As a developer, your portfolio is your handshake with the engineering world. It’s tempting to throw together a quick HTML page with static bullet points of the languages and frameworks you know.
But as your stack grows and your projects shift, hardcoding lists of skills across multiple page sections becomes a maintenance nightmare.
In this quick guide, we’ll build a dynamic Technical Ecosystem component in React and TypeScript. We'll define our skills once in a single data configuration, render them in an interactive filterable list, and automatically feed them into a dynamic "Ecosystem Card" elsewhere in our app.
🛠️ The Architecture: Single Source of Truth
We want to achieve a Single Source of Truth pattern. When we add a skill or adjust our proficiency level, we want all layout cards, timelines, and filter chips to update automatically.
Here is the folder structure we'll use:
text
src/
├── types.ts # Type boundaries
├── data.ts # Central skills & projects configuration
└── components/
├── Skills.tsx # Filterable technical catalog
└── Summary.tsx # Dynamic ecosystem grouping card
