About Me

I'm a Full Stack Software Engineer based in Lima, Peru, with experience developing enterprise web and mobile applications.

My main focus is backend development with C# and .NET, combined with frontend technologies such as React, React Native, Angular, and TypeScript.

I've contributed to HR technology and financial applications, working with REST APIs, cloud services, databases, and enterprise integrations.

I enjoy solving technical challenges, learning new technologies, and collaborating with engineering teams to build reliable software.

Outside of software development, I'm passionate about astronomy and enjoy swimming and calisthenics. These interests keep me curious, active, and motivated to continuously learn and challenge myself.
