About Harsh Mahatma

I am a Senior Manager / Director-level Data Engineering leader with 14+ years of experience building, scaling, and operating enterprise data platforms and leading globally distributed data and analytics teams.My focus is on data platform strategy, lakehouse architecture, and real-time and batch data systems that support analytics, BI, and production ML and AI workloads at scale. I’ve led initiatives across Healthcare, Aerospace, Retail, Supply Chain, and Martech, including large-scale platform modernization and M&A data integration.I’ve owned end-to-end data platforms, from architecture and tooling decisions through delivery, reliability, and cost management. This includes designing and operating lakehouse platforms using Iceberg, Trino, Snowflake, dbt, Spark, Kafka/Kinesis, and Airflow, with production workloads processing hundreds of millions of events per day.In addition to analytics and BI, I’ve focused on enabling AI and ML use cases through strong data foundations, including real-time ingestion, feature-ready datasets, governance, observability, and cost-aware platform design. This work has supported production ML pipelines, AI-driven analytics, and agent-based automation by ensuring data reliability, lineage, and performance at scale.From a leadership perspective, I’ve built and scaled global teams, led hiring and performance management, partnered closely with Product, Engineering, and Executive stakeholders, and translated business goals into executable data roadmaps.My work has delivered measurable impact, including- Reducing data platform costs by 75% through architectural and operational optimization- Saving $150K+ annually by migrating legacy workloads to a modern lakehouse stack- Building real-time platforms processing 250M+ events per day- Improving incident MTTR by 85% through better observability and platform design- Delivering a $700M+ defense data platform recognized with a President’s AwardI am most effective in Senior Manager or Director roles where I can set platform vision, grow strong engineering teams, and deliver reliable, well-governed data systems that directly support analytics, AI adoption, and business decision-making.
