Software Architect & DevOps Consultant

Hello, I’m Kristof, a human being like you, and an easy to work with, friendly guy.

I've been a programmer, a consultant, CIO in startups, head of software development in government, and built two software companies.

Some days I’m coding Golang in the guts of a system and other days I'm wearing a suit to help clients with their DevOps practices.

Giving back to the community #

We get so much out of open source that it always feel good to give back to the community.

Like a responsible programmer, I release as open source my code that might be useful for others. I also regularly dive into codebases of other open-source software to fix what ails me, and submit my patches to the projects' owners for integration. It's a habit that goes back to 1999.

Here's a list of things I've created or contributed to:

🌳VMtree (an easy way to make ephemeral VMs) #

VMtree is a collection of scripts that turn a server into a "VM tree", on which you can quickly start up (and delete) ephemeral LXD containers. Especially useful when developing infrastructure-as-code, for example Ansible scripts.

Gitea (GitHub alternative in Go) #

Contributed project management screens, allowing Gitea to be used as a time tracker for development teams.

Security issue and workaround for Jumpcut #

Reported a security issue and provided a workaround for this great OS X clipboard history tool.

FastClick (network router with DPDK support) #

Contributed the SetTCPChecksumIP6 element to add the ability to calculate the TCP checksum for IPv6 packets (which in theory should be the same as for IPv4, but in reality it is not).

Click modular router toolkit #

Bugfix in FromDPDKDevice to correctly set the MAC header in the FromDPDKDevice element.

ParrotSec (security focused Linux distro) #

Introduced Wireguard VPN into this security-focused Linux distro.

This script provides better way to install and maintain vimrc, screenrc and bashrc and other rc files.

Commodore 64 themed web placeholder #

You can have one too! :)

It's a python time stracking tool for freelancers. Works with plain-text files for simplicity and versatility.
