At Medlas, UFDPar and Brazilian Society of Pathology, I built a national survey platform mapping pathology subspecialties across Brazil. It turns responses into statistics, charts and maps using Python, Reflex and PostgreSQL.
I wrote and maintain 271 automated tests with pytest, covering calculations, permissions, form flows and data rules. I also tested every branch of a multi-step questionnaire and created a dataset of 4,424 simulated participants to validate statistics and performance.
At Novo Olhar Optometry Clinic, I built the web system for daily operations, including appointment booking and an admin area for patient and financial workflows. I wrote 196 automated tests and deployed the system with Docker and Caddy on Ubuntu.
