Hi! My name is Eduardo Fuentes, a Software Engineer with over 5 years of experience designing and developing backend applications for mission-critical systems, working on platform modernization, migration, and integration projects in high-availability environments.
My main focus is backend development with Java (Spring Boot) and Node.js (Express and NestJS), applying principles such as SOLID, Clean Architecture, domain-driven design, and solid testing practices to build maintainable and scalable software. Although my specialty is backend, I also have experience building interfaces with React, which lets me collaborate across the full stack and communicate effectively with frontend teams.
The most relevant milestones of my career — the decoupled-architecture migration of critical ChileCompra services, Fast Checkout for Ripley, and the query optimization that cut response times — are detailed role-by-role in the Experience section.
In my free time I explore new tools and frameworks, and I also create content about technology. My goal is to keep growing into roles where I can contribute not only by writing code but also by designing scalable systems, making architecture decisions, and building products with real impact. If you're interested in collaborating or just want to talk about technology, feel free to reach out.
