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.
From concept to $1,700+ in revenue within 3 months — 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.
