Senior Front‐End Developer - FadiZahhar/ideas GitHub Wiki

A Senior Front-End Developer is a highly experienced software engineer who specializes in building the user interface (UI) and user experience (UX) of web applications — essentially, everything users see and interact with in a browser.

They go beyond just "making things look good" — they lead the architecture, performance, accessibility, and maintainability of the front-end codebase.

💼 Responsibilities of a Senior Front-End Developer:

🔧 1. Build and Maintain UI

  • Create responsive, accessible, and interactive interfaces

  • Use frameworks like React, Vue, Angular, or Svelte

  • Implement pixel-perfect designs from Figma, XD, or Sketch

🧠 2. Architecture & Code Quality

  • Design scalable and modular component architecture (e.g., atomic design, reusable components)

  • Set up and enforce coding standards (linting, TypeScript, testing)

  • Use state management tools like Redux, Zustand, Pinia, etc.

🚀 3. Performance Optimization

  • Improve page speed, load times, and rendering performance

  • Optimize asset delivery, lazy loading, and tree-shaking

  • Use tools like Lighthouse, WebPageTest, or Chrome DevTools

✅ 4. Testing & Reliability

  • Write unit, integration, and end-to-end tests using tools like:

    • Jest

    • Testing Library

    • Cypress or Playwright

  • Ensure code is stable and regression-free

🤝 5. Mentorship & Collaboration

  • Review PRs and mentor junior/mid developers

  • Work closely with UX/UI designers and back-end engineers

  • Help with sprint planning, estimates, and breakdown of tasks

⚙️ 6. Tooling & DevOps (light)

  • Set up and manage front-end build tools (Webpack, Vite, Rollup)

  • CI/CD pipelines for automatic testing and deployment (GitHub Actions, CircleCI)

  • Possibly Docker knowledge for dev environments
