Fig. 1 — Typical application Featured

IoT Head-End System

A distributed head-end system for drinking-water telemetering, written in Rust. Clustering with SWIM failure detection, device delegation across nodes, a custom scheduler, persistence, and observability through Prometheus and Grafana. This is the software half of my capstone project, alongside the low-power firmware and the cellular PCB.

DS2000

A USB button box for Discord, built end to end: a Rust desktop application with Tauri, C++ firmware on the microcontroller, and a custom PCB designed in KiCad. Mute, deafen and disconnect from a physical button, with RGB LEDs mirroring the state.

Capstone project
IoT smart water metering End-to-end system for remote reading of household water meters. A battery-powered STM32L0 device counts the flow meter's pulses and reports daily over LTE-M/NB-IoT to a multi-node Rust head-end server, through a custom low-power protocol based on IEC 62056. I designed the device PCB in KiCad and characterized its power consumption on the bench, projecting over 8 years of battery life. Read the report
