About
Who I am
I'm a Full Stack Engineer from Pereira, Colombia, with a focus on building systems where AI is the intelligence layer, not just a wrapper around a model.
My work spans event-driven backend architectures and microservices migrations to integrating LLMs into production workflows. I'm drawn to problems at the intersection of distributed systems and machine intelligence. The frontend side comes naturally too, building interfaces that feel polished and easy to use is just as important to me as the system underneath.
Currently studying Systems and Computer Engineering at Universidad Tecnologica de Pereira, working toward becoming a professional software architect focused on building world-class products by adopting the newest and best approaches.
