Isaac Neibaur's public sprint to turn disciplined data engineering practice into useful dashboards, shipped one day at a time.
About The Project
Challenge
Build 100 dashboards in 100 days
The challenge is designed to develop consistency, rapid-response data skills, and practical data storytelling by repeatedly moving from question to real dataset, analysis, visualization, and published dashboard.
Tech
Python + Astro + Cloudflare monorepo
The stack stays intentionally local-first and reviewable while supporting reusable Python dashboard logic, Markdown publishing, and static web delivery.
Tooling Range
Broad dashboarding practice over time
The project will intentionally explore a wide range of dashboarding tools, platforms, and standards, including Power BI, Tableau, Cognos, Oracle, Google Analytics, Azure, AWS, Supabase, Google Sheets, Excel/CSV, and real public APIs where low/no-cost options are practical.
Data Standard
Real data whenever possible
Dashboards should use real data rather than mock data whenever possible, with source context, limitations, and assumptions made visible enough for readers to understand what the dashboard can and cannot claim.
Engineering Rigor
CI/CD, validation, security, and coverage
Each meaningful change is expected to stay compatible with CI/CD, metadata validation, security checks, and the project coverage gate of at least 80% for modified reusable logic.
