I need a single-page website that spotlights my new WhatsApp API service and drives visitors to try it. Starting from a blank canvas, please craft a layout that feels both modern and professional—clean typography, generous white space and subtle animation are welcome, but usability must stay front-and-centre. Core sections I have in mind: a punchy hero with headline, benefit-oriented feature blocks, at-a-glance integration diagram, lightweight social proof, and a decisive call-to-action button that links to our signup endpoint. Colour palette can take cues from WhatsApp green yet still look distinct, and everything must be fully responsive so it feels native on mobile. Deliverables • High-fidelity design file (Figma, XD or Sketch) • Production-ready HTML/CSS (Bootstrap, Tailwind or vanilla) that mirrors the approved design • Any assets, icons or illustrations used, neatly organised I am only reviewing bids that showcase relevant experience creating SaaS or API landing pages—please share a concise portfolio or live links that prove you can balance aesthetics with conversion-focused structure.
