About me

I am a Full-Stack Engineer with more than 5 years of experience building cloud-native applications, APIs, and internal automation tools. Originally from Colombia and now based in Berlin, I have always been driven by curiosity and the desire to understand how things work. Over the years, I have worked across backend development, AWS infrastructure, data processing, and modern web technologies. Today, I am focused on expanding my expertise in AI engineering and LLM integrations, creating practical features that improve products and team productivity. I value clean architecture, learning fast, collaborating with others, and contributing to meaningful software.
