The Builder Behind the Systems ✨

Engineer, entrepreneur, and lifelong builder.

I'm Julissa, an AI engineer with a decade of experience building data-first systems across ed-tech, health-tech, web3, and finance. Today, I channel all of that into building my own businesses, tools, and systems that create real freedom.

Born in Peru 🇵🇪, raised on ambition, and now building from sunny Florida 🌴. I believe the best technology should feel personal, intentional, and kind.

I help founders and technical leaders architect intelligent systems, validate data pipelines, and build profitable businesses powered by automation. I ship production code, build my own tools, and support clients from architecture through deployment.

I also run Breezy Keys with my partner, a short-term rental business that I genuinely love every part of. Interior design and feature planning, data analysis on rental markets, remote tech setup, guest comms. It's where engineering meets hospitality, and it's one of my favorite things to consult on.

Some of my recent projects include Ocala Pet Retreat, Hispanic Notary Services, and ProofFix. More portfolio pieces coming soon!

How I Build

  • 💖

    People First

    The best systems start with empathy. I talk to real users, understand real pain points, and build solutions that actually help.

  • 🔍

    Data Integrity

    Every system is only as reliable as its data. I validate every assumption so decisions are grounded in truth, not guesswork.

  • 🌱

    Build to Grow

    I design modular, composable systems that start simple and scale gracefully. No over-engineering, no premature optimization.

Let's Build Something Together ✨

Whether you need an AI system, a beautiful website, cloud help, or rental business strategy, I'd love to chat.
