What I'm looking for

I'm looking to build scalable cloud data platforms, automate reliable ETL/ELT workflows, and deliver trusted analytics that improves business decisions.

At Infosys, I build banking analytics platforms on AWS, Snowflake, and Databricks, processing customer, transaction, and branch data through Bronze/Silver/Gold layers. I reduced incremental-load latency from six hours to 20 minutes and built data-quality automation that detects 200+ anomalies monthly.

Previously at Hitachi Payment Services, I engineered AWS Glue ETL pipelines for ATM transaction data, eliminating 10+ hours of weekly manual preparation for three business teams. I also built Airflow-driven alerts that reduced ATM cash-out resolution time by 75% across a 68K+ ATM network.

I enjoy turning high-volume operational data into reliable pipelines, governed data marts, and dashboards that support faster decisions.
