01 / BEGINNINGS

I didn't become a software engineer to write code.I became one to build worlds.

I started young, driven by curiosity — not just about how things work, but why people use them.

I wasn't content building tools; I wanted to build experiences — the kind that make life easier, smoother, more meaningful.

What captured me was the idea that with a few keystrokes, you could shape something real — something useful, beautiful, alive.

02 / PROCESS

I built one layer at a time until I could build it all.

From early prototypes to production-ready systems, I've walked the full stack and back.

I've worn every hat: designer, architect, frontend craftsman, backend strategist. I've turned napkin sketches into full-blown platforms.

Eventually, I built Coffi — my proudest creation, where I led every step from concept to scale, crafting not just an app, but a vision for the future of digital work, a platform born from scratch and grown with purpose.

03 / COMPETITION

I learned how to build fast, under fire —and with grace.

Representing Colombia in WorldSkills, I became national champion, then climbed the international ranks. There, I honed not just skill — but clarity, pressure-resilience, and performance under extreme stakes.

Those intense months taught me how to perform under pressure, how to learn fast, and how to build with both precision and beauty.

04 / DESIGN

I don't separate design from code —I see them as conversation.

<design>
</design>

Design and code are not separate disciplines. They're voices in the same conversation.

I code like a designer, and design like an engineer. I believe in systems that feel good to use, because intuition should be engineered too.

function design() {
return 'aesthetic' + 'functional';
}

05 / LIFESTYLE

I move freely — and so does what I build.

I live and work lightly. Remote by default. Grounded by curiosity.

Nomadic by choice, I collect places, ideas, and inspirations and pour them into the things I build.

Because great software, like great living, should be adaptive, intentional, and free.

06 / FUTURE

Still learning. Still building. Always chasing better.

An engineer. A designer. A founder in spirit. Rooted in creativity, trained through pressure, and always in motion — toward whatever's next.

Coffi Project

A platform built from the ground up to help digital nomads and remote workers find spaces where they can truly thrive. From idea to deployment, every line of code, design choice, and business decision was made by me — not just to solve a problem, but to craft an experience that moves with the way we live and work today.

Be Where You Thrive

Where the Idea Became the Product

I built Coffi because I needed it. As a remote creator moving from place to place, I craved more than coffee and Wi-Fi — I wanted spaces where I could truly focus, connect, and create. Coffi became my response to that search — not just an app, but a reflection of how I believe modern work should feel: intentional, flexible, and human.

My Language of Building

Every tool here is part of how I think — chosen not by trend, but by intent. This is the stack I use to imagine, shape, and scale meaningful digital experiences.

Let's Build Something Great!

Whether you're building a startup, scaling a platform, or shaping a product with purpose — I'd love to hear about it. I work best with bold ideas, thoughtful design, and teams who care about the craft.

Currently open to New Opportunities

product-focused roles, remote-first teams, or founder-led missions that value design and scale.
