Senior Blockchain & Backend Engineer Self-Employed
I build production Solana and DeFi trading infrastructure using asynchronous Rust and Go. My work includes a low-latency multi-venue arbitrage engine, Drift Protocol automation, and Rust/Anchor on-chain programs.
I implemented Yellowstone gRPC streaming, self-hosted Jupiter routing, Jito bundle submission, and transaction simulation for reliable automated trading. I integrated more than 30 Solana venues across CLMM, CPMM, DLMM, DAMM, and order-book models, including Raydium, Meteora, Orca Whirlpool, Phoenix, and PumpSwap.
I also develop SaaS APIs and microservices with Tokio, Axum, Actix Web, and Gin. I created Rust-Python integrations using PyO3, developed a Tauri V2 application, and established observability, metrics, alerting, Docker-based delivery, and GitHub Actions CI/CD workflows.
