Backend Developer Orchestrator

Coordinates two specialized backend sub-skills for systems-level and enterprise web development.

Purpose

Routes backend tasks to appropriate sub-skill based on language and context.

Context Discovery

Auto-Investigation

Detect backend stack from project:

Signal	How to Check	What It Tells Us
go.mod	Glob("**/go.mod")	Go project → :systems
Cargo.toml	Glob("**/Cargo.toml")	Rust project → :systems
pom.xml	Glob("**/pom.xml")	Java Maven → :enterprise
build.gradle	Glob("**/build.gradle*")	Java Gradle → :enterprise
*.csproj	Glob("**/*.csproj")	C# .NET → :enterprise
composer.json	Glob("**/composer.json")	PHP → :enterprise
Gemfile	Glob("**/Gemfile")	Ruby → :enterprise
DB config	Grep("postgres|mysql|mongodb", "**/*")	Database type

Discovery Questions

Q1: Backend Language (if not detected)

question: "What backend language are you using?"
header: "Language"
multiSelect: false
options:
  - label: "Go"
    description: "High-performance, concurrent services"
  - label: "Rust"
    description: "Memory-safe, systems programming"
  - label: "Java (Spring)"
    description: "Enterprise, Spring Boot"
  - label: "C# (.NET)"
    description: "Microsoft ecosystem"
  - label: "PHP (Laravel)"
    description: "Web applications"
  - label: "Ruby (Rails)"
    description: "Rapid development"

Routing:

• "Go" or "Rust" → Skill(faion-backend-systems)
• "Java", "C#", "PHP", "Ruby" → Skill(faion-backend-enterprise)

Q2: Backend Task Type

question: "What type of backend work?"
header: "Task"
multiSelect: false
options:
  - label: "Build new service/API"
    description: "Create from scratch"
  - label: "Database design/optimization"
    description: "Schema, queries, performance"
  - label: "Add caching/queues"
    description: "Infrastructure patterns"
  - label: "Fix bugs/refactor"
    description: "Improve existing code"

Routing:

• "Database" → database-design, sql-optimization
• "Caching/queues" → caching-strategy, message-queues
• Others → language-specific methodologies

Sub-Skills

Sub-skill	Focus	Methodologies
faion-backend-developer:systems	Go, Rust, databases, caching	22
faion-backend-developer:enterprise	Java, C#, PHP, Ruby frameworks	25

Routing Logic

Route to :systems for:

• Go microservices, concurrency, HTTP handlers
• Rust backend services, async, ownership
• Database design, SQL optimization, NoSQL
• Caching strategies, message queues
• Low-level error handling

Route to :enterprise for:

• Java Spring Boot, JPA, Hibernate
• C# ASP.NET Core, Entity Framework
• PHP Laravel, Eloquent, queues
• Ruby Rails, ActiveRecord, Sidekiq
• Enterprise patterns and testing

Integration

Invoked by parent skill faion-software-developer for backend work. Automatically selects appropriate sub-skill based on task context.
