- AnomalyDetector (pure domain): detects odds-flip pattern from live snapshot timelines using implied-probability vectors (p=1/rate, normalised), flip score = max(|p_post−p_pre|), gated by both threshold AND favourite-changed test - SuspensionInterval record: typed pair of (pre, post) OddsSnapshot bracketing a gap - AnomalyOptions POCO (Application layer): bound to Anomaly:* config section with four fields (SuspensionGapSeconds=60, OddsFlipThreshold=0.30, MinSnapshotCount=3, DetectionIntervalSeconds=60) - DetectAnomaliesUseCase: iterates all events, loads last-24h live snapshots, runs detector, persists new anomalies with 1-minute dedup window - AnomalyDetectionPoller: BackgroundService polling every DetectionIntervalSeconds, gated by WorkerOptions.AnomalyDetectionEnabled (default true) - DI wiring: DetectAnomaliesUseCase registered Scoped in ApplicationModule; AnomalyOptions bound + AnomalyDetectionPoller hosted in InfrastructureModule - WorkerOptions.AnomalyDetectionEnabled added; appsettings.json updated - 13 domain tests + 4 application tests; total 245/245 passing (no regression)
maraphon-app
Sports betting odds analyzer for marathonbet.by.
Scrapes pre-match (/su) and live (/su/live) sports events, tracks coefficient changes
over time, and detects anomalies — in particular the "odds-flip" pattern where the
bookmaker freezes betting and then inverts underdog/favorite odds.
Tech stack
- .NET 8 + C# 12
- Blazor Hybrid — WPF shell hosting
BlazorWebView(designed to migrate to ASP.NET Core Blazor Server with no UI rewrite) - EF Core + SQLite (WAL mode) for local storage
- ClosedXML for Excel export
- AngleSharp for HTML scraping (with Playwright fallback for JS-rendered pages)
- Polly v8 for retry / circuit breaker / rate limiting
- MudBlazor UI components, Plotly.Blazor for charts
- Serilog structured logging
- xUnit / FluentAssertions / NSubstitute for tests
