Resume

Data Science Tech Lead with 5+ years of experience building machine learning systems at scale in the telecom industry. I focus on end-to-end delivery: from designing algorithms grounded in maths to deploying production models in Spark on cloud infrastructure.

My background in applied mathematics drives how I approach problems — I look for the simplest model that solves the real business question, and I build pipelines that other people can maintain and extend.
