About

Lambda Expression is where I write about .NET the way I actually use it — in production, under load, with the trade-offs left in.

I'm Abubakar Riaz, a Cloud Architect and Microsoft Certified Trainer with more than 15 years across telecom and software. My day job is Azure and platform engineering; my backend roots are C# and T-SQL, and this blog is where the two meet — microservices, SaaS architecture, the .NET runtime, async and performance, and the design patterns that hold up when the system gets real.

Expect concrete, opinionated posts: what broke, what fixed it, and the reasoning behind the call. Certifications (AZ-204 / AZ-400 / AZ-305), open-source work at github.com/mabubakarriaz, and real projects back the writing.

If you build on .NET and care about doing it well, follow along — and tell me where you'd have done it differently.
