About this gig
I will be your dedicated Rust developer for high-performance backends, APIs, and systems programming.
I build production-grade, memory-safe, fast Rust and I ship it all the way to live deployment. My work runs in production right now: a live Solana mainnet indexer streaming real-time data, an on-chain escrow platform, and a payments protocol. I'll share the live links in chat.
What I offer:
Rust backend APIs (Axum, Actix-web, Rocket)
Async & concurrent services (Tokio)
CLI tools and automation (Clap)
Database integration (SQLx, Diesel, Postgres)
WebAssembly (WASM) modules
Code review and bug-fixing for existing Rust projects
Why choose me? I write clean, idiomatic, well-tested Rust with proper error handling and performance-first design. Every deliverable is production-ready, not just "it compiles." I've taken real systems from architecture to live deployment, so you get an engineer who ships, not just writes.
Message me before ordering to discuss your requirements and align on scope. I respond fast and keep communication clear throughout.

I'm a backend and blockchain engineer who builds production systems in Rust and on Solana. Smart contracts, APIs, databases, and real-time data pipelines, taken from architecture all the way to live deployment.
My work runs in production: a live Solana mainnet indexer, an on-chain escrow bounty platform, and a payments protocol. I also build backends in Go and TypeScript, picking the right tool for each project.
I care about clean, tested code, clear communication, and realistic timelines. Message me before ordering and let's scope your project properly.

FAQ
Can you work with my existing Rust codebase?
Yes, I can review, refactor, extend, or fix bugs in your existing project. Share the repo when you reach out so I can scope it accurately.
Do you provide documentation with the code?
Yes, every deliverable includes inline doc comments and a README with setup, build, and usage. Larger projects also get architecture notes.
Can you integrate with my database or external APIs?
Absolutely. Postgres, SQLite, and Redis via SQLx and Diesel, plus REST/gRPC integrations. Tell me your stack.
Do you write tests?
Yes. Unit tests come with Standard and Premium; Premium adds integration tests and a CI pipeline (GitHub Actions or similar).
Do you have experience with async Rust?
Yes. I work with Tokio regularly for concurrent servers and high-throughput async services
Can you build a CLI tool in Rust?
Yes, CLI tools are a specialty. I use Clap for anything from simple scripts to full terminal apps with subcommands and config.
Can you help with WebAssembly (WASM)?
Yes. I compile Rust to WASM with wasm-pack and wasm-bindgen and integrate it into a JS/TS frontend for performance-critical browser code.
How do you handle project requirements?
Message me before ordering with what you need. I confirm scope, timeline, and package fit before you order, so there are no surprises.
Do you work on blockchain / Solana projects?
Yes. Much of my production Rust is on Solana — smart contracts in Anchor and a live mainnet indexer. I can link you working examples.
