About
I'm an entrepreneur and full stack developer with 10+ years of experience building software. Today I lead HootFix, a company specializing in AI business automation and custom software: we audit processes, launch AI pilots in 3 weeks and measure ROI in the client's own numbers, all under contract (scope, price and dates in writing). I'm also the founder of Mantia, a tool to get more customers without ads, and the lead developer of my360sites.com, where I build new features, provide support and optimize sales, UX/UI and security. I've delivered 20+ projects: POS and management systems for the Altas Vistas restaurant group, legal platforms for Fong Abogados, websites and automation for Fort International (Miami), apps like Recyclo and websites like Montaña y Roca. Stack: Flutter, Dart, Laravel, Node.js, Angular, Vue.js, Ionic, Go, AWS, Firebase and databases (MySQL, SQL Server, Oracle). Services: AI automation, custom software, data & analytics, fractional CTO, code audits and launch marketing.
