Personal Projects
Galivivienda VPO Calculator
Civic TechInteractive calculator to analyze the real cost of a cooperative VPO housing unit in Vélez-Málaga, based on the public documentation for the Galivivienda Fortalezas de Vélez development (188 units, EMVIPSA). Built because the official information is fragmented across multiple contracts with unclear terms — lets users simulate different IPC scenarios, rental years, and discount percentages to calculate the actual total cost before signing. Implementation: real-time financial calculations with monthly compound interest, a rent evolution chart rendered with pure JS (no canvas or libraries), responsive design with adaptive grid and native mobile bottom-sheet, and full SEO with JSON-LD. Immediate organic traction when shared in local Facebook groups.
