Head of Data science at Paypal
Hi, I’m Santhosh. I have over a decade of experience in data science, machine learning, and experimentation, and I currently lead Data Science for the PayPal Consumer App, driving growth for 200M+ global users. My work spans end-to-end data pipelines, advanced causal inference, and large-scale ML modeling, with a strong focus on turning complex data into clear, compelling stories that influence strategy.
I’m equally passionate about mentoring—helping early-career data scientists sharpen their technical skills, build confidence in stakeholder communication, and grow into impactful leaders. I enjoy bridging the gap between the technical and business worlds, ensuring insights don’t just sit in notebooks but shape real-world outcomes.
I can help you with: • Data science & ML career strategy • Python, modeling best practices & experimentation design • Data storytelling & communication with stakeholders • Portfolio and resume reviews
