Hi, I’m Maira B. Carvalho.
I’m a PhD data scientist with 10+ years of experience spanning academic research and industry. My work sits at the intersection of machine learning and applied research, with a particular focus on problems where rigorous analysis drives real-world change.
Currently working as a Senior Data Scientist at Hrvatski Telekom, where my focus has been on predictive modelling for customer lifecycle management, large-scale geospatial and network analysis for pattern recognition, and data pipeline development and transformation. I’m also actively involved in modernising our data infrastructure and engineering workflows.
As part of a broader push toward AI integration, I recently completed an AI Engineering bootcamp, adding applied AI development to my existing foundation in machine learning, statistical modelling, and data engineering.
My background also includes a postdoctoral research position in machine learning and computational linguistics at the Cognitive Science and Artificial Intelligence department, at Tilburg University (Netherlands), which continues to inform how I approach data problems — with rigour, curiosity, and an eye for what the analysis actually means.
I work primarily in Python and PySpark, with experience across survival analysis, regression, clustering, time series, and process mining.
In this website you will find information about my research and publications, some of my work as a freelancer and my CV (both in English and in Portuguese).
Please feel free to get in touch with me.
