Tools: Lovable Cloud, Google Cloud API (Gemini 3.0), Stripe API
The Challenge
Creating a viral utility app for students targeting top-tier universities (Harvard, Yale, etc.) that offers immediate free value while monetizing premium advice.
The Solution
I developed an automated essay analysis tool using Lovable Cloud logic. The app provides a "roast" (critique) and a numerical rank for free, then utilizes a hard paywall for actionable improvement strategies.
Key Deliverables:
Automated Grading System: Prompted Gemini 3.0 via Google Cloud API to analyze text based on specific academic criteria (tone, structure, originality).
Freemium Architecture: Engineered a specific user flow: Input $\rightarrow$ Roast/Rank $\rightarrow$ Stripe Paywall $\rightarrow$ Pro Tips.
Secure Payment Webhook: Ensured the premium content is only unlocked upon successful Stripe transaction confirmation.
