Hello World — Why I Started This Blog

After 20 years in tech, I finally decided to start writing. Not because I suddenly had free time — if anything, I have less of it now than ever — but because I realized I’ve accumulated a lot of hard-won knowledge that exists only in my head and scattered notes. It’s time to put some of it out into the world.

I’m Carlos Diego Ramírez, an SAP Technical Architect based in Colombia. My career has been anything but linear. I started as a sysadmin, moved into security, picked up development along the way, and eventually landed deep in the SAP ecosystem. Each phase taught me something different, and the combination of all of them shaped how I think about building systems today. I see infrastructure, security, and code not as separate concerns but as facets of the same problem.

This blog will be a mix of things. I’ll write about SAP — the real stuff, not the marketing brochures. Configuration analysis, custom development patterns, the weird corners of ABAP and Fiori that nobody documents well. I’ll also write about building apps. Over the past year, I’ve been creating a personal suite of tools I call the “Crown” apps — everything from a German learning app to a project tracker — and there’s a lot to share about going from idea to deployed software when you’re a one-person team.

Why now? Honestly, because I built this site and it felt wrong to leave it empty. But also because the best way to solidify what you know is to explain it to someone else. If something I write here saves one person a few hours of debugging or gives them a new way to think about a problem, that’s more than enough reason to keep going.
