Curriculum Vitae
Andrés F. Quintana — Software Engineer
Software engineer by trade, problem-solver by nature. Hands-on with .NET Core, React, Node.js, and cloud tooling, I enjoy building scalable things that quietly make people's days easier. I thrive in fast-paced, team-oriented environments where clear communication and curiosity are valued as much as clean code.
