Prebuilt Projects2Jobs roadmap
Backend Developer Roadmap
Demonstrate API design, data modeling, background jobs, observability, and production reliability.
Backend and full stack candidates who need stronger systems depth.
Timeline
9 weeks
Level
Intermediate
Final outcome
A production-style backend portfolio with auth, relational data, background jobs, metrics, and reliability notes.
Skills to prove
REST APIs
Postgres
Auth
Queues
Caching
Observability
Portfolio projects
- Multi-tenant API with auth, rate limits, and audit logs
- Job queue service with retries, dead-letter handling, and metrics
- Database-heavy app with migrations, indexes, and query performance notes
Prebuilt build path
Follow these phases in order. Each one ends with a portfolio artifact you can show in GitHub, on your resume, or in interviews.
Step 1
Weeks 1-3
Design the API and data model
Show clear boundaries, permissions, schema choices, and API contracts.
- Model organizations, users, roles, permissions, and audit events in Postgres.
- Build REST endpoints with validation, pagination, filtering, and consistent error responses.
Deliverable: A documented API with schema diagrams, seeded data, and endpoint examples.
Step 2
Weeks 4-6
Add reliability and background work
Prove you understand async work and failure handling.
- Create background jobs with retries, idempotency keys, and dead-letter handling.
- Add caching for expensive reads and explain the invalidation strategy.
Deliverable: A job-backed backend service with clear retry and failure behavior.
Step 3
Weeks 7-9
Instrument and explain the system
Make the project interview-ready with operational evidence.
- Add structured logs, health checks, basic metrics, and query performance notes.
- Write a README section covering tradeoffs, bottlenecks, and future scaling steps.
Deliverable: A deployable backend case study with metrics, tests, and architecture notes.
