I'm makingscalable fundraising support for The Big Give,
an app for festivals & some dubious electro music
Sep 2018 — Present
The Big Give provides a platform for matched fundraising, bring charities together with generous pledgers and donors whose contributions can be doubled.
While helping inform work on a new platform, I've also been retrofitting DevOps best practices to a large legacy codebase, dating back over 10 years with significant technical debt. Building practical improvements on this codebase with limited time, we've made it suitable for an emergency appeal in response to the Indonesia earthquake and tsunami, and the 2018 Christmas Challenge.
I've spearheaded many security & performance fixes and moved apps from a "snowflake" server with a limiting scaling approach to a containerised solution utilising Docker and AWS's Elastic Container Service. Test apps are now properly isolated, apps behave consistently across environments, and almost all AWS infrastructure is defined as code and managed with Terraform.
I've run end-to-end load testing and arranged independent security tests to ensure the coming campaign runs smoothly, can handle large traffic spikes and keeps stakeholders' data safe.
Success at School is a platform that connects students to employers and provides career & study advice.
Initially 2014 — 2016 and resuming over the past few months, I've been the primary developer improving and adding to the site's existing Symfony codebase. In 2018 I've focused on security and modernising the system's infrastructure & deployment processes.

My role at Comic Relief focused on Payment processing, Identity APIs and Giving Pages. I worked on the ongoing transition of these to microservices, and intelligent front-end journeys built with reusable React components.
I supported a move to Cloud Foundry and 12-factor apps that are run with Docker during development, used Terraform to manage supporting AWS services, and helped configure new Concourse CI pipelines for several projects.
In 2017 we launched year-round Giving Pages, allowing fundraisers to collect sponsorship at any time on a convenient platform, without losing any portion of donations to third-party fees. The system's designed to support quicker addition of specific campaigns like Sport Relief 2018 too. The Identity and Payment APIs supported the Sport Relief steps app and are tested at scale to handle the massive load spikes of the annual campaign.
The Payment service I worked on leveraged Omnipay to support multiple payment service providers, while offering a common interface that could be shared across Comic Relief sites that need to take money. I also contributed to a new open source Omnipay adapter for Worldpay's Hosted Corporate Gateway, allowing Comic Relief to process donations reliably at higher volumes.

Hour of Writes is a weekly creative writing competition. Throughout its development I've worked with several parties to implement a carefully refined design and add features to our initial prototype.
I wrote the live site's server-side code and most front-end scripts & CSS.

I prototyped new features and refactored existing code, as well as writing components for a new bespoke framework to form a basis for future sites.
I delivered features successfully, and optimised database use to speed up some key queries by orders of magnitude.

I was often the main developer on hand supporting & developing a network of recruitment sites for the arts, the largest with 300,000 active users.
I improved database use to cut the biggest site's server response time by over 50%, and led a major database conversion to fix a long-standing text encoding problem.
I consulted with staff to build a more intuitive interface for employers to manage audition slots, and a redesigned newsletter which displays well in all common email clients.
