Full-stack engineer. I build AI-powered products, embedded systems, and way too many side projects.
Python, TypeScript, FastAPI, React, Docker, Raspberry Pi, ESP32 — whatever gets the job done.
Currently working on: Meu Assistente IA, Tyxter Studio, LLM Factory Toolkit, MyVirtualCompany

| OrderFlow | Order management platform for service-based businesses. Quotes, receipts, customer notifications, and manager dashboards with analytics. | TypeScript, React, Node.js | 6/10 |
One-man-army at Savefarm (agtech). Built features and maintained the entire embedded software stack for precision agriculture spraying sensors running on Raspberry Pi. Computer vision, CAN bus communication, valve control, encrypted OS images — all of it.
| Project | What it does | Stack |
|---|---|---|
| Savefarm Main | Firmware for precision spraying sensors. Green detection via OpenCV (HLS segmentation), multi-nozzle valve control over GPIO, CAN bus comms with the vehicle, PiCamera streaming, curve compensation. Runs on Raspberry Pi mounted on agricultural equipment. | Python, OpenCV, PiCamera, CAN bus, GPIO |
| SavefarmOS | Encrypted Debian image for field sensors. LUKS root partition with hardware-bound auto-unlock, firmware compiled to .so for IP protection, USB/HDMI disabled. The kind of thing you build when your client wants copy protection but won't pay for proper hardware security. |
Debian, LUKS, initramfs |
| Savefarm Watering | Fork adapted for precision irrigation. Detects seedlings and triggers watering via GPIO. Timer-based valve control, PID saturation tuning. | Python, OpenCV, PiCamera, CAN bus, GPIO |
