About Me

I’m a full stack developer with nearly a decade of experience building applications with React, Ruby on Rails and other web technologies. I started my software development career ten years ago with Wordpress, jQuery and backbone.js. Five years ago I started doing backend development using Rails. More recently I started building my own SaaS product using Node.js. I have worked on teams of various sizes, using variations on SCRUM and Agile development processes.

I care about building software with an emphasis on readability and maintainability. I have recently returned to Canada after spending 6 years in Australia and am currently available to join a team in Edmonton or any remote team. I am comfortable working independently, in a team or remotely. If you would like to get to know me better please contact me through the options below:

Employment & Education

  • Software Developer at Two Red Kites

    February 2019 to October 2019

    I worked on numerous projects for smaller businesses and organisations. I regularly communicated with clients to capture their requirements, assess the scope of the work they requested and designed solutions for their specific business needs. A large portion of my work focused on enhancing the look and feel of older applications. I also dealt with maintenance items such as fixing bugs. The majority of my work was focused on Ruby On Rails applications with erb templates, jQuery and Bootstrap.

    I became very familiar with many ruby gems used for rendering pages server-side such as Formtastic, Cocoon, and Administrate.

  • Developer at Genie Solutions

    February 2018 to December 2018

    I helped build a medical practice management cloud SaaS product using RESTful APIs and a React.js user interface. I worked on the team responsible for the invoicing modules and integrations with third-party services like PowerBi. I became familiar with the nuances of end-to-end testing strategies using Cucumber and Capybara. I learned communication strategies to help me advocate for the adoption of Continuous Deployment and other good development practices. Through the opportunity of brown-bag presentations, I introduced many of my colleagues to design patterns I had learned at my previous workplace.

    I took initiative in identifying technical debt that was significantly slowing development of invoicing modules. I drafted a comprehensive report for the product owner explaining specific problems with the relevant modules. I used static analysis tools to quantitatively support my argument and chartered a strategy to incrementally improve the relevant code in preparation for new features to be added.

  • Software Engineer at everydayhero

    September 2014 to November 2017

    The team at everydayhero was large with many mentors available to teach me about various design patterns and practices to build high quality software. We built Single Page Applications (SPAs) using cutting edge tools such as React.js and Webpack. The backend for these applications were Ruby on Rails applications with a RESTful JSON API. The interfaces we built were used by charity administrators to manage their campaigns.

    We emphasised comprehensive testing and test driven development using unit tests and end-to-end feature tests. This was done using Cucumber and Selenium web-driver as part of our continuous integration (CI) workflow. I also made contributions to the reporting application built with Elixir to deliver reports to charities about their donors and donations.

Concepts were explored by designing a methodology and process that would then be carried out to completion. In presenting the art the experience and knowledge of viewers was assessed and considered to ensure the concept was conveyed in a meaningful way
