What I'm looking for

I want to own end-to-end production data and streaming systems—building ETL pipelines and real-time IoT telemetry that meet SLAs, protect data quality, and reduce cost and latency.

I maintain multiple concurrent ETL pipelines for a healthcare client at Zimetrics Technology, delivering audit-ready data with zero missed SLAs. By profiling and rewriting PySpark jobs, I cut pipeline processing time and infrastructure cost by 80%, saving $500/month and unblocking downstream teams.

I built a fault-tolerant orchestration layer with AWS Step Functions, taking manual-intervention incidents from weekly to zero across 12 months. I also automated data-quality validation on PySpark transforms to eliminate silent failures that previously required manual remediation.

I architected a real-time IoT fleet telemetry platform tracking 500–1,000 vehicles per fleet with sub-60-second latency, using AWS IoT Core, Kinesis, and Lambda. I shipped serverless streaming and geofencing/alerting, and integrated Google Maps APIs for live visualization and route optimization.
