Data Engineer at Kamakhya Analytics, overseeing ATLAS pipelines and designing a PostGIS geographic data model.

Message

At Kamakhya Analytics, I oversee ATLAS pipelines after their move from Varahe Analytics, including 100+ dbt models and an API serving 10k+ requests per day. I’m designing a PostGIS database that maps 10 geographic layers into one master table.

At Varahe Analytics, I led data architecture for ATLAS, a political intelligence platform, from AWS setup through delivery of an API serving 10k+ requests per day. I built a 5TB+ Snowflake warehouse with 100+ dbt models and provisioned a 60+ table PostgreSQL database on AWS RDS.

At Tech Mahindra, I reduced latency by 15% across three data workflows through pipeline refactoring and SQL query tuning. At OATI, I delivered incremental MongoDB-to-MSSQL replication with Apache NiFi and replaced per-collection code with a metadata-driven pipeline covering 20+ collections.

At Agilon Health, I improved efficiency by 45% with an Azure Databricks and PySpark lakehouse pipeline for 10M+ Oracle clinical records. I also worked on HL7 and FHIR data integration, including streaming API records into Google BigQuery and migrating legacy clinical data.
