about
Hi, I'm Martijn, a software developer based in Arnhem, NL. I have 20+ years of (web) development experience, mostly with (but not limited to) the programming language Python.
I'm a proponent of Open Source Software and the values associated with it. I highly value privacy and security and care about social and environmental impact. Current AI developments are promising but I'm also guarded regarding consequences and usecase(s): I do not consider it as a solution to everything.
TDD, CI/CD and DevOps are things I like to implement and automate with tools such as Pytest, Playwright, Docker, Gitlab CI/CD and Github Actions. I sometimes orchestrate full stacks with Terraform and/or Ansible.
I'm also familiar with front-end development including HTML, Javascript (TS), (S)CSS or frameworks like tailwindcss and Vue.js.
Unix based systems like Linux and MacOS are my preferred OS's. My current favourite Container OS is Alpine Linux: A lean Linux distribution with a small footprint. Sublime Text is still my favourite editor.
