About Me

I'm Samuel, a Software Engineer from Panama focused on building systems that make an impact. I graduated from Universidad Tecnológica de Panamá and currently working in Business Intelligence at Banco Delta, using Microsoft Fabric, Azure and SQL to deliver data and KPIs that drive decision-making.


I enjoy building APIs and web applications, designing systems and integrating services to create scalable and efficient solutions, working with technologies like Python, JavaScript and React. I like solving complex problems and turning them into structured, reliable solutions.


I'm a self-learner at heart, always exploring new technologies and improving my skills across backend, modern web development, and the recent game-changer, AI. Outside of work, I’m into setups, gaming and the gym. I also enjoy exploring nature — especially rivers, natural pools and hidden spots across Panama.


Let’s build something great.
