Scalable SaaS platform with performance-first architecture
Prexmo (prexmo.com)
System context
Prexmo is a digital business card platform-shareable cards, contacts, QR and link-based sharing-for teams that need networking without paper. The product needed a public system that stays fast under real devices and scrutiny.
System problem
The marketing and acquisition surface paid an early client-side tax (large hero work, late LCP on mid-tier phones). Tags could fire before a clear consent path-bad for EU visitors and for enterprise evaluation. Crawl/index health needed one signal per URL across templated pages, not duplicate thin content.
System fix
Tightened the Next.js App Router delivery path-prioritized above-the-fold assets, image and font loading so LCP anchored on meaningful content, and gated non-essential scripts behind explicit consent. Standardized metadata and JSON-LD per template so crawlers read a single coherent system.
System outcome
Faster perceived load on real hardware (Chrome traces-not a fabricated headline %). CLS dropped after sizing discipline. EU visitors see analytics and marketing pixels only after an affirmative step; support noise on “random cookies” fell. Search Console indexing behavior for templates cleaned up once duplicate meta issues were removed-steady, not overnight.
