VIKAS SINGH

I’m a SnowPro Core Certified Data Engineer specializing in enterprise Redshift-to-Snowflake migrations, ETL/ELT platforms, and data validation frameworks. I help teams move large analytical workloads with integrity, reliability, and measurable performance gains.

In my current role as an Associate Consultant – Data Engineering at Hakkoda (IBM), I’ve led migrations converting 25,000+ SQL queries and 8,000+ database objects. I’ve migrated production datasets from 10M to 5B+ rows while maintaining data integrity and platform reliability.

I optimize Snowflake SQL workloads and warehouse configurations to cut aggregation runtime from 9 to 2.5 hours. I also design scalable ETL/ELT pipelines using Snowflake, Python, Java, and AWS, and build reusable utilities to handle legacy date/time compatibility issues.

I’m especially proud of the systems I’ve built for confidence and speed: a configurable Patch Installer with rollback and dependency validation, and an enterprise data validation framework covering schema, row-hash, statistical, query-level, and custom SQL validation. By automating deployments, I’ve saved 30+ engineering hours weekly and improved platform stability by 45–50%.
