Hi, I'm Jeslin Lois

A passionate Generative AI Engineer and Data Scientist with over 6+ years of experience in building AI/ML solutions across global client projects. Also a creator passionate about making tech simple and accessible. My mission is to teach Python for Data Science from scratch — breaking down complex concepts into easy, practical lessons anyone can follow. Through my projects, tutorials, and insights, I aim to inspire learners to build their own path in AI and data, one line of code at a time.
