PoupaNaEnergia

Solo product

An independent electricity-tariff comparator for the Portuguese market. Users upload a power bill, a Gemini-powered pipeline extracts their consumption, and a regulatory engine fed by ERSE data synced daily ranks every plan by real annual cost.

Problem
Households in Portugal cannot tell which electricity plan actually costs less against their own bill.
Constraint
Live ERSE data, messy PDF bills, and a product that has to be trusted with money.
Decision
Gemini extracts the bill; a regulatory engine ranks every plan by annual cost; Lighthouse CI runs on every push with hard a11y, SEO and LCP budgets.
Outcome
Live at poupanaenergia.pt — bill in, ranked plans out.
