About Vishu Yadav
I’m a Data Engineer with a Computer Science background, focused on building reliable, scalable data pipelines and turning raw data into analytics-ready datasets. I’ve worked across ETL/ELT, data quality checks, automation, and performance tuning—helping teams get faster, cleaner insights.I’m exploring opportunities in Data Engineer / Data Analyst roles (open to adjacent roles where I can work deeply with data and analytics). If you’re building data platforms, pipelines, or BI-ready models, I’d love to connect.
