Next-Showcase Overview

This site is a practical tour of my React and Next.js skills. Each page is a small, working feature you can read, try, and experience. The goal is simple, to let you evaluate my engineering approach, code quality, and product sense through real working examples and demos.

Everything is written in TypeScript with strict types, small composable components, and a predictable folder structure. The goal is for you to scan, open any feature, and quickly understand the approach with clear boundaries between data and presentation, and performance basics applied where they matter. These are features I can lift into real projects in an instant.

What you'll find

A hands-on tour of real product features built with React and Next.js. For example, client and server data fetching, TanStack Query caching with hydration and adjacent prefetch for fast page transitions, URL-aware pagination, and a debounced search that highlights matches. There are polished UI touches like controllable animations, date picking, loaders, and Markdown rendering. Authentication runs on Payload with Profiles and Accounts plus AuthSmith for social login, and there is a mailing flow and secure API routes. For AI, you can use Gemini directly or ask specific questions through a RAG setup backed by a File Search Store (trained AI). Everything focuses on practical UX, accessibility, predictable behavior, performance, and patterns that scale.

How I approach problems

• TypeScript first with strict types
• Small, composable components and clean folder structure
• Clear boundaries: hooks for data, options for queries, presentational components for UI
• Performance basics: React memo, debouncing, caching, prefetching, and image optimization
• Production-minded details: error states, loading states, empty states, and accessible controls

Personal Documentation

You can also visit jkturner.site for the bigger picture. The /tutorials section is my running build log, with short, practical notes I write while implementing features. It is organized like documentation but reads like real steps, including what I tried, what worked, common errors, and copy-paste snippets. It covers more than this showcase, including Next.js patterns, Payload and AuthSmith, TanStack Query, Gemini, mailing, storage, databases, and UI details. Use both sites together, try the feature here, then see the how-to and reasoning there.
