What I'm looking for

I'm looking to apply SQL, Python, data-quality investigation, anomaly analysis, automation, and stakeholder reporting to data analytics roles, including opportunities in logistics where I can quickly learn the domain.

At Cognizant, I supported ANZ Plus reporting for an 850K+ customer banking platform, using BigQuery SQL across transaction and customer data to maintain 99%+ accuracy. I built SQL and Python validation pipelines that reduced routine data-quality checks by about 30% and Power BI dashboards that helped reduce failed transactions by roughly 15%.

I'm continuing applied AI/ML training while building live Streamlit analytics applications, including IPL, e-commerce, and YouTube Shorts prediction projects. I also revived and run my family's stone mining and crushing business, managing operations, compliance, and accounts end to end.
