At MintsClub, I modernized a legacy on-premise data warehouse to Snowflake on AWS, reducing query times by 60% and infrastructure spend by approximately 35%. I also architected a Databricks and Delta Lake lakehouse for batch and streaming analytics.
I built and scheduled more than 100 Apache Airflow DAGs and engineered Kafka and Spark Structured Streaming pipelines processing more than 5 million events daily with sub-minute latency. I introduced dbt star-schema marts and semantic models, shortening report development by 40%.
Earlier, at Clinix360, I maintained healthcare ETL/ELT pipelines and developed Spark and PySpark jobs on AWS EMR for patient and claims data. At InvoZone, I developed data-processing solutions and ETL workflows across on-premise and early-cloud environments.
