About Me

From Medellín to the World of AI

Hello! I'm Juan Esteban, a junior developer from Medellín, Colombia, with a passion for crafting elegant software and intelligent systems. Currently pursuing a degree in Data Science Engineering at Universidad Pontificia Bolivariana, I thrive on the intersection of robust software architecture and cutting-edge artificial intelligence.

My journey is defined by an obsession with Clean Architecture, Domain-Driven Design, and SOLID principles. I believe that powerful AI solutions are built upon a foundation of well-structured, maintainable, and explainable code. Whether it's designing scalable backend services or integrating advanced machine learning models, my approach is always that of an architect.

Beyond code, I'm a multilingual communicator, fluent in Spanish, English, and with a good grasp of French. I'm eager to contribute to innovative projects, embracing remote international, local Medellín, or freelance opportunities where I can apply my unique blend of engineering and data science expertise.
