I started codewithmukesh because the .NET docs are exhaustive, but the hard parts of shipping production software, I had to learn the hard way. The system-design decisions. The Docker and Terraform plumbing. The trade-offs that aren't in any official tutorial.
I write what I wish I'd had when I started. Free. No fluff.

05 · Who I write for
Whatever shape your .NET career is in
-
01
First-job devs
Just landed your first .NET role. I aim for the kind of clarity that gets you unstuck without dumbing things down. Start with the EF Core, Docker, and system-design intros.
-
02
Mid-level devs
Shipping production code for a year or three. Want the patterns that hold up under load, the perf numbers, and the trade-offs that don't make it into Microsoft Learn.
-
03
Senior + architects
Designing systems. Looking for the architectural decisions behind the framework choices, the deeper benchmarks, and the distributed-system patterns I actually run.
-
04
Career switchers
Coming to .NET from Node, Go, Java, or Python. The ecosystem map, the modern-.NET reset, and what's idiomatic in 2026 — without digging through 10 years of stale Stack Overflow.
