At Foodelity Group GmbH, I built Python and SQL scripts that unified POS and delivery-platform data, reducing pipeline errors by 15% and administrative reporting time by 20%.
I developed SQL inventory audit models to reconcile freezer counts with POS recipe data, lowering food waste and operational overhead by 12%. I also created a labour-scheduling model and a Power BI Menu Engineering Matrix to support store decisions.
For multi-city expansion across Germany, I architected a dual-schema reporting structure and led A/B menu tests, establishing more than eight local KPIs and a repeatable BI playbook.
On the CarRathi freelance project, I built full-stack features across customer, driver and admin workflows, and implemented security checks. I also developed E-commerce Data Warehouse & Analytics and BusinessLens AI, including ETL pipelines, KPI dashboards and an AI-assisted analytics app.
