How are security practices implemented?

The skill provides guided workflows for implementing the OWASP Top 10 defenses, including JWT configuration, rate limiting middleware, and Zod-based input validation.

Can it generate API documentation?

Yes, the API Scaffolder tool can both generate code from an OpenAPI spec and generate an OpenAPI specification from your existing route handlers.

How does the skill help with database performance?

It includes a database migration tool that analyzes your PostgreSQL connection to identify missing indexes, suggest schema optimizations, and generate safe migration files.

Does it include tools for performance benchmarking?

Absolutely. It features an API Load Tester that measures throughput, success rates, and latency percentiles (P50, P95, P99) under configurable concurrency.

What frameworks are compatible with this backend skill?

This skill specifically supports Node.js environments and provides tailored scaffolding for Express.js, Fastify, and Koa frameworks.

API Development

Accelerates backend development through API scaffolding, database performance optimization, and rigorous security hardening.

The Senior Backend Engineer skill is a comprehensive toolkit designed to streamline the entire backend lifecycle, from initial API design using OpenAPI specs to production-ready performance tuning. It provides specialized workflows for generating route handlers in Express or Fastify, analyzing PostgreSQL schemas for missing indexes, and conducting high-concurrency load tests. By implementing industry-standard patterns for authentication, input validation, and database migrations, this skill enables developers to build scalable, secure, and high-performance Node.js services with minimal manual boilerplate.
