I'm a Belgian Linux systems engineer living in a Bulgarian village. I have worked with Linux professionally since 2004.
My operating model is simple: I use things, find bugs, and fix them when I can. That has taken me through Linux kernels, embedded systems, networking stacks, Wi-Fi drivers, firewalls, self-hosted infrastructure, and rather a lot of upstream patch submission.

Ranked by commits, with merged pull requests as the tie-breaker. Both are shown because commits better represent projects whose development predates or lives outside GitHub, while pull requests still capture work that was squash-merged. The numbers overlap and are not added together. Neither metric captures older mailing-list and maintainer-applied work such as my madwifi contributions, or work living on other forges.

In 1999, after visiting Media Planet in Mechelen with my uncle, we stopped at a computer shop and he bought me a boxed copy of SuSE Linux 6.2—a pile of discs and several manuals. That was the start of the rabbit hole.
| Year | Down the rabbit hole |
|---|---|
| 1999 | Installed SuSE Linux 6.2 and started taking computers apart figuratively as well as literally. |
| 2001 | Ran my own mail server on a free nickname.yi.org subdomain. |
| 2002 | Connected through an IPv6 tunnel and registered linux-ipv6.be, inspired by linux-ipv6.org and the USAGI project. I've been on IPv6 ever since. |
| 2004 | Started working with Linux professionally. |
| 2005 | Started testing and debugging the ipw2200 and madwifi wireless drivers, and helping users in #madwifi and #ipw2100 on Freenode. |
| 2007 | Started using OpenWrt; my first upstream OpenWrt contribution followed in 2010. |
Somewhere in there were IRC servers, eggdrop bots, and days skipped from school to write an iptables firewall script. Linux led to networking; networking led to embedded systems; using all of it led to finding bugs. The loop is still running.
I'm available for freelance work—from quick fixes and one-off projects to longer engineering engagements. If you have an interesting problem, ask; work is contracted through Adlevio.
For open-source conversation: stintel on Libera.Chat and OFTC, or @stijn:tintel.eu on Matrix.
If my upstream work saves you time or keeps your infrastructure running, you can sponsor it on GitHub. Sponsorship buys me more time for open-source work that would otherwise compete with paid projects.
