Summary
🤩
Rockstar🎓
Top SchoolDave Disseldorp is an experienced owner and hands-on software engineer with 15 years focused on backend, kernel, and DevOps work from Uithoorn, Netherlands. He maintains a practical small-business perspective while contributing to high-impact open source projects—fixing bugs and hardening core components in the Linux kernel, dracut, Samba, Ceph tooling, and iSCSI stacks. His contributions emphasize reliability, security and testability: adding kunit tests, closing buffer overflows, preventing symlink race conditions, and improving initramfs and filesystem handling. Comfortable across C, system tooling and deployment automation, he combines deep edge-case knowledge with pragmatic fixes that prevent real-world failures. Unusually for a long-time owner of a local IT firm, he remains an active upstream contributor to flagship projects including torvalds/linux.
