Hey There đź‘‹

Mario Arce

I’m Mario, and I’ve been building stuff on the cloud for 20+ years. This is where I share the real code, the actual patterns, and the things that worked (and didn’t) in production.

You know how LinkedIn is all polished takes and Medium is long-form pontification? This is different. Think of it as the engineering channel on Slack—technical, unfiltered, peer-to-peer.


What’s Here

🏗️ Architectural Patterns

Real system designs from actual projects. Not textbook stuff—the messy reality of microservices, event-driven systems, and what happens when theory meets production at 3am.

đź’» Production Code

The kind of code you actually ship. Custom implementations, solutions to gnarly problems, and the helper classes that save your sanity. De-branded and ready to steal.

🔬 PoCs & Experiments

When you need to prove something works before betting the sprint on it. Interactive demos, quick prototypes, and “let me show you what I mean” examples.

đź“š PowerCSharp

My .NET open-source ecosystem. Built it because I got tired of writing the same boilerplate in every project. You probably have too.

Where Else to Find Me

I’m scattered across the usual spots:

LinkedIn — The polished version. Career stuff, architectural hot takes, leadership thoughts. You know, the content your CTO follows.

Medium — When I need more than 280 characters. System design deep-dives, modernization war stories, lessons from 20+ years of “oh crap” moments.

Hashnode — Step-by-step technical guides. The kind you bookmark at 2am when production is on fire and you need answers.

DEV Community — Quick hits, community vibes, the occasional “TIL” post. More casual than Medium, less formal than LinkedIn.

GitHub — Where the actual code lives. PowerCSharp and other OSS projects I maintain. PRs welcome, issues even more so.
