I have been freelancing since early 2026. Before that, I spent four years as part of a team building and maintaining an application used every day in finance and insurance, with sensitive data and regular production releases.

Selected work

Document extraction platform
Applied AI

Document extraction platform

For an organisation in the healthcare sector. Heterogeneous reports come in (PDF, scans, spreadsheets), OCR and LLMs pull out the expected variables, anonymisation sits inside the pipeline, and a human reviews every extraction before it reaches the database. Vector search and a conversational assistant run on the anonymised content.

Qorus community platform
Web applications

Qorus community platform

Four years on a team, on an application used daily across finance and insurance: community spaces, member directory, content and event publishing, admin back-office. Sensitive data and regular releases.

Site for a recording artist
Site & CMS

Site for a recording artist

Releases are sorted by content type (albums, videos), and each page points to the streaming platforms. The artist publishes releases and updates the links from a headless CMS, without going through me.

03
Build
