Computer Engineer. I like products that touch the physical world: the firmware on the board, the service that collects what it measures, and the screen where someone finally reads it. Most of the fun is where two of those meet.
Three years at SENAI CIMATEC, 907 commits across 11 projects that made it to production.
The one I'd show first is the interface of a medical vacuum system: 245 commits, LVGL on an STM32H753, and a desktop Qt simulator I wrote so the screen could be built and tested without ever touching the board.
There's a power datalogger that ran two years in the field, reading meters over Modbus RTU into a cloud time-series database through a disk queue — a reading only leaves disk after the write comes back confirmed, so a dropped connection costs nothing. And a ground station dashboard for a nanosatellite, where pulling visual config apart from data mapping deleted ~2,900 duplicated lines across six screens.
Before any of that I built the first BI dashboard my department had, in Power BI with DAX written by hand. It got adopted, and someone later built a whole system on top of it.
