Rockstar🎓
Top SchoolCharles Bissonnette is a Principal Software Engineering Manager with over 10 years of experience building high-impact developer tools and design experiences at Microsoft, where he leads the Visual Studio Client Experience UI team from Redmond. He specializes in XAML visual diagnostics, Hot Reload, and cross-platform designer tooling spanning WPF, WinUI, UWP, iOS and Android, and has grown a small core team into a 12+ cross-division group driving unified diagnostics across Mac and Windows. A pragmatic architect and hands-on engineer, he has driven major reliability and performance improvements (including a Surface Isolated Architecture for the XAML Designer) that materially boosted NPS and CSAT. His contributions extend into the Roslyn open-source ecosystem, integrating Visual Diagnostics with LSP and debugging services to enable richer Hot Reload scenarios. Known for bridging product strategy with deep engineering, he combines long-term platform stewardship with a knack for creating developer-facing infrastructure that retains and grows .NET users.
