I write about real engineering problems — from shipping paid iOS apps to building voice assistants on Raspberry Pi. No fluff, just code, architecture, and lessons learned from shipping actual products.
The complete story of building, launching, and supporting Pwnagotchi Companion on the App Store. Covers everything from SwiftUI architecture to App Store review pitfalls.
A technical deep-dive into the real-time communication layer of Pwnagotchi Companion. How I built a WebSocket server in Python, implemented Core Bluetooth on iOS, and kept everything synchronized across devices.
Local, private, and fast — how I built a KITT-inspired voice assistant using Porcupine wake-word detection and Rhino intent recognition, all running entirely on a Raspberry Pi Zero 2 W without sending a single word to the cloud.
