Machine Learning & AI Engineer with deep expertise in Python and a strong foundation in statistics and ML algorithms. I design, build, deploy, and monitor complex ML/AI systems at scale, and lead the teams behind them.

My interests span computer vision, self-supervised representation learning, language models, MLOps, and ML system design. I've worn many hats across a consultancy boutique, an AI startup, a software house, and a large enterprise.
