What I'm looking for

I seek hands-on AI/ML roles where I can lead scalable models and MLOps, collaborate cross-functionally, drive product impact, and contribute to growth-focused teams.

I am a Senior Data Scientist with over nine years of experience delivering measurable business impact across healthcare, cloud infrastructure, real estate, and SaaS. I build data-driven solutions that improve efficiency, reduce costs, and enhance customer experience.

At Cohere Health I led AI-powered intake and decisioning pipelines that accelerated prior authorization turnaround by 70% and achieved 30–40% administrative cost savings, while driving 90% auto-approvals and high provider satisfaction.

Previously, I engineered observability and telemetry transformations at Chronosphere—reducing stored data by up to 84%, improving time-to-detection by 30–40%, and scaling ingestion to handle hundreds of millions of datapoints per second with 99.99%+ uptime.

I combine deep technical expertise in machine learning, MLOps, cloud platforms, and data engineering with strong leadership, cross-functional collaboration, and a focus on translating insights into product and business outcomes.
