Background

I'm originally from Medellín, Colombia, and have called Barcelona, Spain home for the past two years. With a background in Audiovisual Communication and nearly a decade of experience in sales, I bring a unique perspective to development that combines technical skills with strong business acumen.

Before transitioning into web development, I ran my own e commerce business. This experience gave me firsthand insight into business operations and the critical role that digital solutions play in driving growth and success in today's market.

As a full stack developer, I've had the opportunity to work with various companies, technologies, and frameworks. These experiences have allowed me to develop a versatile skill set and the ability to create tailored solutions that address specific business challenges and user needs.

AI & Automation Focus

Over the past year, I've specialized in building AI agents and multi agent systems. I'm fascinated by how autonomous agents can reason, plan, and act to automate complete business processes—not just individual tasks.

I work with modern AI frameworks like LangGraph, CrewAI, and Firebase Genkit, combined with LLMs from OpenAI, Anthropic, and DeepSeek. My focus is on production ready systems that integrate with existing tools and deliver measurable ROI.
