// About me

Bridging biology
& technology

Biomedical Scientist and MSc student in Bioinformatics for Health Sciences at Universitat Pompeu Fabra, Barcelona. My background combines wet-lab research with computational approaches — from cancer research on the c-Src proto-oncogene to working with omics datasets using R and Python.

I enjoy exploring data to uncover patterns, question assumptions, and translate complex results into meaningful insights. I'm particularly drawn to the intersection between biology, data analysis, and real-world biomedical applications.

This portfolio is part of the Databases & Web Development (DBW) course, showcasing a Clustal-Omega web app and a clinical trials data model.

Magnifier Analysis Platform

Magnifier automates a four-stage bioinformatics workflow through a web interface. After uploading gene expression and VCF data, it runs Differential Expression Analysis, Variant Effect Prediction, and data integration asynchronously to produce a final contingency table, while allowing users to monitor progress and download results.
