Portfolio / 2026I’m Javi, a Computer Science student connecting theory with practice through software engineering, machine learning, and financial technology.
01 / Selected projects
Practical engineering, considered decisions,
and
experiments with something to say.

A private-markets management platform that brings customers, investment positions, and reporting into one workflow. Developed around a practical financial use case in collaboration with a stakeholder.
Average confidence Accuracy
600 held-out questions. Fine-tuning improved accuracy; temperature scaling improved calibration while accuracy stayed at 65.17%.
02 / Independent ML experimentation · DIY JEV
Evaluating Qwen3-0.6B on CommonsenseQA: LoRA fine-tuning improved accuracy, then temperature scaling brought confidence closer to observed performance without changing the predicted answers.

A private iOS and Android application focused on secure account connections, shared-data synchronisation, and a reliable mobile experience.
Inside the engineering02 / About & education
I like understanding how software works beneath the surface—and using that understanding to build things that are useful.
I’m studying BEng Computer Science at the University of Edinburgh. My interests span full-stack development, machine learning, algorithms, computer systems, and the architecture behind databases. Financial technology is a particularly interesting place for me to connect software with analytical thinking.
Alongside my degree, I build independent projects and experiment with ideas beyond the syllabus. My technical work also includes C and MIPS assembly, stack-based parsing and syntax checking, object-oriented programming, and data analysis with Python and pandas.
Away from the keyboard: skiing, travelling, fitness, and cooking. I speak English, Spanish, and French.
Technologies I’ve worked with across projects, experiments, and my degree.
03 / Experience & leadership
Research, collaboration, and making
technical ideas
accessible.
Student society · Investment research & team leadership
Researching companies, evaluating business and financial performance, and contributing to investment pitches. I have led teams of five analysts in junior and senior analyst contexts. My research has included Naturgy’s business performance, financial position, capital expenditure, and investment considerations.
Madrid · Summer 2026 · Approximately two weeks
Worked with approximately 45 children and helped lead educational activities in science, engineering, and computer science. An opportunity to adapt technical ideas for younger audiences and develop communication and leadership skills.
Previous · Independent development
Built web applications and scripts for FiveM servers through Pixel Labs, an independent game-modding store. An earlier part of my experience developing software beyond the classroom.
