Startup ecosystems are built, not declared. A decade and 200+ repositories of evidence across six fronts: platforms and registries, access to capital, talent and education, the founder journey, original tools and IP, and trust engineering - all of it inspectable, none of it invented.
A TypeScript/Express/Mongoose data backbone for a student super-app: loans, jobs, service marketplaces, short video, communities, messaging, and transport booking - ~35 domain models mapping the entire economic life of a Nigerian student.
An interactive Python/Jupyter financial model for a Nigerian ISP business: ~15 tunable parameters (NGN pricing, data caps, COGS, capex, location capacity) driving live KPI and break-even visualizations.
A pandas/scikit-learn CLI that turns raw Kuda neobank statements into spending analytics: category and counterparty breakdowns, 3-sigma anomaly detection, and a 30-day cash-flow forecast - built for the messy reality of Nigerian bank exports.
