I enjoy making things. Here are a selection of projects that I have worked on over the years.
A personal AI assistant tied to my Obsidian vault and reachable via Telegram — running on a €5/month VPS, with everything stored as plain markdown I own.
A platform for swarm robotics research at unprecedented scale — 725+ live, real-time-controllable micro-robots, on track for 1,000. Best Demo Award at EWSN 2025.
A custom BLE-based link layer for low-power, large-scale robot swarms — TSCH scheduling, multi-gateway architecture, fast handovers. 🏆 Best Demo Award, EWSN 2025.
An IETF draft for zero-touch IoT enrollment in 3 messages — 60% faster than EAP-EDHOC. Co-author and reference implementer.

Three online developer courses on HTTP, application logging, and DevSecOps (DAST + SCA), authored for Alura — Brazil's leading developer-education platform. 32k+ students, 9.2/10 average rating.
A smart-cities pilot that put edge-AI Sentinel devices in 20 São Paulo Military Police vehicles — license-plate and weapon detection, geolocated alerts to the Police Operations Center.
Co-authored the introductory course of CodeIoT — a free, Samsung-sponsored Brazilian IoT learning platform — reaching 100k+ students.
A São Paulo automotive marketplace where customers, mobile mechanics ("FIXERs"), and workshops met in a real-time auction for car repair work. Co-founder and CTO.
