Data Engineer at FitchRatings improving data accuracy by 30% with automated validations and anomaly detection.

At FitchRatings, I implemented automated validations and anomaly detection that improved data accuracy by 30% in compliance-driven workflows.

I also strengthened data privacy and PII handling across pipelines, and reviewed SQL scripts and documentation for data lineage and privacy adherence.

Using Amazon S3 and AWS Glue, I orchestrated ingestion and transformation of over 10 million records weekly. I optimized Snowflake queries and Apache Airflow workflows, reducing data processing time by 25%.

At Amazon, I enhanced over 20 AWS Glue ETL jobs to detect and resolve anomalies, reducing manual error investigations by 40%. I also implemented least-privilege IAM roles and access controls across data workflows.
