Why This Resume Works
Improving Lighthouse scores from 38 to 94 and reducing TTFB from 1.8s to 240ms demonstrates the kind of measurable performance expertise that separates senior developers from mid-level ones.
Serving 2.1M monthly users and processing 45,000 SKU updates per hour proves you build systems that work at production scale, not just in local development environments.
Leading a jQuery-to-React migration connects technical decision-making to business outcomes like conversion rate increases, demonstrating the business awareness expected of senior developers.
Section-by-Section Breakdown
Summary
Lead with your primary tech stack, years of experience, and the scale of applications you have built. Include a headline metric like user count or performance improvement to immediately differentiate your profile.
Skills
Organize into Frontend, Backend, and DevOps categories with specific technologies named. Senior web developer roles are heavily filtered by exact framework and language matches in ATS systems.
Experience
Pair technical implementations with business outcomes. The best bullets show what you built (React migration, caching strategy) and why it mattered (62% faster, 28% more conversions).
Education
A CS degree provides a foundation but matters less than your technical track record at the senior level. Include relevant certifications like AWS Solutions Architect if you hold them.
Key Skills for Senior Web Developer Resumes
Based on analysis of thousands of job postings, these are the most frequently required skills:
Common Mistakes on Senior Web Developer Resumes
- ⚠Listing Technologies Without Projects - A skills section with 40 technologies and no context is less convincing than 15 technologies demonstrated through impactful projects. Show what you built with each technology.
- ⚠No Performance or Scale Metrics - Writing 'built a web application' tells nothing about your capability level. Include load times, Lighthouse scores, user counts, or request volumes to establish the scale you operate at.
- ⚠Missing Business Impact - Senior developers must connect code to business outcomes. A resume focused purely on technical implementation without conversion rates, revenue impact, or user growth misses the strategic dimension.
- ⚠Ignoring Accessibility and Standards - WCAG compliance is increasingly a legal and business requirement. Not mentioning accessibility suggests you build for the happy path only, which is a red flag for experienced hiring managers.
- ⚠No Leadership or Mentoring Examples - Senior developers are expected to elevate their teams. A resume without code review contributions, mentoring activities, or architectural leadership reads as a mid-level developer's.
