Backend Developer

You're a backend developer. Here's your toolkit.

You build APIs, design database schemas, wire up background jobs, and keep services fast under load. OrchestKit gives you 7 skills covering FastAPI, SQLAlchemy, Celery, caching, and connection management -- plus 3 agents that can design endpoints, write migrations, and architect event-driven systems alongside you. Instead of switching between docs tabs, you describe what you need and the right patterns are injected automatically.

Your Skills

Skill	What it does
`fastapi-advanced`	Lifespan events, dependency injection, middleware chains, and Pydantic settings for async Python services
`database-schema-designer`	SQL and NoSQL schema design with normalization, indexing strategies, and migration planning
`alembic-migrations`	Alembic migration patterns for SQLAlchemy 2.0 async -- reversible changes, zero-downtime deploys
`celery-advanced`	Canvas workflows, priority queues, rate limiting, multi-queue routing, and Flower monitoring
`sqlalchemy-2-async`	AsyncSession, async_sessionmaker, and FastAPI integration for async ORM queries
`connection-pooling`	asyncpg and aiohttp pool configuration, connection lifecycle tuning for high-concurrency services
`caching-strategies`	Redis write-through, write-behind, cache-aside, TTL management, and stampede prevention

Your Agents

Agent	Model	Activates when...
`backend-system-architect`	opus	API design, database schema, microservice, REST, GraphQL, JWT, middleware, dependency injection
`database-engineer`	inherit	database, schema, migration, PostgreSQL, pgvector, SQL, Alembic, index, constraint
`event-driven-architect`	opus	event sourcing, message queue, Kafka, RabbitMQ, pub/sub, CQRS, saga, outbox pattern

Your Workflows

Implement a Feature -- Describe a feature, get parallel agents writing endpoints, tests, and security scans simultaneously
Run a Security Audit -- 8-layer defense-in-depth scan that checks auth, input validation, and data handling across your backend

Quick Start

Try this right now:

/ork:implement "Add cursor-based pagination to the /api/users endpoint"

The backend-system-architect agent picks up the task, pulls in api-design-framework and fastapi-advanced skills, and produces the endpoint with proper cursor encoding, Pydantic response models, and integration tests.
