🚀 High-Performance Backend Skill

A Claude Code skill for building production-grade, high-performance backend services in Java, Rust, and Go.

Includes a 40-scenario tech stack decision matrix that maps real-world business scenarios to battle-tested technology combinations — so you get architecture recommendations, not just code snippets.

✨ Features

Interactive Tech Stack Advisor

Instead of jumping straight to code, this skill first asks about your business scenario, scale requirements, and constraints, then searches a curated decision matrix to recommend the right technology combination.

40+ Real-World Scenario Templates

Each template is a complete architecture blueprint covering:

Dimension	What's Included
Language & Framework	Java/Spring Boot 3, Rust/Axum, Go/Gin, and more
Communication	REST, gRPC, WebSocket, MQTT, Kafka, NATS
Databases	PostgreSQL, Redis, ClickHouse, TimescaleDB, Neo4j, etc.
Caching	L1 in-process + L2 distributed strategies
Architecture	Hexagonal, CQRS, Event Sourcing, Saga, Pipeline
Resilience	Circuit Breaker, Bulkhead, Backpressure, Retry
Observability	OpenTelemetry, Prometheus, Grafana
Deployment	Kubernetes, Edge, Bare-metal

Business Domains Covered

• 🛒 E-commerce — Product catalog, orders, payments, flash sales, recommendations, user accounts
• 💬 Social — Feed/timeline, instant messaging, user relationships
• 💰 Fintech — Market data, matching engine, risk control, clearing & settlement
• ☁️ SaaS — Multi-tenant API, billing & metering
• 📡 IoT — Device gateway, data pipeline, edge computing
• 🎮 Gaming — Lobby/matchmaking, battle server
• 🤖 AI/ML — Model serving gateway, feature engineering
• ⛓️ Blockchain — Node RPC gateway, on-chain indexer
• 🏢 Enterprise — Workflow engine, file storage, auth center
• 📊 Monitoring — Metrics collection, log aggregation
• 🔔 Notification — Multi-channel push service
• 🔍 Search — Full-text search platform
• 📋 Compliance — Audit logging

Deep-Dive Reference Guides

Once the skill recommends a stack, it loads language-specific reference guides with production-ready patterns:

• Java/Spring Boot 3 — Virtual Threads, Resilience4j, Spring Cloud, JPA optimization, GraalVM Native Image
• Rust — Axum patterns, Tokio runtime tuning, SQLx, moka cache, release profile optimization
• Go — Gin/stdlib, pgx connection pool, errgroup, singleflight, pprof profiling

📦 Installation

Option A: As a Plugin (Claude Code CLI)

# Add as marketplace
/plugin marketplace add GChenSi-2/high-perf-backend-skill

# Install the skill
/plugin install high-perf-backend@silicon-backend-skills

Option B: Manual Install (Claude Code CLI)

# Clone and copy to your skills directory
git clone https://github.com/GChenSi-2/high-perf-backend-skill.git
cp -r high-perf-backend-skill/skills/high-perf-backend ~/.claude/skills/

Option C: Upload to Claude.ai

1. Download the high-perf-backend.skill file from Releases
2. Go to Settings → Customize → Skills
3. Click "+" and upload the .skill file

🎯 Usage

Just describe what you're building:

"I need to build a real-time market data feed service that handles 100K+ concurrent WebSocket connections with sub-10ms latency"

The skill will:

1. Ask clarifying questions about your constraints
2. Search the decision matrix for matching scenarios
3. Present a structured recommendation with trade-offs
4. Offer to generate production-ready scaffolding code

Or go straight to coding:

"Help me set up an Axum REST API with SQLx and PostgreSQL"
