Hi, I'm Ulysse.
I design PCBs and write the firmware that runs on them.
MS in Electrical and Computer Engineering at Carnegie Mellon, graduating December 2027. Looking for a Summer 2027 internship in firmware, embedded or hardware engineering.
Personal projects
Medistrib: a pill organizer filling robot
A robot that fills patients' pill organizers, from a 6-month maker project at CentraleSupélec. I wrote the firmware and designed the hoppers and the belt carriage. Graded 20/20.

Tornyol (YC F25)
Hardware Engineering Intern · Paris · May to August 2026
Tornyol is a seed-stage startup building small autonomous drones that intercept mosquitoes. I worked on the drone's electronics for the summer. The boards are confidential, so the photos here are Tornyol's public ones, not my boards.

22 × 22 mm drone flight controller
A 6-layer Betaflight flight controller around an STM32G473, with four custom ESCs, that runs on a LiPo or on supercapacitors.
20 A supercapacitor charger
A BQ25820 charger with an op-amp cell balancer and my STM32 firmware. Ran 20 A on a 1S pack and charged the 2S flight pack at 12 A.
VL53L9CX ToF bring-up and lidar flight model
Brought up a VL53L9CX ToF sensor on an STM32N6 and retrained a GRU flight model's input layers for it: 90% obstacle avoidance in simulation.
Withings
Two internships · Paris · September 2024 to July 2025
Withings makes connected health devices: watches, scales, sleep trackers and an at-home urine lab. I interned there twice, first in industrialization on a production line, then in R&D on a smartwatch.

Low-power snoring detection on a smartwatch
Audio ADC drivers and a duty-cycled wake-on-sound pipeline that cut the feature's battery cost from 15 days to 1.7 on a 30-day watch.
Production-line vision for U-Scan
Python and OpenCV defect checks on a Raspberry Pi station, deployed on the production line in China, then a TensorFlow Lite autoencoder back in Paris.
