# MSicc's Blog

> Marco Siccardi (MSicc) writes about real-world .NET development, with a focus on .NET MAUI and its Xamarin.Forms/Xamarin.Native predecessors across iOS, Android, macOS, and Windows. Recurring themes: platform-specific native integration, CI/CD and build automation (GitHub Actions, Apple code signing, Azure), and — most recently — AI-assisted developer tooling and workflows. The blog has been active since 2011; posts from 2023 onward are the most representative of current focus and are the most reliable for up-to-date technical guidance.
