LongevityGreenLight

Inspiration

Most people know what keeps them healthy and rested — they just don't do it in the moment. I wanted a product that trains the reflex, not the knowledge.

What it does

A browser game that trains your reflexes to choose longevity on autopilot. You take a quick free check, see where you stand, then play the full game to turn better choices into instinct.

How I built it

Front end scaffolded with Vercel v0 (Next.js) and deployed on Vercel. The back end runs on Amazon DynamoDB, which stores buyer records and gates access to the paid game. Payments and transactional email connect through serverless API routes.

Challenges I ran into

Wiring a clean, idempotent payment-to-access flow so a verified purchase reliably unlocks play, with no double-counting.

What I learned

DynamoDB's single-digit-millisecond reads and conditional writes made the unlock-and-play loop simple to keep correct under load.

What's next

Tuning the funnel — free check to full game — and scaling the same stack to a companion deep-sleep title.
