About

Who I am

David portrait

I'm a Full Stack Engineer from Pereira, Colombia, focused on building systems where AI acts as the intelligence layer, not just a wrapper around a model.

My work spans event-driven backend architectures, microservices migrations, and integrating LLMs into production workflows. I'm especially drawn to problems at the intersection of distributed systems and machine intelligence. I also enjoy the frontend side, because building interfaces that feel polished and easy to use matters just as much to me as the system behind them.

I'm currently working toward becoming a professional software architect, with a focus on building world-class products by applying the newest and most effective approaches.
