At Xtelify Ltd. (previously Airtel Digital), I own and stabilize Financial Services data workflows, improving reliability for reporting, product, and operations teams.
I refactored critical SQL reporting queries across roughly one million rows per day, reducing execution time by about 65%. I also built and automated 50+ CDC ingestion pipelines with Debezium, Oracle, MongoDB, Kafka, Apache Airflow, and AWS S3.
I partner with Data Science to build dbt transformation models that turn raw data into query-ready outputs. I use Python and PySpark validation checks to catch data-quality issues before they reach downstream reporting.
My work has earned Airtel's Execution Excellence Award and Customer Impact Builder Award for platform stabilization, reporting performance, and data accuracy.
