My name is J. Dekker, usually under the 'jdek' handle online. I currently live in the CET/CEST timezone and work for a software consultancy in the Free and Open-Source Multimedia Industry.

Personal

I enjoy exploring niche systems; making them faster, smaller, more reliable, or all at once. Also creating tools and scripts to fill various needs in my digital and offline life. Outside of technical systems minimalism is a guiding principle in my life driving my quest for efficiency and mindfulness.

As someone interested in video compression and digital multimedia in general, I also have an interest in the artistic aspect as well as the technical details of both modern and film-based photography and cinematography.

Traveling has taken me to every continent except Antarctica, and I regularly attend technical conferences in Europe like FOSDEM in Brussels, Belgium or Chaos Communication Congress by the CCC in Hamburg, Germany.

Work

Since 2019, I've worked professionally in multimedia on FOSS projects such as the FFmpeg, libx264, libx265, and mpv. My expertise lies in writing both aarch64 and RISC-V assembly for optimised codec routines; I also help maintain FFmpeg and the checkasm tool.

Previously, I worked on embedded devices across consumer, industrial and military sectors focusing on the Kernel or Operating-System levels for e-readers, mesh networking devices, and radios.
