Eric Cain
Software Developer
Building robust systems from the ground up — Linux, systems programming, and cloud infrastructure.
About
I'm a software developer with over 20 years of experience in Linux and systems programming. I specialize in low-level languages and building robust, efficient software—from cloud infrastructure (AWS) to systems-level code.
I've spent two decades working close to the hardware—network protocols, device drivers, and cloud infrastructure—and enjoy tackling problems that need both technical depth and clear design.
I focus on software that is performant, maintainable, and well-architected, from systems-level code to deployment pipelines.
