Clinicians That Code
The directory of clinicians that build software
Doctors, nurses, pharmacists and other clinically trained people who do not just use software; they ship it. Every entry is verified: a real clinician, a real, personally built artefact.
Curated from a continuously running monitoring pipeline across Reddit, X, LinkedIn and the health-tech press. Updated three times a week, automatically.
New: The Handover, our weekly five-minute briefing on what happened at the crossroads of medicine, code and regulation.
Why this exists: The 3am Nurse Test, on the bottleneck that just fell and what clinicians can build now.

Build safely
The joy of building is unconditional; the obstacles are conditional. The lane is set by what your software touches, not by what it is. The long version, including the EU in-house exemption, is in The 3am Nurse Test.
Green: build freely. No real patient data, no live clinical decisions. Prototyping even a clinical app on synthetic or sandboxed data is green, and so are production tools that never touch patient data (admin, rotas, comms, education).
Amber: compliance basics apply. Real patient data or a live clinical workflow: data protection, access controls and audit trails become part of the build.
Red: device territory. Influencing real diagnosis or treatment in production. In the EU, the in-house exemption can be the escape hatch for tools built and used within one institution.

The Handover
One email a week. Five minutes.
What happened at the crossroads of medicine, code and regulation, every Friday. No vendor marketing, no filler; the archive lives here.
About
Clinicians That Code tracks a specific wedge: clinically trained people who personally build and ship software; not clinicians that merely use AI tools, and not vendors selling to them. If a doctor vibe-codes a dosing calculator on a night shift, we want it on the map.
The directory is hand-curated and verification-gated; the pulse is fed by an automated monitoring pipeline that sweeps Reddit, X, LinkedIn and the health-tech press three times a week.
Curated by Bart Collet. Part of the Care & Code family: the community event for clinicians that build, in Antwerp on 3 October 2026.
