What is this?
A personal space to share what I learn, implement, and find interesting in the world of technology. Real-world guides, cybersec for everyone, and curiosities.
I’m Cesar Rosa Polanco, a professional in infrastructure, cloud, and security. I’ve seen attacks, built systems from scratch, broken things (intentionally and otherwise) in production. Everything here is field-tested: I’ve used it, seen it work, or watched it fail. No pure theory, no buzzwords.
The stack
Astro as the framework, Cloudflare Pages Pro for hosting, GitHub for deployment. Push to main and live in seconds. Fully bilingual site (Spanish/English), no CMS, no fuss.
What will you find here?
Articles on AI, cybersecurity, cloud, infrastructure - all from the trenches, not from theory. Tools I use, common mistakes I see, and how I fixed things that broke. No ads, no affiliate links, no commercial agenda.
Start here: If you want to navigate the topics we cover, head to Start Here for a quick guide. If you’d rather jump straight into practical content, read Popeye’s Spinach - it’s my recommendation for a first article.
Welcome to the space.
