# Tisha S Jain on Tal

## Headline

Data Analyst \| SQL, Python, Power BI, Tableau, Excel \| Retail & Supply Chain Analytics \| A/B Testing, KPI Dashboards \| IBM Certified Data Science

## About

I'm a Data Analyst who helps retail and supply chain teams decide what to stock, promote, and fix\. I work in SQL, Python, Power BI, and Tableau, specializing in KPI dashboards, sales and inventory analysis, A/B testing, and demand tracking\. I started in retail at Decathlon, where I tracked 2,000\+ SKUs and learned to build every analysis around the decision someone has to make\. At Decathlon: • Analyzed seasonal sales in Power BI, supporting campaigns that increased mountaineering product sales by 150%\. • Ran an A/B test that lifted store footfall by 55%\. • Built demand and inventory dashboards that helped cut stockout\-related losses by 30%\. Since then, freelance work in Python and NLP has cut report turnaround by \~30% and manual feedback analysis by 35%\. IBM\-certified in Data Science\. Reach out if you're hiring Data or Business Analysts, or need sales, inventory, or customer data turned into clear recommendations\.
