devRoast — IT interview prep for developers
We shipped a multilingual marketing site and conversion path for a beta interview-prep product: honest positioning, real UI screenshots, i18n routing, and performance discipline so hero and sample cards stayed fast on phones.
Project overview
Interview prep competes with blogs and expensive coaches. devRoast needed a blunt developer-native narrative with concrete artifacts—sample questions, STAR scaffolding, quizzes—and a waitlist funnel that did not over-promise unreleased features. Our delivery covered fast first paint, hreflang-friendly structure, and layout stability when fonts and bundles load.
Client challenge
Multilingual marketing without maintenance nightmares; beta honesty without killing trust.
- i18n routing and hreflang-friendly structure across many locales
- Above-the-fold LCP on hero and sample question card
- Dark-theme readability and dense typography on small screens
- Waitlist funnel that converts without implying GA-ready features
- Layout shift containment when client bundles and fonts hydrate
- Screenshot-led proof that the product exists
