Software Engineer
I’m a software engineer with 5+ years of experience building high-performance systems for crypto, trading, and blockchain infrastructure. My work spans low-latency trading platforms, market-making systems, on-chain data pipelines, MEV infrastructure, and decentralized compute, primarily using Rust, with additional experience in Go, C++, and Python. I’ve worked on systems supporting EVM, Solana, Aptos, and other blockchain ecosystems, developing everything from execution engines and strategy frameworks to backend infrastructure and developer tooling.
I’m looking for remote software engineering opportunities where I can work on challenging backend, distributed systems, trading infrastructure, or blockchain products. I enjoy working in small, high-impact teams that value ownership, performance, and engineering excellence, especially in startups building developer infrastructure, financial systems, or crypto protocols.
