I build automation on real business data: systems that read, check and act, and that a person can always verify.
About
I study Business Management at ISCAL in Lisbon, finishing in 2027, and I run operations and systems at my family's minimarket. There I built a system that reads supplier invoices, proves them against the Portuguese fiscal QR code and proposes new prices for a person to approve.
What I care about is the part that makes automation safe: tests, audit trails, backups and a way to undo every change.

Projects
Reads supplier invoices, checks every line against the fiscal QR code VAT rate by VAT rate, and proposes new costs and shelf prices that a person approves. Photograph a real Portuguese invoice with your phone and watch it being read and proved, in the store app's own design. Nothing leaves your device.
A trading strategy builder: backtests with fees and slippage, tests that catch overfitting, live Bitcoin candles, and an AI analyst that reads the chart and calls the engine instead of guessing.
A Power BI model that answers one question: where is the store losing margin because prices fell behind costs? Products sold below cost are ranked by money lost.
Each new invoice is summarised, logged to a spreadsheet and routed by email: "ready to approve" or "needs a person", with the reasons. It never writes a price.
I connected Kronos, an open model trained only on price candles, to StratForge and tested it on a year of Bitcoin data it had never seen. It showed no reliable edge. The write-up explains how I measured it.

I am looking for a hybrid role in Lisbon, or a remote one, in business and finance systems, automation or AI.
