Founder & Developer Milo
Founded and built Milo, an NFC loyalty and appointment-booking SaaS for local businesses. Developed Milo Fanatic, an NFC digital loyalty card product, and Milo Agenda, an online booking product with WhatsApp reminders. The platform is in production with a barbershop, a clinical laboratory, and a dental office.
Designed the PostgreSQL and Supabase data model with 29 tables and more than 60 PL/pgSQL functions that implement plan limits, usage rules, and core business logic. Implemented row-level security to isolate each business's data.
Built custom dashboards for non-technical owners to review customer satisfaction and defined product metrics including scans, completion rate, dashboard usage, and repurchase. Detected visit fraud in production data and implemented database rules using NFC chip counters, one visit per day, phone validation, and append-only movement history.
Maintains 48 versioned migrations and tests each migration in rolled-back transactions before production deployment.
