Portfolio Site With Gallery Showcase

I need a clean, modern portfolio website whose single focus is displaying my work in a visually engaging way. The site’s core feature will be a project showcase presented as an image gallery—think responsive grid, light-box or slider for larger views, smooth transitions, and fast loading. I do not require a résumé, bio, or contact form at this stage, so every layout decision should prioritise the gallery experience.

You are free to choose the best stack—static HTML/CSS/JS, a React front end, or a lightweight CMS—as long as the finished site is:

• Fully responsive across desktop, tablet, and mobile
• Easy for me to add, remove, or reorder projects without touching code
• Optimised for performance and basic on-page SEO (clean semantic markup, alt text, etc.)
• Delivered with all source files and a brief hand-off guide

If you have existing gallery plugins or custom scripts that suit this purpose, feel free to propose them; I’m open to recommendations that keep maintenance simple while showcasing high-resolution images beautifully.
