CipherNova
Free numerology calculator, 12 languages, hand-rolled i18n with no dependency
Visit the site — CipherNova (opens in a new tab)
Context
A free, instant numerology calculator, with explanatory pages in twelve languages.
The challenge
Offering a fast interactive tool on mobile while keeping content pages fully static and indexable — without weighing the site down with an i18n library.
What I did
Hand-rolled i18n layer (JSON dictionaries, routing by language segment), dependency-free client-side calculations, static content, dynamic Open Graph image, segmented sitemaps and IndexNow notification on every deploy.
Technical highlights
- Hand-rolled i18n: JSON dictionaries, per-language routing, zero dependencies
- Instant client-side calculator, 100% static content pages
- Open Graph generated on the fly, segmented sitemaps, IndexNow
- Eight successive SEO audits to refine titles and descriptions
