OVO Group is a leader in energy technology, committed to a zero-carbon future and serving 5 million UK energy customers through its retail brands - including OVO Energy, Boost, Spark Energy and SSE. I've been developing user interfaces for its customers and staff since 2019.

I currently work on smart metering for Orion, Kaluza's retail energy platform which serves the majority of OVO Energy customers. I'm part of a team which develops smart meter booking tools and services.

I worked on the My Account customer self-service UI for Spark - primarily on a project to create a React-based replacement for the legacy Angular version.

Maglabs provides bespoke digital asset management and workflow solutions to clients primarily in the retail and entertainment sectors, including major brands such as NBCUniversal, M&S, Costa Coffee and Kraft Heinz.

I worked on the initial version of MyBrandstream, a collaboration with sibling company Magnet Harlequin to provide a packaging design workflow UI to its clients. This was a brand new app built with React and a Symfony REST API to replace several legacy systems, and incorporated data integration with both an external proofing tool and a FileMaker Pro database. Amongst the things I built were performant list components with react-virtualized capable of displaying large task lists efficiently, and an Elasticsearch database enabling full-text search for tasks and projects.

I was part of a team handling site reliability and performance for legacy LAMP-stack workflow and digital asset management apps. This primarily involved handling bug reports from customers escalated from front-line support by identifying the root cause and applying code fixes where necessary.
