Modern WordPress Blog Setup

I need a fresh, modern-looking blog added to my existing WordPress site. The project covers everything from turning on the blog module through to a polished, responsive front end:

• Blog listing page styled for a clean, contemporary feel that matches my current branding
• Single-post template with author box, featured image, social share icons and a “You may also like” / related-posts section
• Category and tag structure set up—initial focus is on a Technology category, yet I want the framework left open for future Lifestyle or Business topics
• SEO-ready hierarchy: correct heading levels, schema, optimised permalinks, and fast-loading images
• Fully responsive layout that looks great on phones and tablets
• Up to 10 existing or placeholder posts imported and formatted so I can see everything in action

Please build with native WordPress blocks (Gutenberg) or a lightweight theme builder if that speeds delivery, and feel free to recommend plugins for caching and on-page SEO. Once complete, I should be able to add new categories, tags, and posts without touching code.
