What I'm looking for

I seek a senior engineering or architect role building scalable, compliant cloud data platforms, leading end-to-end initiatives and cross-functional teams to deliver analytics and ML-ready data.

I am a results-driven Senior Data Engineer and Solution Architect with over 8 years of experience designing, building, and managing scalable, high-performance data infrastructure across cloud-native and on-premises environments. I specialize in architecting modern data lakes and warehouses, building robust ETL/ELT and real-time pipelines, and enforcing data quality and governance in regulated industries such as healthcare.

My hands-on technical toolkit includes Python, SQL, Apache Spark, Airflow, dbt, and cloud platforms like AWS and GCP; I have led end-to-end initiatives (including multi-cloud lakehouses, real-time Kafka/Spark pipelines, and large-scale migrations to Snowflake/Databricks) that reduced latency, improved predictive accuracy, and ensured compliance while lowering costs.
