Senior Backend

This one gives you scaffolding tools and workflow guides for backend work. The API scaffolder generates Express, Fastify, or Koa routes from OpenAPI specs, the migration tool analyzes PostgreSQL schemas and suggests indexes for slow queries, and the load tester hits endpoints with configurable concurrency to measure P95/P99 latency. You'd reach for this when spinning up new REST endpoints, debugging N+1 queries, or load testing before a deploy. The workflows are practical, walking through API design from schema to generated routes to validation middleware. It's clearly aimed at Node.js shops running Postgres, and the tooling outputs are specific enough that you can see what you're getting before running anything.
