Projects

A few things I've built end to end, from the hardware up.

Petsa

Tracks pantry products by expiration date using barcode scanning, with a straightforward manual entry flow. Android launch targeted October 2026.

Expo React Native Supabase

IoT-Based Fire Alarm System

A 4-in-1 sensor PCB with Raspberry Pi 5 networking through Firebase for live monitoring, using the Venturi effect for active smoke extraction. Best Thesis, College of Engineering.

Raspberry Pi 5 Firebase PCB Design

Environmental Monitoring Station

A commissioned multi-sensor station reading temperature, humidity, globe temperature, sound and light on a live display. I did the board design, assembly and testing; the web dashboard is built by the client. ESP32 build complete.

ESP32 PCB Design 3D Computer-Aided Design

Pico W Station Upgrade

The environmental station rebuilt around a Raspberry Pi Pico W, replacing the original ESP32 board. In progress, targeting Sept 28, 2026.
