Resume summary / title example

« Senior iOS & Android Mobile Developer — 8 years of experience on high-traffic consumer apps. I co-designed the architecture and delivered 4 published apps (totaling over 2 million downloads), cut average crash rate from 0.9% to 0.08%, and led the migration to SwiftUI/Jetpack Compose on a 150,000-line codebase. Tech lead for a 5-developer mobile team, focused on performance, quality, and user experience. »

Common mistakes to avoid

• ❌ Listing technologies without project context

  ✅ Replace "Proficient in Swift, Combine, CoreData" with "Built an offline-first sync module in Swift + Combine + CoreData for an app with 500,000 MAU." Context gives the skill weight.

• ❌ Omitting app usage metrics

  ✅ A tech recruiter or CTO wants to know if you've worked on real, high-traffic apps. Always include volumes (downloads, MAU, store ratings), even approximate, if you're under confidentiality constraints.

• ❌ Not mentioning technical leadership

  ✅ At a senior level, recruiters expect proof of leadership: mentoring juniors, architecture design, ownership of a technical roadmap, leading mobile guilds. Without this dimension, your resume reads like a mid-level profile.

• ❌ Confusing seniority with exhaustiveness

  ✅ A senior resume isn't an inventory of everything you've ever touched. Select the most significant, recent, or role-relevant projects. Two dense, targeted pages beat four sprawling ones.

Our tips for a standout resume

1. Feature your published apps right in the summary: it's your most compelling portfolio, and few developers do this explicitly on their resume.
2. Tailor the highlighted stack to the recruiter's priority platform: iOS-first, Android-first, or cross-platform; a generic resume is less convincing than a targeted one.
3. Quantify your technical impact: reduced crash rate, improved build time, increased test coverage, optimized network latency — numbers turn experience into achievement.
4. Keep it ATS-friendly: use a clean format without complex CSS columns or tables, and include the exact keywords from job postings (Swift, Kotlin, Flutter, React Native, CI/CD).
5. Include an active GitHub link or project portfolio: all else being equal, a candidate whose code can be reviewed has a clear edge.
