What I'm looking for

I'm targeting hands-on Data Engineering Manager and Data Platform Lead roles focused on technical direction, team enablement, and reliable delivery.

At Oracle, I own architecture and production integration for a large-scale, multi-service data platform while staying hands-on with distributed processing, data products, reliability, and cloud operations. I re-engineered PySpark workloads to reduce a key processing cycle from days to under four hours, lower infrastructure costs by about 60%, and support reliable TB-scale weekly processing.

I've built reusable ingestion, CDC, streaming, geospatial, and ML feature-engineering platforms using Spark, Kafka, Airflow, Debezium, OCI, Kubernetes, and PostgreSQL. My work spans Oracle, CNSS, and FEEN Technologies, where I turned machine-learning prototypes, real-time applications, and enterprise pipelines into production tools people use.
