Hi, I'm Diego 👋

I'm a Computer Science & Business Administration student at the University of Zaragoza. I build software to solve real problems - from microservices architectures to mobile apps - and I'm comfortable across the stack.

Currently looking for opportunities where I can keep growing as a developer.

Backend & Infrastructure Node.js Express REST APIs WebSockets Redis Docker

Data & Databases SQL MongoDB scikit-learn TensorFlow pandas

Tools & Methods Git Scrum/Agile Microservices


🚀 Featured projects

Full-stack interface for a distributed EV charging simulation platform. Built as part of a collaborative microservices project - I designed and implemented the API Gateway (Node.js/Express) and the React SPA that ties the whole ecosystem together. React Node.js Redis WebSockets Docker JWT MongoDB

Personal finance mobile app built with React Native and Expo. Tracks income and expenses with category breakdowns, time filters and summary charts. Structured with clean architecture (domain, application, data layers). React Native Expo AsyncStorage React Navigation

Online store for home delivery products, built in a team of three. I handled the database layer, business logic and backend persistence. Node.js MySQL
