Available to hire
Hi, I’m Nathan Timmis, a seasoned engineer with over 10 years of experience specializing in blockchain infrastructure, AI systems, and full-stack protocol engineering. I focus on building secure, high-performance, and modular systems that sit at the crossroads of Web3 and large-scale machine learning. My passion lies in deploying transformer-native backends and zero-knowledge smart contract frameworks to empower DeFi, staking, and secure identity layers.
I thrive in dynamic, agile, and remote-first environments where privacy, self-sovereignty, and edge inference are prioritized. My work is centered on crafting next-generation crypto-native applications by blending zero-knowledge infrastructure with intelligent ML agents, delivering resilient production-grade solutions across multiple blockchain and cloud ecosystems.
