Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Field Service KPI Dashboard

Beginner

Build an interactive Streamlit dashboard that ingests historical service ticket data and visualizes key metrics - first-time-fix rate, MTTR, SLA compliance, technician utilization - with filtering by region, equipment type, and time period.

Predictive Maintenance Model for Industrial Equipment

Intermediate

Using a public IoT sensor dataset, build a classification model that predicts equipment failure within the next 7 days. Engineer temporal features from sensor streams, evaluate with precision-recall trade-offs tuned to the cost of false positives vs. missed failures.
