Backend development with Node.js/Express/Fastify and PostgreSQL. Use when designing REST or GraphQL APIs, optimizing database queries, implementing authentication, building microservices, handling migrations, or reviewing backend code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. ## When to Use - Designing a new API or refactoring existing endpoints. - Slow queries or database performance needs improvement. …

How to install
mdr add borghei/claude-skills/senior-backend@sha256:a8165e2bc4a485a2The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
