What I'm looking for

I seek a collaborative role building scalable, cloud-native data platforms and pipelines, emphasizing governance, cost optimization, and productionizing analytics and ML.

I am a seasoned Data Engineer, Architect, and Senior Data Analyst with over 10 years of experience designing and delivering cloud-native data platforms, data lakes, and enterprise data warehouses across AWS, Azure, and GCP. I build scalable ETL/ELT and streaming pipelines using Spark, Kafka, Airflow, dbt, and Snowflake to enable analytics, ML, and business intelligence.

My technical strengths include advanced Python and SQL, Spark batch and streaming, Kafka, Delta Lake, and extensive experience with Snowflake, Redshift, and BigQuery. I have driven migrations, cost optimizations, and productionization of models with MLflow and SageMaker while leading governance, lineage, and compliance initiatives (HIPAA, GDPR).

I thrive in collaborative, fast-paced environments where I can mentor teams, standardize data modeling practices, and deliver high-impact dashboards and insights using Tableau, Power BI, and Looker to support strategic decision-making.
