Hasi Iqbal

I’m a Senior Data Engineer with 8+ years architecting distributed systems in Healthcare, Fintech, and SaaS. I focus on governed lakehouse architectures, multi-tenant isolation, and HIPAA-compliant clinical data modeling—turning complex data requirements into reliable pipelines.

I specialize in transitioning legacy batch workflows to event-driven streaming, enforcing DataContracts, and delivering measurable FinOps cost optimization. From windowing and stateful processing to idempotent SQL transformations, I design for correctness under real-world data volatility.

In my recent work, I’ve built multi-cloud Lakehouse platforms using BigQuery and Databricks (Delta Lake), using UnityCatalog for cross-platform governance and SQL row-level security for strict multi-tenant isolation. I’ve also operationalized data quality and observability with Great Expectations and MonteCarlo, integrated directly into Airflow DAG lifecycles to programmatically enforce contracts.

I’m equally comfortable in the “platform” layer—Infrastructure as Code with Terraform/Pulumi, IAM policy design, KMS encryption, and secure resource lifecycle management through CI/CD. Whether it’s PHI ingestion with KMS key rotation on AWS S3 or real-time reconciliation using Debezium and exactly-once semantics, I bring a technical, security-first mindset to every delivery.
