A senior full-stack developer in Puebla — built for US and Mexican clients
Nearshore work in your timezone, in fluent English, without US-agency pricing.
I'm Cesar Ayala, a senior full-stack developer based in Puebla, Mexico. I build web apps, mobile apps, and AI features in Go, Python, React, and React Native — for US and Canadian founders who want a nearshore partner who works their hours, and for Mexican companies that want a local senior dev they can actually meet. Same continent, same timezone, real English, and seven years of shipped products behind every line.

FAQ
- How does nearshore actually help my US or Canadian project?
- I'm in Puebla, which sits in US Central time most of the year, so we overlap a full workday. You get standups, quick calls, and same-day answers — not a 12-hour delay. I've already shipped fintech SaaS for US clients (FinHOA), so cross-border delivery isn't new for me.
- What does a project cost?
- Most engagements land between a few thousand dollars for a focused build and the cost of a part- or full-time senior dev for ongoing product work. You get senior, US-timezone work without US-agency rates. Tell me the scope and I'll give you a concrete number, not a range that hides surprises.
- How long until I see something working?
- For a defined first milestone — a working MVP, a key feature, an app store-ready build — usually two to six weeks depending on scope. I ship in visible increments so you're never waiting in the dark to see progress.
- Why work with you instead of a US agency or an offshore team?
- You get one senior person who writes the code, in your timezone, in fluent English, at Mexican rates. I've done the local Mexican work (Truxgo, Mercanto) and the cross-border US work (FinHOA), so I understand both markets — and I teach this stack to over a million people, so the fundamentals are solid.
