For businesses
Custom Software & SaaS for Businesses in Mexico
Through VALC Tech, my independent practice, I design, build and operate complete systems end-to-end: WhatsApp appointment booking (AgendaBot Pro), gym management (Sociko), point of sale with CFDI 4.0 invoicing (Numa), and produce trip-costing and cash control (JBP). Real products, in production, with real businesses behind them.
What I build
WhatsApp appointment booking
Your patients or clients book, reschedule and cancel from WhatsApp — no extra app. An AI agent handles the conversation; your calendar stays in control.
See the project →Gym & membership management
Members, plans, payments due and a collections list that flags every lapsed member with their phone number next to them.
See the project →Point of sale with CFDI invoicing
Sales, inventory and Mexican CFDI 4.0 e-invoicing built into one product — offline-first, so a bad connection never stops the register.
See the project →Custom systems for your operation
Like the produce-sourcing platform running in production for Agrícola Industrial JBP: per-trip costing, real margin and cash control.

- Tell me about your operation — a short message is enough.
- You get a proposal with a closed scope and price.
- I deliver in phases you can use from the first weeks.
One engineer, end to end, production-grade: the same stack that runs AgendaBot Pro, Nauti Test Pro and a real baseball league on Balltics.
