What I'm looking for

I’m looking to contribute to teams that turn data into financial and strategic impact—building predictive models, production-ready data pipelines, and monitored machine learning systems with clear business outcomes.

I’m an Electrical Engineer with solid experience in Data Science, designing, implementing, and monitoring predictive models that deliver real business value. At IST, I’m developing advanced machine learning solutions for teleoperation, using statistical methods, data pipelines, and AI to improve pseudo-haptic systems.

In previous industry experience, I built and maintained predictive models, relational databases, and data pipelines to enable reliable ingestion, transformation, and continuous refresh of datasets. I also drive decision-making through exploratory data analysis, interactive dashboards (Tableau, Power BI), and customer segmentation using clustering, with a strong focus on model monitoring and measurable outcomes.
