Investment research subscription platform
Investor dashboard with free research screens and a Stripe paywall for premium data.
3.5-year client relationship (2020–2023)
Challenge
Market feeds and scraped company data had to power the same screens without mixing free access with paid data.
Outcome
Dashboard live with stock charts, earnings, and research signals; premium access gated through Stripe.
My contribution
Split premium into data access, chart refresh, and upgrade steps. Kept client-supplied API signals separate from data the team had to scrape and normalize.
