I started with the screen. I stayed to ship it.
I’m Andre Castro, a Brazilian designer and full-stack developer based in New Jersey. I care about what people see on a screen and what has to happen behind it for that experience to work.
How I got here
That has taken me through hardware, web development, municipal systems, mobile interfaces for education, and government web projects in the United States.
I started in technology at 17. Working with hardware gave me a practical starting point: understand what is happening, find the problem, and make the system useful again.
At IM@ in Campinas, beginning in 2007, I worked with design, PHP, JavaScript, and SQL in a municipal setting. My path continued through EE2 Agency in 2013 and Mosyle in 2014, where my work included mobile interfaces for education.
Today, I’m a Web Designer & Full-Stack Developer at AlphaDog Solutions in New Jersey, working on government and municipal web solutions. Projects shown from that role are credited to AlphaDog.
Why Built By Andre exists
Built By Andre is the home for my independent client work and products. It gives that work a clear identity and a consistent way of being delivered.
I work directly with clients who need both design and implementation. We define a useful piece of work, make the decisions it needs, and carry it through to delivery.
AI agents help me draft, scaffold, and handle repetitive build tasks. They give me another way to move the work forward. I still own the decisions, the review, and the quality of the result.
My job is to understand the screen. And to deliver it simple.
