ABOUT ME
Data Scientist Freelancer/Mentor/Educator
Data Scientist Freelancer/Mentor/Educator

Hello, I am a senior data scientist with experience in data science, machine learning, deep learning, and optimization. My expertise includes designing and evaluating recommender systems for co-founder matchmaking, building PySpark pipelines, and creating product categorization models for millions of products. I am also skilled in teaching and leadership, having founded the data science department of an online e-learning startup, where I developed and taught a course on data science and machine learning. Additionally, I have consulted on various AI projects, including applying MLOps to a real estate valuation model and segmenting medical questions into topics using deep learning-based methods like BERT + k-means. I have a Master of Science in Electrical Engineering with a focus on optimization applied to non-intrusive load monitoring. I have also received certifications in Deep Learning from the University of San Francisco and have completed a summer research project at Carnegie Mellon University. Overall, I am passionate about data science and always looking to take on new challenges and learn from others.
