About Alvaro

Backend Developer | Java (Spring Boot) · REST APIs · PostgreSQL · Docker


Product-minded Backend Developer focused on Java and data. I build and extend REST APIs with Java + Spring Boot, design SQL data models, and work mainly with PostgreSQL/MySQL. Comfortable with Git and Docker-based workflows, I care about clean, maintainable code and clear delivery.

Real company experience (FCT Internship – Galvintec, Vigo): worked in an Odoo 17 CE (ERP/POS) environment, developing business logic with Python (ORM) and PostgreSQL, plus JavaScript and XML views for operational UI/flows. Used Docker (Doodba stack) and Git, delivered iteratively, and supported real POS operations (multi-store flows, location-based stock).

Projects:

RadioAcademy: Java/Spring Boot backend, REST APIs, Maven, JUnit, SQL database

OXI: Python backend (FastAPI) with Firebase

Reservas Flet: Python desktop app with Flet (MVC)

Services (freelance):

Build/extend Spring Boot REST APIs

SQL modeling & queries (PostgreSQL/MySQL)

Bug fixing, refactoring and performance-oriented improvements

Basic Docker setup and dev environment support

API integration with Angular frontends

Typical deliverables: versioned code, a short setup guide (README), and—if useful—a Postman collection / example requests so the API is easy to test and maintain.

Working style: milestone-based scope, clear communication, and minimal but useful documentation.

Location: Vigo (Galicia), Spain. Remote-first; available for hybrid in Galicia and on-site in Vigo/Pontevedra when needed.
Languages: Spanish (native), Galician (native), English (B2 – technical).
