Built and validated a local-first Windows diagnostics platform with a native WPF/WebView2 desktop shell, persistent sessions/incidents, Event Log + WER evidence and privacy-safe support bundles.
CrashScope 1.2.0 closes at 266/266 automated .NET tests. The final integrated 1.1 performance measurement was 0.2365% average Agent CPU with 91.71 MB average / 94.58 MB peak working set on Ryzen 5 7500F + Radeon RX 9070 XT; CrashScope 1.2.0 is publicly released; 1.3 is the current development line.
Designed a local-first Windows control deck for GGUF Model Intelligence, safe runtime ownership, hardware telemetry and evidence-aware benchmarking.
Built automated update, repair and diagnostics workflows plus CI and post-update smoke validation so failures become visible before release.
Retro Game VisionComputer vision + decision system · Python / SQLite · Field tested
