saas
End-to-end multi-tenant SaaS
Platforms where every customer is isolated by design: roles in the access token, per-tenant security rules and plans driven from billing. From the data model to the deploy.
What I build
Six fronts, one person accountable end to end.
whatsapp + ai
WhatsApp automation
Scheduling, reminders inside Meta's free window, and assistants that trigger real actions. The model proposes; the backend decides and writes.
payments
Payments and subscriptions
Checkout, verified webhooks, metered billing, add-ons and a customer portal. In pesos, with CFDI invoicing when the business needs it.
offline
Systems that work without signal
Installable apps that record on the device and sync when the connection returns. For warehouses, fields and points of sale, where internet isn't an assumption.
mobile
iOS and Android apps
Published to both stores from a single codebase, without maintaining two teams or two products that drift apart.
quality
Tests that block the deploy
Unit, security-rule and end-to-end tests running before every release. No green, no production — and that protects you, not me.
Has your operation outgrown a spreadsheet?
The first call is a diagnosis, not a quote in disguise. If your problem needs no software, I’ll say so.
