Tips for a Backend Engineer resume

  1. Quantify scale and reliability: requests per second, latency, uptime, data size.
  2. Show ownership: services you designed, not just tickets you closed.
  3. Mention incidents you resolved and what you changed afterwards.
  4. Keep system names generic if they are confidential ("payments platform" is fine).
  5. Run the built-in resume checker and paste the job description into the keyword match before you download.
