§ 01 / About

I'm Hari, a data engineer who cares about one thing above everything else: pipelines that run without drama.

My work is GCP-native: BigQuery, Cloud Composer, Cloud Storage, Data Fusion, Looker Studio. I like clean SQL that explains itself, idempotent loads, and dashboards a non-engineer can trust. Currently at Quantiphi Analytics.
