I designed a complete data monetization SaaS platform where institutional clients could discover, preview, purchase, and download African economic datasets. I created tiered subscription access (free preview, standard, premium, enterprise) that allowed clients to explore before committing, built data preview interfaces so buyers could see sample data before purchasing, designed flexible export options (CSV, JSON, Excel, API access), integrated billing and subscription management, added usage analytics so clients could track their data consumption, and created a discovery interface with search, filters, and recommendations. The platform needed to feel professional enough for Morgan Stanley while remaining accessible to smaller African investment firms.
