FAQ

What time zone do you work in?

US Central Time. Mexico has not observed daylight saving time since 2022, so the offset to US time zones shifts by an hour twice a year; we schedule around it.

How do you work with AI coding agents?

We use them every day to move faster, with senior review, tests and production experience deciding what ships.

How do we start?

Send us the repo or a description on WhatsApp or email. We reply with what we see and a proposed scope before any commitment.

Can we start small?

Yes. A written audit or a single fix is a common first step; you decide what comes next with the findings in hand.
