Fasthosts Domain Registration System
The Fasthosts domain registration system allows anyone to find, purchase, renew and manage domain names.

I participated in the system's modernization and led further development for several years. I also introduced many modern development practices and improved performance and scalability to accommodate many daily users. Furthermore, I built primarily as a declarative state synchronization machine, implemented using an asynchronous event-driven model for performance and scale, built in C# with .Net 4.5 on the back end, and integrated with an existing PHP-based customer self-service portal and Drupal-based marketing website.

Lawyers Online Billing System

With Lawyers Online being a small company with big ambitions, an automated billing system was vital. A significant amount of manual labor is avoided by implementing paperless invoicing. Invoices are sent automatically by either email or fax and are integrated with the direct debit system to automatically take recurring payments from clients.

I designed it in collaboration with the rest of the business and developed it almost exclusively by myself. I built it with PHP on both the back and front end, but I extensively used jQuery in the user interface. Integration with financial systems was done using various proprietary XML over HTTP protocols.

Webhook Handler
An intentionally very simple and lightweight application that receives and handles webhooks. Based on a configuration file, this web service will execute the commands users specify when it receives a specific authenticated HTTP request. It is particularly useful for triggering the redeployment of Docker containers when an automated build completes on Docker Hub. It is intended for development and prototyping environments, not for use in a production environment.
