I build cloud data pipelines for large-scale retail and enterprise platforms.

I've built and optimized cloud ETL/ELT pipelines for large-scale retail and grocery enterprise clients, using dbt, Apache Airflow, Snowflake, Kafka, AWS, and Terraform across the full data lifecycle.

I develop Data Vault models, custom dbt macros and tests, Airflow hooks, operators, and sensors, plus CI/CD automation for Snowflake and dbt deployments. I've also implemented data-quality frameworks, Kafka Connect ingestion, monitoring and alerting, infrastructure provisioning, and Snowflake performance optimizations.

Earlier, I built FastAPI and Starlette REST APIs and real-time healthcare operations features backed by PostgreSQL and Snowflake. I'm an AWS Certified AI Practitioner, AWS Certified Cloud Practitioner, and Google Cloud Associate Cloud Engineer.
