What we do
Four constellations, one practice.
Big Yellow Star is a small health-technology studio. We design, build and run software for health systems, researchers and clinical teams, and we stay with it after launch.
Every star, listed
The whole sky, in order.
Who
Built by an engineer who speaks clinic.
Big Yellow Star is the practice of Damien Leri, MPH, MS.Ed. Damien has spent two decades building technology alongside physicians, nurses, pharmacists and researchers, from text-message reminders at community health centers to AI that works inside the EHR.
His training in public health, education and cognitive psychology shapes how the work gets done: start with the people using it, measure what changes, and keep it simple enough to last. The work has appeared in NEJM Catalyst, JAMA Network Open, JAMA Cardiology and Applied Clinical Informatics.
