Dual-Mode SaaS Landing Page Design

My digital business-card SaaS needs a show-stopping landing page presented in both dark and light themes. I’m aiming for the same modern energy you’ll see in this reference: https://dribbble.com/shots/25105765-Finance-SaaS-Landing-Page.

Color direction
Dark version: very-dark grey foundation with blue-to-purple gradients for contrast.
Light version: the palette can flip to soft neutrals while keeping the same blue/purple accents so the brand feels consistent in either mode.

Visual tone
Professional and sleek—something that feels premium rather than playful, with generous white-space, crisp typography, and smooth micro-interactions.

Key sections I want highlighted:
• Product showcase
• User testimonials
• Pricing plans

Deliverables
• Two complete landing-page designs (dark and light) in a single Figma file, organised with components, auto-layout, and named layers.
• Layered PSD exports of both themes for anyone on my team still using Adobe.
• Desktop (1440 px) and a mobile breakpoint, each following an 8-point grid.
• All fonts, colour styles, illustrations or icons you create bundled at hand-off.

I’ll review against the reference link, colour fidelity, and how smoothly the design scales from desktop to mobile. Once signed off, I’ll handle development on my end; I just need the pixel-perfect visuals to get started.
