2006-2007

• Ångstrom developer since 2006 (arm, x86)
• Maemo developer since 2007 (Nokia 770/n810/n900)
• Linaro developer since 2010
• Ubuntu user since 2010 (amd64, x86, armel)
• Ubuntu developer since 2011 (armel/armhf cross compiler with PPU rights)

I am working with embedded ARM devices since 2004 when I bought my first LinuxPDA (Sharp Zaurus SL-5500). Since then I was one of main developers of OpenEmbedded build system, contributed a lot to OpenZaurus distribution (released last few releases, maintained security and bugfix updates repository for them), did lot of UI tweaking for OPIE applications.

Experience with building software and packaging is one of my strong skills.

My Ubuntu story

Started using Debian in 2000 on my Amiga. Then moved to x86 land and stayed with it. Maintained "rox-filer" outside of Debian for nearly two years (then ended using it and someone other took it). Packaged "tex-skak" for friend and got it into Debian (gave maintainership for someone else).

I am using Ubuntu since April 2010 due to my move to Canonical. Before I used it only in virtual machines or on external servers - mostly for checking does OpenEmbedded and Poky Linux build systems works properly under new Ubuntu releases.

Around May 2011 I got PPU permissions for my packages containing armel/armhf cross compiler which I maintain since June 2010. During last two years I had my fingers in many packages from main and universe mostly during ARM porting jams organized weekly by Linaro Developer Platform team (which I am part of).

My involvement

As Linaro developer I am working on cross compilation support in Ubuntu. Most of my work is related to toolchain components (binutils, eglibc, gcc, linux). Due to fact that I am working on ARM related things I apply for access to whole 'universe' archive.

Examples of my work / Things I'm proud of

Endorsements

As a sponsor, just copy the template below, fill it out and add it to this section.

Marcin is fun to work with, he seriously cares about packages he had sponsored and is very responsive to bugs. His coding and packaging is good and he surely qualifies for becoming a universe maintainer (beyond the packageset he is already allowed to upload (i.e. the gcc crosscompilers he maintains)) -- ogra

Marcin has been fixing quite a few packages across Universe and Main during the Linaro FTBFS Jams. He'd be even more effective in his work if he uploaded the changes themselves. Also others would be relieved of having to sponsor so many fixes on his behalf - janimo

General feedback

Marcin does great work fixing bugs, ARM-related bugs seem to be his speciality. He'd be a great MOTU.
