Resume Writing Tips for Frontend Engineers

1

Emphasize System-Level Thinking

Mid-level engineers own systems, not just features. Highlight: design systems built (50+ components), architecture decisions (state management migration), infrastructure improvements (build optimization). Show you think beyond individual tasks—you design how the team builds.

2

Quantify Performance and Scale

Performance optimization is key at this level. Include: bundle size reductions (40%), Core Web Vitals improvements (LCP, FID, CLS), load time gains (5.2s → 2.1s), user reach (2M+ users). Prove you understand performance at scale, not just on your laptop.

3

Show Architectural Decision-Making

Mid-level means making architecture choices. Include: state management strategies (Redux → React Query), component patterns (composition, render props), build optimizations (code splitting, lazy loading). Demonstrate you evaluate tradeoffs and choose appropriate solutions.

4

Demonstrate Cross-Functional Leadership

Mid-level engineers collaborate beyond their team. Include: design system adoption across teams, documentation enabling self-service, standards established org-wide, partnership with design/product/backend. Show you multiply your impact through enabling others.

5

Balance Breadth and Depth

List 12-15 skills covering frameworks (React, Next.js), languages (TypeScript), architecture (component design, state management), performance, testing, and accessibility. Show you're an expert practitioner with breadth across the frontend stack.

🎯

Essential Skills & Keywords
