Flagship Project
Sungnikah — From idea to production SaaS
A digital wedding invitation SaaS that I built from scratch, evolving from a static website into a dynamic, API-driven platform. Couples can create personalized invitations, manage guests, and publish shareable pages with unique themes.
Problem
- Traditional wedding invitations were static and hard to customize
- No scalable content system for couples
- Managing themes, media, and guests manually was time-consuming
Solution
- A multi-tenant SaaS with per-couple customization
- Dynamic theme system that renders unique wedding pages
- SEO-friendly SSR, media upload, and guest management
Engineering Challenges
- Dynamic theme architecture
- Multi-tenant data isolation
- Image and media management
- SEO & SSR at scale
- Deployment, backup, and monitoring
