changemonitor.io

• Native iOS and Android. Swift & SwiftUI on iOS, Kotlin with Jetpack Compose on Android — no cross-platform compromise, both built by me.
• Built on open source. A clean, native client for the open-source changedetection.io (30k+ stars) — plus code I contribute back upstream.
• Backend in Python. The heavy lifting — fetching pages, diffing, alerting — runs server-side.
• From first concept to release in the App Store and Google Play — all by me.

Open source as the foundation, a product around it. It shows I don't just find my way around an existing codebase — I build a working product on top of it, and keep it running.

The full story — platforms, open source and client work — is on the homepage.
