How engagements work

Every engagement starts with a written proposal: scope, deliverables, timeline and a fixed price. Prices on this site are starting points; the proposal is what counts.

The payment schedule and method are set in the proposal. Clients in Mexico are invoiced in MXN with a CFDI; other clients are invoiced in USD.

If the scope changes, we agree on the change in writing before the work happens, including any change to price or timeline.

Once paid in full, you own the code, eval sets, documents and infrastructure built for you. I keep general know-how and reusable tools that aren’t specific to your business.

Both sides keep each other’s non-public information confidential. I don’t name you as a client or show your work without your written permission.

Model APIs, cloud hosting and Meta’s WhatsApp fees are paid by you, either directly or billed at cost.

My total liability under an engagement is limited to the fees paid for it. Neither side is liable for indirect or consequential losses.

These terms and any proposal are governed by the laws of Mexico, with the courts of Querétaro, unless the proposal says otherwise.
