What to Expect
Backend roles are language-agnostic and broad in scope. A single work session might include a Python FastAPI endpoint, a Node.js Express middleware chain, and a PostgreSQL query plan to review. You'll evaluate API design decisions (REST vs. GraphQL, pagination strategies, versioning approaches), database schema choices (normalization, index selection, query optimization), caching strategies (Redis, in-memory, CDN), and message queue implementations (Kafka, RabbitMQ, SQS). Tasks are independent and self-contained, so you can work in your strongest language each session. Infrastructure tasks (Dockerfile quality, Kubernetes manifests, Terraform configurations) appear in this category too.

Frequently Asked Questions
What backend languages do I need to know?
Common: Node.js, Python (Django/FastAPI), Java, or Go. You don't need to know all—platforms let you filter by language. However, knowing multiple increases opportunity volume.
What is database design evaluation?
You'll assess schema normalization, indexing strategy, query optimization, and scalability. Tasks include spotting N+1 problems, evaluating ACID compliance, and reviewing NoSQL vs relational trade-offs.
How much backend experience do I need?
Typically 2+ years professional backend development. You need to understand API design, databases, caching, message queues, and distributed systems concepts. Bootcamp grads with 2+ years experience may qualify.
Do I need DevOps/infrastructure knowledge?
Helpful but not always required. Some roles evaluate Docker/Kubernetes, but most focus on code logic. DevOps skills unlock additional tasks and may increase rates by 10-20%.
