About Me

I’m Mario. Been doing this for 20+ years, currently living in the AWS serverless world.

Most of my time goes into event-driven architectures, API design, and helping teams escape monolith hell. You know that moment when you finally decouple a service and everything just… works? That’s my jam.

I build stuff that scales, ships, and doesn’t wake you up at 3am. Usually.

What I Work On

The usual suspects:

• AWS serverless & event-driven stuff — Lambda, EventBridge, Step Functions. The whole shebang.
• Killing monoliths — Helping teams break up that one massive service everyone’s afraid to touch.
• API design — Building APIs that don’t make you want to flip a table. REST, GraphQL, whatever solves the problem.
• .NET backend work — Still love C#. Fight me.
• Observability — Because “works on my machine” doesn’t cut it in prod.

Open Source

I maintain PowerCSharp—a .NET ecosystem I built because I got sick of copy-pasting the same utility classes into every project. It’s the stuff you wish the BCL had out of the box.

If you’ve ever written your own retry logic for the 47th time, you’ll get why this exists.

Certifications

A Bit More About Me

When I’m not coding or running, you’ll find me enjoying my vinyl collection on a Pro-Ject Debut PRO S Balanced through a Cambridge Audio CXA81 Mk II amp and ELAC Uni-Fi 2.0 UF52 speakers. There’s something about the warmth of analog sound that just hits different.

What This Site Is

This is where I dump the real stuff. Not the sanitized LinkedIn version, not the “executive summary” version—the actual code and patterns I use.

Think of it as:

• Code you can actually use (production-tested, de-branded, steal-friendly)
• Architecture patterns from real projects (with the scars to prove it)
• PoCs and experiments (because sometimes you just need to prove it works)
• PowerCSharp docs (because README.md only gets you so far)

If you’re a Staff Engineer, Tech Lead, or architect who’s deep in the trenches—this is for you. We speak the same language here.
