martijn jacobs

Hi, I'm Martijn, a software developer and consultant based in Arnhem, NL. I have 20+ years of (web) development experience, mostly with (but not limited to) the programming language Python.

I've worked on various projects for smaller and larger companies in many roles, such as (lead) developer, consultant, educator, mentor, code reviewer, researcher, and more. As one of the founders and owners of (Four Digits) I've also gained business development and project management experience.

I'm a proponent of open-source software and the values associated with it. Furthermore, I highly value privacy and security, and I care about social and environmental impact. Current AI developments are promising, but I'm also guarded regarding consequences and use case(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 complete 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, and my current favourite container OS is Alpine Linux. Sublime Text is still my favourite editor.
