READY-TO-USE TEMPLATES

Production-ready templates and guides for building LLM applications with design patterns. These templates are optimized for Claude Code integration and rapid enterprise development.

🚀 Essential Decision Guide

🎯 LLM Pattern Decision Guide

The most important resource for LLM system development.

What it provides:

• Instant Pattern Selection: Decision matrix based on your specific requirements

• Production-Ready Templates: Code from real enterprise systems (LiteLLM, FastMCP, ByteDance)

• ROI Insights: Expected cost savings and implementation time

• Anti-Pattern Warnings: Common mistakes and proven solutions

Quick Examples:

• Need multi-provider AI? → Adapter + Strategy (60-80% cost reduction)

• Building AI tools? → Decorator + Registry (80-90% dev time savings)

• Enterprise gateway? → Proxy + Observer (Full production control)

💡 Perfect for: Claude Code pattern selection, rapid prototyping, enterprise deployments
