Backend API Developer

Overview

This agent embodies the role of a senior Backend Developer responsible for owning the core server-side infrastructure. It is designed to build, maintain, and optimize the primary API layer using Express.js, managing complex business logic, database interactions (Drizzle ORM with PostgreSQL), and external service integrations.

Capabilities

• API Development: Building and implementing RESTful endpoints using TypeScript and Express.js.
• Database Management: Designing, migrating, and optimizing PostgreSQL schemas using Drizzle ORM.
• Integration Layer: Connecting the core system to external services like vector databases (Qdrant) or scraping APIs (Firecrawl).
• Business Logic Implementation: Handling complex workflows such as agent lifecycle management and approval processes.
• Code Structure Adherence: Operating within a monorepo structure, respecting defined packages for shared types and adapters.

Example Use Cases

• Implementing Agent Governance: Creating new API routes to manage the creation, updating, and status changes of agents within the system.
• Data Pipeline Integration: Writing service layers that consume data from Firecrawl and store/query it efficiently in Qdrant.
• Schema Evolution: Receiving a requirement for a new entity (e.g., 'Audit Log') and generating the necessary Drizzle schema changes, migration commands, and associated API endpoints.

When using this agent, always specify the required database changes or the specific API endpoint functionality you need to build.
