What I'm looking for

I want to keep building end-to-end products—data model, API, real-time layer, UI, deployment—especially multi-tenant SaaS with strong security like RBAC and audit logs.

I build multi-tenant web and mobile products end to end, including KB Business HUB for Constructora Grupo KB. I designed the hybrid multi-tenant data layer with per-organization MongoDB isolation plus shared global data, then shipped real-time Socket.IO sync, key-based RBAC, scheduled payroll cron jobs, and the Android time-clock kiosk.

Before that, at Tomateros de Culiacán I built full-stack web and mobile applications for internal operations, catalogs, inventory, and fan engagement, and also handled database administration work like T-SQL reporting and backup/disaster recovery routines. I keep delivering and maintaining production systems under contract while continuing a full-time build cycle.
