My professional experience is mostly in Internet/web development and applications derived from it with special attention towards security.
Since July 2001 I have been working as a freelancer, using PHP since 1996, and Laravel since 2017.
In that time I have seen many different companies from the inside and many different ways to build applications and infrastructure but also how to run a business. During my time as a developer I have gained a lot of knowledge, experience and confidence in being able to resolve real issues.
I believe that the most important skill of a developer used to be the ability to find appropriate information on how to solve a problem and then evaluate it for usability and correctness, although that has quite changed with the introduction of AI coding agents such as Claude Code.
After having started to develop using coding agents, I have experienced first-hand that software development is no longer what it used to be. Although I have been primarily working as a backend developer, using coding agents, I can now easily work with any frontend framework or any language, for that matter. Time to market is also hugely affected. An interesting idea that I came across related to that is that it is no longer the question how to build something, but what to build.
My objectives when developing code may differ per customer but if it is up to me I choose to deliver high-quality and secure code. Furthermore, I would really like to work as a part of a team where I can learn from my colleagues.
Currently, I'm looking for remote freelance work, ideally using Laravel, or security related, such as Technical Security Engineer, or to be part of project in a non-programming role, such as Pre/Post Sales Engineer, Project Manager, Product Owner, Scrum Master, CTO or Co-Founder.

For a local bar, I created its new website, including menu, events, DJs and an accompanying CMS, almost only using Claude Code together with OpenAI's Codex, claudex and chief (agentic AI coding tools). AI models are not yet perfect, so some of the work (such as scraping some exact data and finding appropriate images for covers and products), I had to do (semi) manually. Static hosting using CloudFlare Pages and a Worker for the contact form.
Recently I have installed picoclaw using my local AI cluster.
Furthermore, I am working on a mobile app using flutter depending fully on AI agents to do the coding.

After that I was tasked to lead the complete development of the project, for which I built a small team of developers to fix discovered issues and to prepare the application for public release.
In order to do so I implemented a development process, moving the source code into a source control system (GitLab), introducing to work with branches (GitLab Flow with environment branches), adding database migrations, dotenv-based configuration, enabling the use of different environments (such as development, test, production), configuring automated deployments and adding Docker configuration to be able as a new developer to quickly start with development.

To prepare for automated deployment based on pushes to specific branches (GitLab Flow with environment branches) I wrote an Azure DevOps pipeline to be used for testing before deployment and configured a Docker container to mimic the production server.

Student Assistant
Vrije UniversiteitAmsterdam –
As a Student Assistant for the courses Software Engineering and Computer Networks with the faculty of Mathematics & Computer Science I coached students with their pratical work for these courses. During the first course I coached five groups of about five persons. They had to implement a 'large' program as a team effort. In this case the program to implement was a route planner. The distinguished stages were: requirements specification, design, implementation (in C++) and evaluation. I also was responsible for judging the submitted results. During the second course I coached groups of one or two persons with the design and implementation (in C) of (a simplification) of the IP and UDP network protocols, and an tftp daemon and client. I was only responsible for coaching the groups.
