03 / BEHIND THE PIECESCuriosity as a starting point.
I like to understand.
And then, build.
I’m Daniel, a software developer and Computer Systems Engineering student at TecNM Culiacán. I build tools that solve concrete problems for the people who use them.
I worked in development and QA at ZazPay until March 2026, evaluated AI-generated code at Outlier and developed backend features at Faena Uniformes. I’m now building ARE Engine and Menu Engine, and looking for a junior role or technical collaboration.

How much does a project cost?
It depends on scope: number of pages or screens, integrations and data to migrate. After a short conversation I send a written scope with a fixed price per stage, so there are no surprises.
Do you work remotely?
Yes. I’m based in Culiacán, Mexico, and can meet in person there; everywhere else I work online, in Spanish or English (B2).
Are you an agency?
No. You talk directly to the person who designs, builds and tests your project. Code, credentials and documentation are yours.
Are the demos production products?
The 3D demos are interactive representations using sample data. Each case study explains the actual status: ARE Engine is validated in a controlled environment and Menu Engine is a functional beta MVP.
Are you open to jobs?
Yes, I’m open to software development, QA or automation roles. My résumé is available on this page.
CONVERSATIONS BUILD THINGS TOO.✳
What if webuild it together?
Tell me what you want to build, what needs improving and whether you have a date in mind. If you’re hiring, I’d also like to hear about the opportunity.
