I will be your rust developer for backend API, cli tool, webassembly and systems


Level 2
À propos de ce service
If you need Rust done right not just working, but fast, clean, and built to last you're in the right place. I'm a Rust engineer who writes production-grade systems for a living, including Solana blockchain programs where a memory bug isn't a minor issue, it's a drained wallet. That standard of correctness carries into every project I take, whether it's a backend API, a CLI tool, a WebAssembly module, or a Python rewrite that needs to run 50x faster.
What I build:
- Backend APIs Axum or Actix-Web on Tokio, PostgreSQL via SQLx, Docker-ready
- CLI tools Clap-powered, cross-platform binaries with zero dependencies
- WebAssembly wasm-pack compiled, TypeScript bindings, npm-publishable
- Python or Node.js rewrites benchmark report showing real speedup included
- Solana programs smart contracts, DeFi, on-chain integrations via Anchor
Why clients come back:
- Clean, documented, maintainable code not just code that compiles
- Honest scoping I tell you what's realistic before you order
- On-time delivery with transparent communication throughout
Not sure which package fits your project? Message me and I'll scope it for free.

FAQ
What info do you need to get started?
Project goals, requirements, reference examples and any existing code or API details.
Can you rewrite my Python script in Rust?
Yes. Share your script, describe what it does and what your performance target is, and I'll give you an honest estimate of the speedup you can expect and an accurate timeline before you order. I don't promise 100x if 10x is realistic you'll get real numbers.
How does the WebAssembly integration work for my frontend?
I write your logic in Rust, compile it to .wasm with wasm-pack, generate JavaScript/TypeScript bindings with wasm-bindgen, and bundle everything as an npm package. On your end, it's just `import { yourFunction } from 'your-package'` it looks and feels like any other npm module.
Do I need to know Rust to use what you deliver?
Not at all. CLI tools arrive as standalone binaries just run them. Wasm modules arrive as npm packages just import them. APIs arrive as Docker containers just deploy them. You interact with the interface, not the implementation.
Can you add a GUI to the CLI tool?
I can add a TUI (terminal user interface) using Ratatui, which gives you interactive menus, tables, and input forms inside the terminal itself. For a full graphical desktop application, I use Tauri which wraps your Rust backend in a web-based UI fast, lightweight, and cross-platform.
How does Rust compare to Go for backend APIs?
Both are excellent. Rust is faster and uses less memory, and is the better choice if performance is critical or if the system handles sensitive data where memory safety matters. Go compiles faster and has simpler concurrency primitives, making it better for teams that need to onboard quickly.
