• Code Quality: a high standard for clean code, including modularity, readability, and adherence to modern ES6+ standards.
• Attention to Detail: ability to spot subtle logical flaws, memory leaks, or security vulnerabilities (e.g., XSS, prototype pollution) in model-generated code.
• Core Language: expert mastery of JavaScript (ES6+) and TypeScript.
• Frameworks: extensive experience with React, Node.js, Vue, or Angular.
• Testing & Tools: proficiency with Jest, Cypress, Webpack, and Vite.
