Software Engineer

Hi, I'm Beatriz Ristau

I build robust backend systems with Java & Spring Boot, crafting scalable digital experiences through clean code and innovative solutions.

My background and journey

About Me

I am a passionate Software Engineer with a solid foundation in designing, developing, and deploying robust backend applications. I specialize in Java, Spring Boot, and object-oriented design, with hands-on experience building scalable backend services and developing RESTful APIs.

My background also includes working with relational databases like PostgreSQL and Spanner DB, and deploying solutions in cloud environments such as Google Cloud Platform (GCP). I’m driven by clean code, automation, and performance.

I am eager to contribute to innovative projects and am continuously looking to learn new technologies and concepts to improve as a developer - currently learning React to expand my full-stack capabilities, and exploring AI agents to deepen my understanding of intelligent, autonomous systems.
