A cold launch forks nothing. Every pane is a plain terminal until you say otherwise.
Cotidia comes from cotidiano, the Spanish word for everyday. It is the whole brief.
Systems
Websites, mobile apps and multi-tenant platforms for businesses that cannot afford surprises.

A row closes on evidence from the running app, never from a demo. We publish the open ones too.

From a first website to a multi-tenant platform, we design, build and operate the systems a business runs on.

Fast, accurate, easy to change. Content, commerce, and analytics that tell the truth.
iOS and Android from one codebase, or native when it matters. Store-ready, with the backend to match.
B2B and B2C platforms with real tenancy, roles, billing and audit trails. Built to scale without a rebuild.
Payments, ledgers, CRMs, ERPs and the glue between them. Idempotent, observable, recoverable.
Assistants and automation where they pay for themselves, with guardrails and evidence rather than demos.
Measurement repair, production safety, staged rollouts, monitoring. The boring parts, done properly.
How we work
We sit with the work first: where it breaks, what it costs, who it wakes up at night. One bounded problem, stated in your words.
Each behaviour is a pass/fail row with named evidence. A row closes when it works in the real thing, observed in pixels or logs, never in a demo.
Staged rollouts, monitoring that means something, and a recovery path for the day something goes wrong.
Two lines of work, one standard. Products we make and systems we build for you, held to the same rule: it has to hold on an ordinary day.
