About Me

I am a creative full-stack web developer with a passion for UX. I take a customer-first approach and work across all the technological components to implement features that add value. I thrive in a culture of innovation and high standards and love a good discussion about how best to tackle something.

Notable Projects

Worktribe 2020 - Feb 2022

Worktribe are a product company well-established within higher education, making administration software relied on by many UK Universities. I was recruited to help maintain their mature legacy PHP codebase whilst also leading the new build of a Laravel API which will serve multiple native apps and ultimately become the replacement.

RCoA Lifelong Learning Platform 2017 - 2019

Via my role as Principal Developer at Nomensa

A bespoke application for Royal College of Anaesthetists to track learners progress toward qualifying. Many complex multi-user workflows with strict role-based permissions. I led a team of 3 devs (me + 2), full time for over 2 years to deliver and then iteratively improve my largest and most complex application to-date. Recruited to rescue the project, I inherited the codebase in a bad state and applied proper Laravel-style techniques to leverage the full power of the framework. Built in Laravel and JavaScript, test-coverage with Behat and pipeline/deployment managed through GitLab CI. Notable features included partial functionality offline via Service Worker API.

Bloodhound VR Autumn 2017

3D WebGL interface for visualising live data over WebSocket connection to the Bloodhound SSC. Delivered via contract at Zubr VR. Large JavaScript code base, deployed with Capistrano.

Channelisable Company Intranet Summer 2017

An employee benefits provider tasked me with building a news and social platform capable of being channelised for multiple companies and integrating with their current legacy system. New-build in PHP 7, Laravel 5.4. Bootstrap 3 for rapid templating. Deployed with Capistrano.

Carbon Reduction Scenario Simulator Spring 2017

After my previous rescue effort for Real World Visuals they asked me to pick up an unfinished, partly broken CodeIgniter project, pull the back-end code up to standard and get it stable and live-ready. Deployed with Capistrano.

Estate Carbon Emissions Visualiser 2017

Real World Visuals needed some help making a fledgling product fit for demonstration. Picking up where another dev left off I merged 2 tightly-coupled repos that should never have been separate and worked across the full stack to polish and standardise the codebase so that I could then implement critical features ready for client demo. PHP (CodeIgniter framework), SQLite database, RESTful API and WebGL, JavaScript, CSS interface. Deployed with Capistrano.

Open Mic Finder 2010+

PHP site with public login and private CMS. 23,000+ active monthly users. Everything you see on the site was designed and coded by me. It hosts user-generated content so I have had to come up with solutions to tackle problems with data quality, data rot, spam, duplication and abuse.

BookFetch 2017

A platform for a charitable startup. OAuth Authenticated RESTful API (Laravel 5 running on PHP 7) allows mutliple internet-enabled stock scanners (Python scripts running on Raspberry Pi) to log books. A cron task queries a public API to process the scanned ISBN numbers. Special emphasis on absolute ease of use at speed.

Poetry Pin 2016

Mobile web app (JavaScript) that uses device GPS sensor to enable users to submit poetry along defined walking routes. Profanity checker filters obviously offensive content. Tests written in PHPUnit. CMS and RESTful API in PHP.

Internal planning system for international catering business 2016

Previously built with outdated and messy PHP the system had begun to run frustratingly slow. I performed code surgery, properly normalised the MySQL database (58+ million rows) and successfully reduced report generation time from minutes to seconds. I also modified the front-end interface with tips and validation to ensure the users were inputting standardised data.

Horizon Data 2015
