For SickKids (Toronto), we developed electronic questionnaires for an offline tablet household survey within a maternal and child health program. Available in English, Amharic, Swahili, Chichewa and Dholuo, they were used in Ethiopia, Kenya, Malawi and Tanzania.

FAQ
Questions we often hear.
Still have a question? Talk to us directly.
How much does a project cost?
It depends on scope. After a short conversation we send a written scope and estimate, free of charge and with no obligation.
How fast can you deliver?
Websites usually take a few weeks. Systems are delivered in stages, so you see working software early and often.
Do you work with clients outside Brazil?
Yes. We communicate in English and Portuguese, by chat and email, and our time zone overlaps with North America and Europe.
Is AI-written code safe for production?
Every change is reviewed by a second agent and approved by a senior engineer, with automated tests. AI makes us faster; people stay accountable.
Can you take over or modernize an existing system?
Yes. We have modernized systems that ran for more than a decade, migrating step by step without disrupting the business.
Who owns the code?
It depends on the project. Our own platforms (SaaS) are licensed, not sold. For custom development, code ownership is agreed in the proposal, before any work starts. Your data is always yours.
