About Me

Gourav Chawla - GCP Data Engineer

I'm a Data Engineer at Accenture with 4+ years of experience designing and building enterprise-scale data platforms on Google Cloud Platform. I specialise in Medallion Architecture, real-time ingestion pipelines, and cost-optimised cloud infrastructure — currently processing over 30GB of data daily across retail and banking domains.

Previously at Tata Consultancy Services, I led cloud data migrations, BigQuery optimisation, and Infrastructure-as-Code using Terraform. I'm a Google Certified Professional Data Engineer and a strong advocate for clean, maintainable pipelines and engineering best practices.

Beyond my day job, I actively mentor aspiring data engineers on Topmate — covering GCP, BigQuery, career guidance, and breaking into data engineering.
