How to Quantify Your Achievements on a Resume

Why Numbers Matter

Metrics prove business impact, help hiring managers compare candidates, and make your accomplishments memorable.

Common Metrics by Function

• Backend/Platform: latency (p95/p99), throughput, MTTR, error rate, infra cost
• Frontend/Product: conversion, activation, retention, NPS, a11y scores
• Data: AUC, F1, forecast error, freshness, adoption
• Security: vulnerabilities closed, time-to-patch, coverage, policy adherence

Before/After Transformations

Before: Responsible for CI/CD for web app.

After: Implemented parallel CI and caching; build time −52%, enabling 3× daily deploys.

Before: Built dashboards for sales.

After: Delivered cohort dashboards that identified high-churn segments, driving −11% churn via targeted playbooks.

Fast Metrics Framework

1. Pick one KPI your team/company cares about.
2. Establish a baseline (before); measure the after.
3. Add scale (users, data volume, services affected).

Quantification Checklist

• Each role has 2–4 bullets with numbers.
• When exact numbers are confidential, use safe ranges (e.g., “low seven figures”).
• Tie metrics to business outcomes, not only technology.
