Presentation
Hey — I'm Pablo. I build AI & ML solutions tailored to business needs.
Every business problem is different, and so is the solution. I enjoy understanding the underlying challenge, identifying the right technology, and building AI systems that are practical, scalable, and impactful.
Work experience
A glimpse into my professional journey.
From quantum-information research to production machine learning in finance— a quick tour of the roles that shaped how I work.
Data Scientist
Sep 2025 — PresentCaixaBank Payments & Consumer
- Built an end-to-end time-series forecasting pipeline (Oracle, XGBoost, Darts, Optuna), fully orchestrated with Apache Airflow.
- Developed a propensity model for consumer-finance product targeting.
- Implemented two agentic systems for internal operations — one with Power Automate, one with LangGraph.
- Automated multiple recurring internal workflows with Apache Airflow.
Theoretical Researcher
Feb 2025 — Jul 2025Quside
- Theoretical research on randomness extraction in semi-device-independent QRNGs.
- Ran SDP simulations with NumPy and Optuna.
- Co-authored a peer-reviewed paper.
Theoretical Researcher
Feb 2025 — May 2025ICFO — The Institute of Photonic Sciences
- Researched graph-neural-network applications for quantum state tomography.
- Built graph representations of quantum states with NetworkX.
- Implemented GNNs with PyTorch Geometric to enhance quantum-state reconstruction methods.
Software Developer
Jul 2023 — Sep 2023DataBot Technologies
- Built an automated web-scraping pipeline (Selenium, Playwright, BeautifulSoup) powering the backend of a production web application.

About me
Science taught me how to think.
My background has allowed me to develop a workflow grounded in the scientific method: reason carefully, question everything, and stay with a problem long enough to truly understand it. Those habits don't leave you. I bring them to every project I work on.
Academic background
MSc in Quantum Science & Technology
Double BSc in Physics & Mathematics
What drives me
Relentless curiosity
I like understanding how things work, all the way down.
Ambition & work ethic
I set high standards and do what it takes to meet them.
Competitive spirit
Sport sharpened my drive. I bring that same edge — and the discipline it demands — to my work.
Leadership
I lead by creating clarity. A well-defined goal and a trusted team can go a long way.
My projects
Things I've built.
A few projects that show how I think — end to end, from a question to a result.
Fraud Detection System
An end-to-end fraud-detection system trained and evaluated on more than 13 million card transactions — from imbalanced-data handling to model evaluation.
Most Streamed Tracks
An exploratory data-analysis project on the most-streamed songs on Spotify in 2023.
Quantum Information Paper
Published research on deterministic randomness extraction for semi-device-independent QRNGs.
