About the author
Isaiah Clifford Opoku
Software Engineer · Microsoft MVP
I've spent over five years building scalable applications and cloud solutions with .NET, AWS, and Google Cloud. CliffTech is where I write up what I learn along the way.
My goal is simple: make complex technical concepts easy to follow, so you can build better applications with modern tools and best practices. Outside of writing, I make videos on YouTube and speak at tech conferences and meetups.
What I write about
Production-first .NET
ASP.NET Core, EF Core, and C# patterns I've used in real systems, with the trade-offs explained, not just the happy path.
Cloud architecture
Building and running .NET applications on AWS and Google Cloud, and the design decisions that hold up at scale.
Complex topics, made clear
Step-by-step deep-dives that take a hard concept and make it something you can apply in your own code the same day.
Who I write for
Wherever you are in your .NET journeyFirst-job developers
Just landed your first .NET role. Start with the fundamentals explained clearly, without dumbing them down.
Mid-level engineers
Shipping production code already. Looking for the patterns, trade-offs, and cloud decisions that hold up at scale.
Architects & leads
Designing systems and making the calls behind the framework choices — AWS vs. Google Cloud, architecture, and beyond.
Career switchers
Coming to .NET from another stack. A map of what's idiomatic today, without digging through years of stale answers.
Got a .NET or cloud problem you're stuck on?
I take topic requests and read every message. If there's something you can't find good writing on, send it over it might be the next deep-dive.
