About
i’m afonso — an AI engineer with a physician background, based in lisbon.
as both a physician and engineer, i build, evaluate, and rigorously test new features for Tonic Easy Medical’s AI products, ensuring clinical safety and quality at every step. Tonic’s clinical AI co-pilot reaches 200k+ doctors across 4 countries and is certified as a class IIa medical device.
my medical training and public speaking background help me bridge clinical and engineering perspectives — translating between domains and communicating technical results clearly to both audiences.
