What I'm looking for

I’m looking to lead enterprise cloud data platform builds—ETL/streaming, architecture, and performance tuning across Azure/GCP/Hadoop—partnering with teams to improve reliability, latency, and data quality.

I’m a Senior Data Engineer with 8+ years architecting enterprise-scale data platforms. I’ve built 1PB+ data lakes and run high-throughput ETL pipelines processing 50TB+ daily and 1B+ events, improving pipeline reliability by 50% and reducing latency by 30%.

I specialize in cloud migrations, real-time streaming, and distributed systems optimization across Azure, GCP, and Hadoop ecosystems. From designing zero-data-loss Hadoop migrations to leading orchestration with Airflow, I turn complex business requirements into scalable, maintainable data architectures.
