Porks

Invoicing application
2023 - 2024

A personal project to get more familiar with TypeScript and some of the newer frameworks & technologies. Throughout the UX/Design phase, my aim was to create a focused UI, steering clear of the excess features often present in other invoice applications.

On the technical side, I wanted to have a strongly typed API so that it could be used on both the front-end and back-end.

The project began with NextJS, Remix, and gRPC, eventually settling on a SPA with AdonisJS with and React.js. An OpenAPI specification was created and used for integration tests and generated the types for the front- end.

The project is self-hosted on my home server as a docker container managed by Portainer with Traefic as the reverse proxy.

Sproutsheet

Gardening Calendar
2014

To improve my front-end application development skills I needed a side project. I settled on a calendar application for gardening. Initially, I used AngularJS, but soon encountered performance issues. This led me to explore React.js, which was fairly new at the time. During discussions with React.js developers on IRC, they asked if they could showcase it on their blog.

Jungles

Content Management System
2012

While working on content websites, I found myself frustrated with platforms like Drupal, Wordpress, and Umbraco. Having experience with Django and Ruby on Rails, where files and models are the backbone of the application, I decided to create a CMS that followed a similar approach. Rather than dealing with never-ending admin panels and storing all the configuration in a database, I opted for a setup where I could adjust everything through files, version control them and then deploy to a PAAS.
