Building a Case Study System Instead of a Project Gallery
How I designed a schema-backed project case study architecture in Next.js to provide verified technical proof for freelance clients.
01. THE CONTEXT
Standard web galleries show thumbnail images and bullet points. They fail to explain why a project was built, what problems were solved, what architectural decisions were made, or what source code supports the claims.
02. THE APPROACH
I replaced generic gallery cards with a structured, schema-backed case study system. Project data is defined in `data/projects.ts` using a strict TypeScript `Project` interface. Dynamic App Router routes (`app/projects/[slug]/page.tsx`) render comprehensive case study documents detailing Problem, Approach, Technical Execution, and The Resulting System.
03. THE IMPLEMENTATION
The case study architecture separates project data definitions from layout rendering components.
Centralized TypeScript Project Schema
Every project in `data/projects.ts` includes structured technical attributes: slug, title, category, shortDescription, description, technologies, whyItExists, problem, approach, implementation, result, and lessons.
export interface Project {
slug: string;
title: string;
category: string;
shortDescription: string;
description: string;
technologies: string[];
liveUrl: string | null;
githubUrl: string | null;
whyItExists: string;
problem: string | null;
approach: string;
implementation: string;
result: string;
lessons: string | null;
}// Strict interface definitions enforce consistent engineering documentation across all portfolio case studies.
Static Route Generation & Layout Decoupling
Static params generation statically compiles every case study at build time, while delegating visual layout rendering to the shared `CaseStudyBody` component.
export async function generateStaticParams() {
return projectsData
.filter((project) => project.slug !== "modern-calculator")
.map((project) => ({ slug: project.slug }));
}
export default function ProjectPage({ params }: ProjectPageProps) {
const project = projectsData.find((p) => p.slug === params.slug);
if (!project) notFound();
return <CaseStudyBody project={project} />;
}// Static page generation delivers fast page loads while maintaining zero duplicate code across case study routes.
04. WHAT CHANGED (VERIFIED)
- ✓Replaced simple image grid galleries with a centralized TypeScript project data model.
- ✓Created dynamic case study routes with static page generation (`generateStaticParams`).
- ✓Added visible breadcrumbs and structured `BreadcrumbList` JSON-LD schemas to all project pages.
05. WHAT I LEARNED
- •Presenting real technical problems, trade-offs, and source code links establishes far higher credibility with potential freelance clients than simple image galleries.
- •Decoupling project data from rendering components makes adding future case studies fast and error-free.
