About

I lead data engineering teams that build reliable platforms, accelerate delivery, and create measurable business impact. Over 16+ years, I’ve worked across distributed systems, data engineering, analytics platforms, and engineering leadership. My background spans hands-on platform architecture and people leadership, with experience scaling data systems, leading cross-functional programs, mentoring engineers, and building stronger execution systems for teams. Most recently at Hinge Health, I am leading a data engineering team with ownership across roadmap planning, sprint execution, hiring, and people development. Before that, as a Staff Data Engineer, I led platform modernization and optimization initiatives including a Databricks Unity Catalog migration across 1.2 PB of data, 400+ pipelines, and 10K+ objects; a Kafka migration that reduced costs by 50%; and optimization work projected to save $1M+ annually. Earlier in my career, I led teams building self-service data platforms, MLOps capabilities, real-time systems, and large-scale analytics products on AWS. Across roles, I’ve consistently enjoyed helping engineers grow, improving delivery systems, and creating the technical and organizational foundations that let teams move faster.
