Data Engineering and Oracle specialist with 11+ years of hands-on experience designing, building, and managing enterprise data pipelines, cloud migrations, database infrastructure, and analytics platforms at scale.
I bring deep expertise across the full data lifecycle — from database administration and real-time replication to building modern ETL frameworks, interactive data platforms, and self-service analytics dashboards. I've worked extensively with Oracle (SQL/PL/SQL, DBA, Golden Gate, RMAN, ODI, Data Guard, ZDM), cloud platforms (Oracle Cloud, Google Cloud/BigQuery), modern data engineering stacks (Apache Spark, Python, Docker), and BI/visualization tools (Apache Superset, Tableau, Cognos).
Most recently, I architected and built NexusFlowETL — a production-grade, containerized ETL framework powered by Apache Spark and Python that automates data integration across Oracle, BigQuery, MySQL, and file-based sources (Avro, Parquet, CSV, JSON). It features a Streamlit-based web UI for job management and real-time monitoring, checkpoint-based fault tolerance, secure Oracle Wallet and GCP service account integration, and is deployed on OCI Container Registry via Docker.
Whether you need a complex database migration with zero downtime, a scalable ETL pipeline, a cloud data warehouse integration, or an Apache Superset deployment for self-service analytics — I deliver reliable, production-ready solutions.
