About me
Hi, my name is Javier and I'm a Computer Engineer from Salamanca, Spain.
I love finding simple and effective solutions to complex problems, learning new technologies along the way.
This has lead me to specialize in custom tools development, integration and deployment, automating as many processes as possible.

Used TensorFlow in Python3. - Web application pentesting: Found and fixed several SQL injection and XSS vulnerabilities. - Front end development using HTML5, CSS3 and JavaScript. - Hosted an Ethical hacking event: Performed a pentest in a real-world sceneario (using the platform HackTheBox) live on Twitch.
Computer Engineering Masters Degree - University of Salamanca (10-2021 to 02-2023)
- Average degree grade: 8.84/10 (3.537/4 GPA). - Final degree project grade: 9/10. - Final degree project thesis: Analysis, design and implementation of a RESTful Service Oriented Architecture (SOA) for an online boardgame. The architecture is so that any boardgame can be implemented in a natural and easy way. The services have a clear OpenAPI 3.0 endpoint specification that allows seamless integration with several tools such as Postman and FastAPI. Everything is containerized via Docker Compose and deployed on a private server.
