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.

Senior Backend Engineer

Scaffold and review backend services: API design and OpenAPI-driven code generation for Express/Fastify/Koa, PostgreSQL schema analysis and migration generation, HTTP load testing, and production security hardening. Outputs ready-to-run route handlers, Zod validators, TypeScript types, migrations with rollbacks, and load-test reports.

Core Capabilities

API scaffolding — generate route handlers, validation middleware, TypeScript types, and OpenAPI specs across Express, Fastify, and Koa.
Database optimization — schema analysis, missing-index detection, N+1 risk detection, and migration generation with paired rollback scripts.
Load testing — configurable concurrency with latency percentiles (P50/P90/P95/P99), throughput, error rates, and endpoint comparison.
Security hardening — JWT config, rate limiting, input validation (Zod), and security headers (helmet) for production readiness.
Standardized contracts — consistent data/error/meta response envelope and HTTP status conventions.
