.NET systems that hold up in production: queues, integrations and APIs nobody has to restart at three in the morning.
A visual flow editor. Drag blocks onto a canvas, connect them, configure each node in a side panel, then run the flow against a live .NET backend.
Run the slow query and the optimised one side by side, against a real database, and read both plans.

live p95 -uptime -
A distributed .NET system with two faces, the product a customer uses and the machinery underneath reacting in real time.
A language model is given a slow query and asked to make it faster. Then the database decides whether it did.
5 questions · the database decides
Both models miss the same question, and both miss it confidently — the textbook rewrite is slower than the query it replaces.
live p95 -uptime -
A .NET Framework 4.8 to .NET 8 migration, documented decision by decision, including the parts that are still on 4.8.
A reverse proxy went in first, routing 100% of traffic to the application it was there to replace.
MSMQ has no .NET 8 successor, so it kept a 200-line 4.8 process instead of a rewrite nobody could scope.
Twenty RDLC reports were frozen where they are. The stage produced no code, and that was the outcome.
The two hosted services under six load shapes, run the way a real engagement is run. Objectives first, the process measured next to the client, a findings log with re-tests, and the numbers committed to the repository.

Eighty editors plus a stream of spectators against Flow Studio. Half the run requests were refused because all six slots were busy, none failed, and the latency tail stayed where it was at two users.
