Hey, I'm Xavier.
I build things with AWS and AI — then write about what worked, what broke, and what it actually cost. Useful tools, honest lessons, no hype.
Serverless architectures, AI agents, browser extensions, and CLI tools. Open source when it helps. Cost-conscious by default.
This site is the public trail — projects, evaluations, and lessons. If something here saves you time or money, that was the goal.
Real projects with real AWS cost breakdowns
Bilingual content in English and Spanish
Open source by default
What I Write About
Every post comes from something I actually built, broke, or spent money on.
AWS & Cloud
Serverless patterns, event-driven systems, and data lakes — with real architecture diagrams and actual dollar amounts. Not theory, just what I've deployed.
AI/ML in Practice
AI agents, model comparisons, cost optimization. I test what works, track what it costs, and share what I find — no hype.
Dev Tools & Fun Builds
Browser extensions, CLI tools, workflow hacks. If I wished a tool existed and it didn't, I probably built it — and open sourced it.
