About

A full-stack engineer with a designer's eye

I am a full-stack engineer based in Weston, Florida, working as an independent contractor through 27 Colab LLC, a two-person studio. I trained in multimedia design and programming at a Broward County technical college, which is why I start from the user and the information architecture, then build in code.

Most recently I was a core front-end engineer on a national pet insurer's quote funnel, marketing site and React Native app. I have also been the sole developer of a senior-living wellness platform, built a Next.js and Strapi platform for a property-services company, and shipped an AI phone receptionist to production, with SMS, email and Instagram agents around it. Before that: 60+ small-business websites across South Florida.

I care about the unglamorous parts that decide whether a product holds up: accessibility, speed, search visibility, tests, hosting, security and what each model call costs.

I work in English and Spanish, remotely or on site in the Miami and Fort Lauderdale area.

The projects behind these sentences are on the Work page; the code is under Open source.

Resume

Same person, same facts, four emphases. Each one leads with the part of my experience that kind of work asks for; pick the closest.
