In this tutorial, self‑taught data scientist Kedeisha Bryan demonstrates how to use Google’s Gemini Spark AI agent to create a complete, high‑value data analyst portfolio project focused on supply chain logistics. She begins by prompting the agent to source a real‑world dataset (USAID Global Health Supply Chain), then reviews the automatically generated star‑schema (shipment fact table with product, vendor, and geography dimensions). After a brief data‑quality audit that uncovers mixed data types, missing values, and ambiguous commodity cost fields, she directs the agent to clean and engineer features (e.g., a binary delivery flag, freight‑cost categories). The core analysis centers on operational bottleneck analysis: on‑time delivery rates, country‑level delay rankings, and mode‑of‑transport performance, revealing that the program falls short of its 85 % SLA (global OTD 74 %) and that delays stem from upstream processes rather than transit speed. Kedeisha iteratively refines visualizations, converting pie charts to bar charts, simplifying dual‑axis plots, and applying consulting‑style (BCG/McKinsey) aesthetics. She also creates a one‑page portfolio deliverable in Google Docs/PDF, highlighting key findings, schema diagrams, and bottleneck visuals. Throughout, she comments on the agent’s real‑time interaction limits, the need to manage the AI’s output, and the value of using AI to source high‑impact projects versus generic Kaggle datasets. The video ends with a call to action for coaching services.
