Project description:
"I’m looking for an experienced systems or backend developer to build a high-performance username availability checker with instant claim support for Marvel Rivals.

This project is focused on network performance, timing accuracy, and reliability. There is no UI requirement — the priority is efficient request handling and clean, maintainable code.

Technical Requirements
• Rust or Go (strong preference)
• Highly optimized HTTP networking
• Asynchronous / concurrent request handling
• Precise timing control
• Robust retry & error handling
• Proxy support (HTTP / SOCKS)
• Clear logging and status output
• Config-based setup (targets, timing, proxies)

Nice to Have
• Experience with high-throughput or low-latency systems
• Prior work on availability monitoring or real-time claim systems
• Familiarity with rate limits and backoff strategies
• Strong understanding of async runtimes (Tokio / async-std / Go routines)

Deliverables
• Complete source code
• Configuration files
• Setup & run instructions
• Clean project structure" (client-provided description)
