The City of Porto runs its youth-internship programme on software I built alone.
I'm Francisco Cascalheira, a second-year Computer Engineering student at FEUP. For opPORTOnities I sat in the requirements meetings, designed the 12-model schema, wrote all 294 commits, and deployed it. It is in production now.

One system carries the argument.
Real systems with real users. The flagship gets the depth it earned; the rest is stated briefly and honestly.

The short version of who I am when I step away from the editor.
“A CV is a claim. A system in production is proof.”
That conviction comes from the Austrian economists I read for fun: value isn't declared, it's demonstrated in exchange. It's why this site is built like a dossier rather than a portfolio — one system, in production, examined honestly — and why I care more about who depends on my software than what the course syllabus says.
I'm a second-year Computer Engineering student in Porto. I like owning a product end to end: sitting in the requirements meeting, designing the data model, and being the person who deploys it and answers for it when it breaks. Away from the editor: philosophy, ancient history, cybersecurity, and Porto's tech and startup meetups.
