Dark Animated Landing Page Build

I’m putting together a single-page marketing site with a clean, modern-dark aesthetic built only with HTML, CSS and vanilla JS. The hero section needs an animated grid-line background and a tab switcher that flips between two audience views, each showing the relevant product overview. From there the flow moves through a stats bar, a five-step “how it works” strip, six feature cards, and finishes with a pop-up modal that houses two sign-up forms.

Both forms must validate on the client side and push data into Google Sheets via Google Apps Script; I already have the sheet and script shell prepared. Smooth scroll-triggered animations, a custom cursor, Google Fonts over CDN and full responsiveness are required, and the build has to look identical across all major browsers.

Code needs to be clean, well commented and easy for me to extend. I can hand you the full brief and reference file as soon as I shortlist. When you reach out, send two or three links to dark or otherwise modern landing pages you’ve coded, confirm you’ve handled Google Sheets form integrations before, and let me know your price and how soon you can begin.
