I am a Lead Data Engineer specializing in cloud data platforms, MLOps, and scalable data infrastructure.
United StatesI am a Lead Data Engineer with 12+ years building scalable cloud lakehouse platforms and data infrastructure across AWS, Azure, and GCP. I led migrations to Snowflake and BigQuery, drove a platform overhaul that cut pipeline costs 25%, and built real-time ingestion pipelines reducing latency by 60%.
I design end-to-end MLOps/LLMOps systems—feature stores, CI/CD, observability, and governance—mentoring teams to deliver compliant, production-grade AI solutions. I champion platform modernization, reverse ETL, and secure data practices to enable actionable analytics and faster product delivery.
