About Xhensilda

I am a Data Science and AI Engineer with a PhD (Cum Laude) from UPC Barcelona and currently working as a Research Engineer at the Barcelona Supercomputing Center. My expertise spans machine learning, neural networks, IoT data systems, and AI agent development.
I help organisations extract real value from their data — building models that work in production, not just in research. My published work covers anomaly detection, sensor calibration, outlier detection frameworks, and time series analysis, applied to real industrial and environmental systems.
I take on freelance projects in machine learning, data science consulting, AI agent development, and technical advisory. I work with a small number of clients at a time to ensure quality and genuine commitment to each project.

  • Universitat Politecnica de Catalunya
    PhD (Cum Laude)
    RESEARCH
    October 2021 - January 2026 (4 years and 3 months)
    Barcelona, Spain
    I hold a PhD (Cum Laude) in Data Science from the Universitat Politècnica de Catalunya. My doctoral research focused on applying machine learning and deep learning models to improve the quality of data collected by low-cost IoT sensors used in air quality monitoring systems.This work involved developing and implementing state-of-the-art models — including LSTM, BiLSTM, Transformers, and Gaussian Processes — for sensor calibration, anomaly detection, and outlier detection in real-world environmental sensor networks. The research was published in several IEEE journals and contributed to EU-funded projects in IoT and environmental monitoring.

  • Metropolitan University of Tirana, Univeristy of Tirana
    Assistant lecturer
    RESEARCH
    September 2019 - September 2021 (2 years)
    Tirana, Albania
    Assistant Professor at two universities in Albania, teaching technical and mathematical subjects to engineering students. Courses delivered include Numerical Methods for Engineers (Matlab/Octave), Probability and Statistics, and Graph Theory.
    This role strengthened my ability to communicate complex technical concepts clearly and accessibly — a skill I bring directly to my work with clients and research teams. Teaching these subjects at university level required deep mastery of the underlying mathematics and the ability to make it practical and applicable for students.
