Chi sono
I build custom web tools for small businesses: CRMs, dashboards, landing pages and apps that replace spreadsheets. Real projects in use: a loan management CRM, finance apps sold on Etsy, and a landing page with interactive calculators for an HR firm. Fast, mobile-first, no monthly fees — you own the code. Clear communication in English and Spanish, delivery in stages so you can give feedback early.
