Collectionizer
A platform for managing personal collections — own product
A fully self-built platform that lets users track collections with flexible, customisable fields, including full-text search.
As a fullstack developer, I build React + Laravel web applications for businesses and organisations, and I also handle maintenance and hosting for existing sites.
Currently open for new projects.
I build custom web applications. For example to automate processes or connect systems, from data-heavy admin environments to client portals.
I provide development capacity for agencies looking for a technical partner: behind the scenes under your brand, or client-facing, whichever fits.
I maintain existing applications and sites, even if I didn't build them myself: think bug fixes, security updates, or new features. On request, I can also arrange hosting (shared or VPS).

Equipment & facilities management platform — University of Groningen
A web application for managing university equipment and facilities across departments: role-based access, a department hierarchy, a full equipment catalogue, and search.
Alongside these projects, I work for a number of ongoing clients whose projects I can't showcase publicly. References available on request.
Frond is a lightweight CMS I developed for smaller sites: a WordPress alternative without the overhead and complexity for the end user. Fast, secure and easy to maintain.
When a project needs more elaborate visual design than I can offer myself, I work with a few trusted designers.
A few examples of sites running on Frond:
I'm Arno van Oordt, a freelance developer working under the name Power-up Media. I've been in the industry for over 20 years now, more than 15 of those as a freelancer — enough to make calls independently and spot pitfalls before they become a problem. I'm social, proactive, and not afraid to share constructive criticism — traits that have only gotten stronger over the years.
