Senior Data Engineer at Sigmatic Analytics building Snowflake data models and Databricks geospatial pipelines.
PakistanWhat I'm looking for
At Sigmatic Analytics, I architected Snowflake Data Vault models for Aviva Group’s motor data and developed dbt pipelines for staging, consolidation, and transformation.
For Mural, I optimized geospatial processing of GeoJSON and GPKG datasets in Databricks, building medallion pipelines with Apache Sedona and DAB for CI/CD.
At Softsincs, I designed an AWS data pipeline for AP News using S3, EMR, and PySpark. For Akumin, I shifted pipelines to incremental processing, reducing costs by 70%, and built dbt models across Bronze, Silver, and Gold layers.
At Digifloat, I migrated Fertiglobe pipelines to Microsoft Fabric and centralized Trescal records in OneLake. I also optimized LawGPT’s legal search platform on Azure, reducing document retrieval time from 10–16 seconds to nearly 2 seconds.
