What I'm looking for

I seek roles building scalable, governed cloud data platforms (lakehouse/warehouse) with strong DevOps, CI/CD, and cross-functional collaboration to enable analytics and compliance.

I am a Senior Data Engineer with 8+ years designing, modernizing, and operating enterprise-scale cloud-native data platforms across insurance, healthcare, and financial services. I build scalable Lakehouse architectures and high-performance Spark/PySpark pipelines, implement CDC-driven streaming, and deliver analytics-ready datasets for actuarial, clinical, and regulatory use cases.

I lead cloud migrations and infrastructure-as-code initiatives using Terraform, implement CI/CD and monitoring to reduce incidents and costs, and collaborate cross-functionally with analytics, actuarial, and compliance teams to deliver secure, governed, and high-performing data solutions.
