About me

Abhishek Singh

Senior Data Engineer

Senior Data Engineer with 3.5 years building cloud data architecture on Azure and GCP. I specialize in high-volume ingestion, T-SQL and PySpark pipelines, and resilient scraping infrastructure — turning raw data into analytics teams can actually use.

Over the last few years at Nuvoretail I've led the move from legacy SQL Server stacks to modern, cloud-native data platforms — designing Data Lake architectures on Azure, orchestrating PySpark pipelines, and standing up cross-cloud analytics on BigQuery. I care about pipelines that are resilient, observable, and boring to operate.

I'm happiest when a messy, petabyte-scale ingestion problem turns into a clean dataset that powers a dashboard people actually trust.
