What I'm looking for

I’m looking for dynamic work where I can design and deliver end-to-end data pipelines on cloud platforms—ensuring clean, validated datasets that enable analytics, dashboards, and predictive modeling.

I’m a Senior Consultant in Technology and Transformation at Deloitte with 8 years of experience spanning analysis, design, development, and implementation. I focus on building secure, scalable data platforms that turn core system data into well-modeled, analytics-ready datasets.

I’ve implemented AWS-based data lake solutions for core banking use cases, extracting data into Bronze (Parquet on S3), building Silver layers with AWS Glue ETL and Delta Lake merge upserts, and delivering curated Gold datasets for reporting and predictive analytics. I also work across PySpark, Athena, Airflow, and validation/output modules to ensure data integrity, operational reliability, and smooth delivery through SIT/UAT to staging and production.
