Led the modernization of telecom analytics pipelines by moving legacy ETL into a cloud-native Snowflake and AWS stack, with a focus on reliability, modularity, performance, and faster decision-making for service intelligence.
What I owned
- Migrated legacy ETL workloads to AWS-native architectures using Amazon S3, Snowpipe, and Snowflake for scalable analytical processing.
- Built reusable dbt transformation layers with Jinja macros, schema tests, and incremental models to improve maintainability and trust.
- Designed warehouse models for telecom service intelligence, customer lifecycle analytics, and churn reporting with dimensional modeling.
- Orchestrated production workflows with Apache Airflow on AWS MWAA, handling retries, dependencies, and production reliability.
- Optimized Snowflake performance using clustering, incremental loading strategies, and warehouse tuning to reduce latency and compute cost.
- Integrated Snowpark and Cortex AI capabilities to modernize Python-heavy workflows and enable AI-assisted analytics directly in Snowflake.
