How-To: Show You Meet Backend Requirements in 5 Steps
You don’t need to rewrite your resume for every role. Keep one accurate resume that reflects what you’ve actually done, and use these steps to prepare for the conversations that follow.
- Know your main backend languages. Python plus Java, Go or Node.js covers most roles.
- Describe one API you designed. Consumers, versioning and trade-offs.
- Name your databases. PostgreSQL experience is in high demand.
- Show cloud experience. AWS first, GCP second.
- Add one distributed systems story. Queues, consistency or scale.
