🚀 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

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

# 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

- 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:
- Ask clarifying questions about your constraints
- Search the decision matrix for matching scenarios
- Present a structured recommendation with trade-offs
- Offer to generate production-ready scaffolding code
Or go straight to coding:
"Help me set up an Axum REST API with SQLx and PostgreSQL"
