Minimalist Responsive App Showcase Site

I need a modern, mobile-friendly website that keeps a clean, minimalistic look while putting our two flagship apps front and centre. The first section will introduce the company in a few short paragraphs. From there, visitors should flow straight into the app showcases, each with its own page or panel that contains:

• A brief feature description written for end-users
• A Google Play download button (I’ll supply the URLs)
• An image carousel; all screenshots and promo graphics are ready to upload

The layout must scale smoothly from desktop down to small phones, with the carousels retaining swipe support. I also want the structure to be future-proof, so I can easily add more apps—or even short films—without redesigning everything. A lightweight CMS or clearly commented HTML components are both fine as long as the edit path is simple.

Please handle the complete build: wireframes, responsive front-end, and whatever CMS or static-site generator you recommend. Once finished, hand over all source files, assets, and a quick update guide so my team can publish new showcases on their own.
