Blog Site with Social Integration

I’m launching a personal blog and need a full website built from the ground up. The core requirements are:

• A clean, responsive layout that looks great on desktop and mobile.
• A user-friendly CMS (WordPress, Ghost, or a comparable platform) so I can add posts without touching code.
• Seamless social media integration—readers should be able to share articles instantly and I’d like my feeds or share buttons displayed elegantly on every post.

I already have hosting and a domain; you’ll handle installation, theme customization, and any essential plugins. Please deliver a ready-to-publish site, provide brief walk-through notes, and make sure everything is optimized for speed and basic on-page SEO. If you have a portfolio of similar blog builds, that will help me decide quickly.
