Data Visualizations
Dashboards from the pipelines
The same kind of executive dashboards I build in Power BI and Tableau, rebuilt here as fully self-hosted, interactive visualizations. Every chart is rendered in your browser with Apache ECharts over data generated from the three projects' own data generators — no third-party BI service, no license, just static JSON on GitHub Pages.
Tip: toggle the theme (top-right) — the charts restyle live. Numbers are synthetic and seeded; they illustrate the shape of the data, not production figures.
Dashboard 01 · Telecom revenue & churn
Telecom Billing Lakehouse
Revenue, ARPU, call-mix, and churn marts derived from 50,000 rated Call Detail Records — the Gold layer of the Medallion lakehouse, visualized.
Dashboard 02 · Real-time fraud analytics
Fraud Signals
Fraud-rate, geography, pattern mix, and streaming throughput from the synthetic transaction producer feeding the Spark/Delta pipeline.
Dashboard 03 · Query optimization benchmark
AI-Assisted SQL Optimizer
Cost-reduction and analyzer-finding benchmarks across the 50-query optimization corpus.
