AI-powered Personalized Book Platform for Kids
Sustainability Reporting Platform
Dating and Travel app for Hawaii
https://hawaiidating.netAs lead developer, I built the platform end-to-end. On the engineering side: Next.js with SSR for SEO, PostgreSQL via Prisma for the data layer, NextAuth.js for authentication, and DigitalOcean Spaces for media storage. I designed the schemas for member profiles, content publishing, categorization, and engagement tracking, and shipped the admin tooling that drives the editorial workflow.
On the product and growth side, I defined the dual content + community model, established the four-pillar editorial structure (Travel, Island Life, Local Culture, Health & Wellness), and built the on-page SEO foundation (canonical URLs, Open Graph and Twitter card metadata, structured slug architecture, semantic article markup).
The platform serves Hawaii residents and the around 10 million annual visitors to the islands through a unified content-to-community funnel designed for compounding organic growth.
