Long-form tutorials and engineering notes on .NET, React, AI/ML, and SaaS architecture.
Large data grids in React: server pagination, infinite scroll, virtual scrolling, AG Grid, TanStack Table on the same 250k-row dataset — real code + metrics.
30 senior React interview questions with deep answers across Hooks, Reconciliation, Fiber Architecture, and Performance — the mental model interviewers test.
1.2M PDF reports in 48h on ASP.NET Core + CQRS + PuppeteerSharp + Azure — browser pooling, autoscale workers, CDN cache. Mattrx p95 9s, $0.0004/PDF.
Part 4 (finale) of a 14-year ASP.NET series: choosing Azure architecture, real observability, and AI as an engineered component.
Part 3 of a 14-year ASP.NET series: the performance techniques that move p95, when microservices help, and the patterns that earn their keep.
Part 2 of a 14-year ASP.NET series: LINQ, EF Core, and SQL Server done right — where the boundary runs, the EF habits, and reading the plan.
Part 1 of a 14-year ASP.NET series: why clean code isn't enough, the OOP that matters, and how SOLID changed the systems I build.
Mattrx runs Azure Service Bus, Event Grid, and Kafka side by side. The decision framework, real code, and exactly when to pick each.
Prompt injection, data leakage, tenant breaches — seven real attacks on enterprise LLM apps, and the Mattrx production code that stops each one.
Our dashboards aggregated a 1.2-billion-row table at 2,100ms. Here's the partitioning, columnstore, and read-model design that got us to 48ms, with code.
The finale — a year of running MCP in production at Mattrx: what held, what broke, what we'd do differently, and the whole series in one mental model.
The MCP servers you built aren't tied to one model. Here's wiring MCP into OpenAI (client-side + the hosted tool) and agent frameworks — one server, any model.
