Mukesh Murugan
Solutions Architect · Microsoft MVP
Trivandrum, IN
8°N
I started codewithmukesh to share what I learn while building .NET applications. The official docs cover the features really well, but a lot of the harder parts of shipping production software, like system design decisions, Docker and Terraform setups, and the trade-offs between approaches, I had to learn on the job.
So I write the kind of articles I wish I had when I was starting out, and all of it is free to read.
Who I write for
Wherever you are in your .NET career-
01
Junior developers
You have just started your first .NET job. I try to explain things clearly enough to get you unstuck, without skipping the details. The EF Core, Docker, and system design intros are a good place to start.
-
02
Mid-level developers
You have been writing production code for a few years. Here you will find the patterns that hold up under real load, actual performance numbers, and the trade-offs that usually don't make it into the official docs.
-
03
Seniors and architects
You are designing systems and making the bigger decisions. I write about the reasoning behind architecture choices, deeper benchmarks, and the distributed system patterns I use in my own work.
-
04
Career switchers
You are coming to .NET from Node, Go, Java, or Python. I cover how the ecosystem fits together and how modern .NET is written today, so you don't have to dig through years of outdated Stack Overflow answers.
Topic requests
What are you stuck on?
I take topic requests from readers and reply to every email. If there is a .NET problem you can't find a good explanation for, feel free to send it over. It might become the next article.
