Hi there, I'm Alejandro and I live in Lisbon, Portugal.

I like building and selling software.

Beyond code and business, my interests include math, classical music, painting, and writing.

• Github Star Email Extractor: get stargazer data (people who star a repo) from a repo URL.
• Nummo: accounting software powered by AI - now turned into a banking layer for Openclaw agents.
• Typestamp: web app + Chrome extension that allows you to produce proofs of writing effort.
• Kerwis: my brand of pet furniture.
• Choose Right: my newsletter about behavioral economics.
• Kori: board game inspired by go.
