Full-Stack Software Engineer · Product-Minded · Design-Lover · Builder of J-Studio
I'm Juan Esteban Deossa Pertuz (a.k.a. Juanes), a full-stack engineer from Medellín, Colombia 🇨🇴
I see code as a form of poetry — a way to craft experiences that connect people, solve real problems, and scale with elegance.
My journey in tech was shaped by two milestones:
- 🧠 Platzi Master — where I trained with world-class engineers to build modern, production-ready software.
- 🌍 WorldSkills — where I represented Colombia in Web Technologies, placing among the best in the world.
Today, I’m the creator of Coffi, a platform for digital nomads to find their flow.
And I lead J-Studio, my personal initiative to build, design, and experiment with ideas that move both users and products forward.

✨ Coffi
A real-time platform that helps digital nomads find the best spaces to work, study, and thrive.
I designed, developed, and deployed the full-stack architecture — from idea to scale — blending product strategy with user experience, cloud infrastructure, and community-driven features.
Let’s build something meaningful — together.
