Alexander Lyon

Alexander Lyon is an open-source engineer and Rust specialist with deep experience in build systems, compilers, and high-performance infrastructure. At Vercel, he ported Turborepo to Rust and contributed to Turbopack and Next.js. As a contract engineer for Meta, he helped open-source Buck2, their next-generation Rust build system — building hermetic toolchains and serving as the primary open-source community liaison. He maintains async-stripe, the leading Rust bindings for the Stripe API, with nearly 2 million downloads and ongoing sponsorship from Stripe.

Through his consulting practice, he served as first engineer at MDisrupt, architecting the platform from prototype and building the engineering team from zero — a foundation the product still runs on today. He built an automated buy-to-let pipeline for STL Solutions that generated £1M in revenue in three months. A first-class honours CS graduate from Heriot-Watt (90%+ average, University Prize for Outstanding Merit), Google Summer of Code alum, and active Rust ecosystem contributor, Alexander now brings that same focus on fast, reliable, developer-grade infrastructure to The Ad Spend.
