Common mistakes on resumes for this role
- Framework named with no scale context — "built REST APIs with Express" says nothing about traffic, data volume or uptime handled.
- No system design vocabulary. Load balancing, caching, queueing and horizontal scaling are absent even under senior-sounding titles.
- Database bullets read as CRUD ("created endpoints to read and write data") instead of schema decisions, indexing or migration work.
- Security skipped entirely — auth, rate limiting, input validation rarely appear even though nearly every backend posting asks for them.
