Proof, not a project grid.

Tools that move failures toward the keyboard, full-stack systems built across the boundary, and the complete public archive behind them.

Flagship work

The analysers behind the promise.

Most of the open-source work sits just before the mess: analysers, source generators and CLIs that make bad code complain early, where it is still cheap to fix.

LINQ001 intercepted

Compile-time safety · EF Core

LinqContraband

A Roslyn analyser that reads your LINQ the way the database will. N+1 queries and client-side evaluation get caught in the editor, not after a slow page has annoyed everyone.

LINQ001

Materialising before filtering pulls the whole table into memory.

Before

                db.Orders
  .ToList()
  .Where(o => o.Total > 1_000)

Quick fix

                db.Orders
  .Where(o => o.Total > 1_000)
  .ToList()

The database filters; the editor catches the expensive shape before review.

DILIFETIME001 intercepted

Compile-time safety · DI

DI Lifetime Analyzers

Captive dependencies, leaked scopes, lifetime mismatches: the bugs that look fine in tests and then embarrass you under load. This catches them while you type, with zero runtime overhead.

DILIFETIME001

A singleton captures a scoped dependency and quietly extends its lifetime.

Before

                AddSingleton<ReportService>()
AddScoped<AppDbContext>()

Quick fix

                AddScoped<ReportService>()
AddScoped<AppDbContext>()

The container graph becomes a compile-time contract instead of a runtime surprise.

CANCEL001 intercepted

Compile-time safety · async

CancelCop

A focused analyser for CancellationToken propagation across handlers, EF Core, HTTP and Minimal APIs. Cooperative cancellation, enforced, with code fixes that wire the token for you.

CANCEL001

A cancellation token reaches the handler, then disappears at the database call.

Before

                Task Handle(CancellationToken ct)
  => db.SaveChangesAsync();

Quick fix

                Task Handle(CancellationToken ct)
  => db.SaveChangesAsync(ct);

The code fix wires cooperative cancellation through the whole call chain.

Compile-time safety · mapping

AutoMapper Analyser

AutoMapper’s convenience hides its sharpest edge: the mapping you forgot. This flags missing and misconfigured maps at build, before they become a runtime shrug.

CPMigrate

Move an entire .NET solution onto Central Package Management without doing diff archaeology by hand. It checks dependency health, migrates carefully, and rolls back when reality disagrees.

Compile-time safety · config

ConfigContraband

Broken appsettings should not be a deploy-time surprise. Analysers for the .NET Options pattern that catch misbound configuration before it ships.

Compile-time safety · HTTP

HttpClient Resilience Analysers

Outbound HTTP failures are expensive and intermittent. These analysers catch unsafe retries, lifetime mistakes, dropped cancellation and response-ownership bugs while the code is still in the editor.

Reference architecture

CQRS Prototype

A clean-architecture CQRS reference: MediatR, DDD, transactional outbox. The patterns that keep enterprise .NET honest and testable.

Desktop · React + Tauri

AOE Overlay

A Tauri + TypeScript desktop overlay for live Age of Empires IV match data: web-built, native-weight.

Duplicate Photo Handler

A Rust + Tauri + React desktop app that hashes thousands of photos a second to clean up duplicate libraries: systems-language core, web UI on top.

The range

Every layer, one pair of hands.

Ten years in fintech buys the whole map. The same person tuning the grid render also wrote the calculation engine underneath it — and the Kafka consumer feeding them both.

React/TS UI ASP.NET API Kafka events SQL · Redis

src/features/schemes/SchemeGrid.tsx TSX

const { data: schemes = [] } = useSchemesQuery(); return (  <AgGridReact rowData={schemes}    columnDefs={columns} animateRows />);

tsc --strict · 0 errors

The front Data-dense React + TypeScript — RTK Query, AG-Grid, Recharts. Frontends built from scratch for institutional users who read numbers for a living.

src/Engine/LiabilityEngine.cs C#

var curve = DiscountCurve.From(market, asOf); var presentValue = scheme.CashFlows.Sum(cf =>    cf.Amount * curve.DiscountFactor(cf.Date));

LinqContraband ✓ · 0 diagnostics

The middle C# calculation engines — liability metrics, discount curves and funding ratios. Right answers, every time, with an audit trail.

src/Messaging/OutboxRelay.cs C#

await outbox.Enqueue(tradeRebooked, tx, ct);await tx.CommitAsync(ct);// relayed to Kafka after commit

CancelCop ✓ · token propagated

The plumbing Event-driven .NET on Kafka — transactional outbox, idempotency keys, schema registry. The plumbing that is not allowed to lose money.
