Pair each verb with scope and a metric: latency, uptime, deploy frequency, test coverage, cost reduction.

• "Built CI/CD pipeline (GitHub Actions) cutting release cycle from weekly to daily"
• "Designed REST and GraphQL APIs serving 2M+ requests/day with 99.9% uptime"
• "Led migration from monolith to microservices on AWS ECS"
• "Improved test coverage from 42% to 88% across core payment services"

Common keyword mistakes

• Skills dump — 30 technologies with no context in Experience
• Buzzwords without metrics — "cloud-native synergies" instead of "migrated 12 services to AWS Lambda"
• Wrong title — "Code Ninja" instead of "Software Engineer" or "Backend Developer"
• Synonym mismatch — resume says "JS" but posting requires "JavaScript"
• Design-heavy PDF — keywords trapped in graphics parsers cannot read
