What I'm looking for

I am looking for a role where I can build scalable backend systems and contribute to infrastructure decisions in a collaborative engineering environment. I value technical excellence, ownership, and continuous learning. I want to work with teams that prioritize clean architecture, reliability, and long-term product sustainability while encouraging growth and innovation.

I am a software engineer with strong experience in backend development and infrastructure-focused systems. Over the past years, I have worked on scalable web applications, APIs, and white-label platforms, focusing on clean architecture, performance, and maintainability.

My background includes working with Node.js, .NET, TypeScript, and React, as well as experience with CI/CD pipelines, containerized environments, and distributed systems concepts.

I am passionate about building reliable systems, improving engineering standards, and continuously learning new technologies. Outside of work, I enjoy studying system design, observability, and learning new languages like Spanish.
