Citizens Advice
Citizens Advice helps millions of people a year with debt, benefits, housing, consumer and energy problems. Casebook is the Rails application its advisers use to do that work: every client, every case, every appointment, across the national network. I joined the engineering team as one of several senior developers and worked on the core of it.
Johnson & Johnson
During the ECP Congress 2025, Johnson & Johnson needed a way to bring their precision medicine story to life on the exhibition floor. Healthcare professionals would be passing through quickly, the experience had to attract, educate, and track engagement, all without depending on venue Wi-Fi or cloud infrastructure.
Confidential (healthcare)
I built a serverless webhook service that delivers real-time conversation events to each NHS trust's own systems, handling encryption, authentication, concurrent delivery, and automatic retries.
Johnson & Johnson
For Johnson & Johnson Medical Affairs at a major international medical congress in 2025, I built an interactive presentation kiosk that works with no network at all, and still hands the team a full picture of what visitors looked at, for how long, and how far they got. The fourth build for the same client team, across three congresses.
