SweatUp

Problem

Nutrition and health goals need a product that can take payments, talk to many APIs, and stay fast when the same reads hit over and over.

What I built

• SaaS app in Next.js with a Node.js/Express API
• PostgreSQL data model for users, goals, and nutrition records
• Redis cache for hot REST responses under 100ms
• Stripe payment flows for subscriptions

Outcome

A personal SaaS stack for nutrition and health goals — paid, cached, and wired to the APIs it depends on.
