What I'm looking for

I seek senior-level roles building scalable, secure cloud data platforms with opportunities to lead migrations, drive governance, and mentor teams.

I am a results-driven Senior Data Engineer with over 7 years of experience designing, building, and optimizing large-scale data pipelines and modern data architectures across healthcare, insurance, and retail sectors.

I specialize in AWS-centric cloud ecosystems while contributing to Azure and GCP environments, implementing secure data lakes, data warehouses, streaming platforms, and AI/ML-ready pipelines that improve performance and compliance.

My hands-on achievements include Redshift optimization that reduced query latency by 60%, migrating on-prem Hadoop to EMR with Spark tuning and autoscaling, and cutting processing times by 55% through PySpark transformations on Databricks.

I lead cross-functional initiatives in data migration, governance, DevOps for data, and cost optimization while mentoring teams and driving multi-cloud interoperability, observability, and secure, production-grade CI/CD for data workloads.
