Featured Projects

Eight end-to-end case studies applying Python, SQL, predictive modeling, and strategic frameworks to logistics, demand, supplier, and inventory challenges.

Operations Platform

Logistics Command Center

End-to-end diagnostic on 2,500 shipments across carriers, zones, and routes. Used Pandas for cleaning and K-Means clustering to segment carrier performance by OTD — surfaced an estimated 15% cost-reduction lane.

SKU Demand Forecasting

Time-series forecasting across 20 SKUs over 24 months. Cleaned 14,620 daily demand rows and deployed interactive 3-month SMA models with MAPE computed live from a held-out test split — no resume-bait hardcoded numbers.

Supplier Performance Dashboard

Supplier scorecard built on SQL aggregations evaluating cost variance, delivery reliability, and quality. Used as a benchmarking layer to drive 98% compliance and surface vendor-renegotiation opportunities.

Inventory Analytics Dashboard

ABC-XYZ classification driving differentiated turnover targets — 6–12x for Class A, 1–3x for Class C — with reorder-point optimization and a strategic recommendations panel for action items.

About

A bit about me

I work at the intersection of operations and analytics — translating supply chain problems into models that decision-makers can actually use.

Status● Open to roles

My work spans demand forecasting, inventory optimization, and supplier intelligence — the three levers that quietly decide whether a supply chain costs too much or breaks at the wrong moment. I'm most useful when the data is messy, the question is fuzzy, and someone needs a defensible answer by Friday.

I lean on Python (Pandas, NumPy, scikit-learn) and SQL for the heavy lifting, then surface results in Tableau, Power BI, or — as on this site — purpose-built front-ends so the analysis stays accessible after the slide deck closes.

I hold certifications in Supply Chain Analytics (Rutgers) and Supply Chain Data Analytics (Unilever), and I'm currently completing a BBA from Manipal University Jaipur. These combined with hands-on projects are how I bridge theory and real operational problems.

Outside the dashboards: I read research on procurement strategy, write up case studies on SCData.ai, and keep a running list of supply chain failure modes that should never have made it past the planning phase.
