Sean Molenaar

Anything problematic excites me, smooth sailing just sounds boring. This is why I enjoy speeding up processes by finding or creating the right tools for the job.

Here's the projects that I'm trying to brag about. Most of them are just for me to scratch an itch and aren't likely to ever grow beyond that. I still enjoy them though and they give a nice example of my skills.


Since halfway through 2018 I've been a maintainer for the Homebrew package manager for macOS. In this role I've helped ship of thousands of software upgrades for major parts of peoples workflow. In addition to keeping macOS developers' systems up to date I also lead the discourse support forum.


Made an Apiblueprint renderer in PHP based on the drafter tool by apiary. All of the existing tools were missing something so I wrote my own version. This has been used by M2mobi to replace the old docbooks since it's inception with very positive responses from both api consumers and writers.

Personal website

This website is made using the finest SDKs, in particular the contentful SDK. It serves all the data and the localization and this website is just a view using some JS, CSS and PHP.

Nextcloud news

Over the past few years I've made numerous contributions to the nextcloud projects RSS reader app. As an avid user I've implemented security fixes and under-the-hood improvements I thought were important for my continued usage. This is in my eyes how open-source should be done, everyone scratching their own itch.
