What I'm looking for

I’m looking to build and own production-grade real-time and batch data pipelines, focusing on data quality, validation, and root-cause problem solving. I want to work end-to-end with Spark/Python on AWS and collaborate to improve reliability for downstream consumers.

I like making things work—building pipelines from scratch and digging into what went wrong when records don’t add up. I’ve spent almost four years at PwC India shipping production data systems, with a strong focus on the data that sits downstream of everything I build.

Across real-time and batch workloads, I’ve designed ingestion and validation layers, performed root-cause analysis on data inconsistencies, and backfilled long histories to keep consumers trusted. I work across Python, Spark, AWS, and Airflow, and I’m energized by the problem solving in between the tools, whether that’s optimizing DynamoDB indexing, accelerating transformations, or improving dataset readiness for ML training and inference.
