OVO Group is a leading energy technology company, committed to a net-zero carbon future and serving 5 million UK energy customers across its retail brands - including OVO Energy, Boost and SSE. I've been developing frontends for its customers and staff since 2019.

I currently work on smart meter booking for Kaluza's retail energy platform which serves the majority of OVO Energy customers. I lead frontend development on web smart meter booking for customers and a smart booking management tool used by customer service agents.

I started off at OVO Group working for Spark Energy as part of the team which looked after digital customer self-service tools. I brought my React experience to enable a project to replace a legacy Angular account management app with a faster and more usable React app built on the same PHP backend.

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.
