I help build products for companies that do amazing things on the web, from web applications to powerful backend systems.

I've worked with Ruby on Rails, MySQL, ASP.NET MVC 5, Amazon Web Services, Objective-C, and Knockout.JS to help deliver modern role separated applications for mobile platforms and the web. I believe in skinny controllers and zero divide between your API and frontend.

I want to work on applications that push the world forward, products that people love and enjoy using. Products should have a prupose in someone's life and it should not be a burden on their minds, applications that people dread are slowly dying and being replace with products built by people that care. People and software, engineered to work together.


In my short break between my next job I'm working with a local startup to build their first prototype from scratch. Powered by ASP.NET MVC 5; this web application utilises workers for powerful and reactive metric calculation and data collection, frontend D3 charts for rendering of metrics and a complete continuous integration/deployment pipeline for quick turnarounds.

I've worked for Discovr helping build their backend API application for the iOS client. I developed techniques for the discovery of new tracks being first played on radio, artist content from Facebook/YouTube and blogs as well as helping streamline approval of artist pages. During our launch efforts I helped track down and reduce troublesome MySQL queries.

Prior to that I worked with enterprise and consulting companies to deliver web and mobile applications for the health and risk industries using a selection of Rails, iOS and ASP.NET MVC.

In my earlier years I worked for Rummble building their new Facebook API application and integrations, while in London I learned the value of startups.

I've mentored at RailsGirls, participated in GovHacks and spoken about Ruby on Rails.

I enjoy consuming music.
