Backend Developer CV Example
APIs, data models and queues under real load — backend work measured in throughput and reliability.
Backend work is invisible until it fails, so a backend CV must make the invisible measurable: requests served, queues drained, incidents avoided. This example quantifies load on every major system and shows the data-modelling judgement that ads rarely test but teams badly need.
Why this CV works
- Load numbers (req/s, p99) frame every system, so scale is never left to the reader's imagination.
- The schema-redesign bullet shows the rarest backend skill — fixing the data model, not just the code around it.
- Money reconciled with "zero unexplained differences" is the strongest reliability sentence a backend CV can carry.
- Tested restores and deprecation policy show operational adulthood beyond feature work.
The professional summary
Backend Developer with 6 years building APIs and data pipelines in Node.js and PostgreSQL for marketplace platforms. Runs an order API serving 900 req/s at p99 under 200ms, redesigned the schema that removed the platform's worst lock contention, and built the settlement pipeline reconciling AED 40M monthly with zero unexplained differences.
State your primary language, database and the load your biggest system carries. Backend hiring starts with "can they handle our scale" — answer it in line one.
Writing the work experience
Give each system its load figure and each fix its before/after. Contention removed, queries accelerated and pipelines reconciled are the three classic backend stories — tell yours with numbers.

ATS tips for Backend Developers
- Write "back-end", "backend" and "back end" once each — filters are literal about the hyphen.
- Name the exact database and queue (PostgreSQL, RabbitMQ); "SQL databases" and "message queues" under-match.
- "API design" and "REST API" both belong — ads use both phrasings.
ATS checks help identify potential compatibility issues, but employers and ATS platforms use different criteria — no template or score can guarantee an outcome.
Writing tips
- p99 beats average latency in every claim — it shows you know which number matters.
- A prevented failure ("stalls now zero") is worth as much as a built feature; count what stopped happening.
- Restore drills, deprecation policies and monitoring are unglamorous — and precisely what senior reviewers scan for.
Frequently asked questions
How do I show impact when my work has no UI?
Through load, latency, reliability and money: requests served, differences reconciled, incidents prevented. Backend impact is numeric by nature.
Is database work worth its own bullets?
Yes — schema and query bullets often outweigh feature bullets, because data-model judgement is scarce.
Do certifications matter for backend roles?
Marginally. One relevant certification is a tiebreaker; production numbers are the decision.
