I will fix your rust build, compiler, lifetime, and concurrency errors

Stuck on a Rust borrow checker error, lifetime mismatch, or async Tokio deadlock?

I am a Senior Systems & Web3 Engineer with 7+ years of deep Rust experience building distributed protocols, consensus layers, and high-throughput systems. I will resolve your compiler or runtime bugs and provide clean, idiomatic code with zero regressions.

What I solve:

- Borrow checker and lifetime conflicts (Arc<Mutex<T>>, Send + Sync)

- Tokio / async runtime panics and deadlocks

- FFI, C++ bindings, and unsafe blocks

- Cargo build failures and cross-compilation errors

Deliverables:

1. Clean, tested, compiling patch or pull request.

2. Clear explanation of the root cause and prevention steps.
