Jules May

Jules May is a software architect, consultant, and project leader known for designing systems that simply don’t fail. His work spans from safety-critical aviation and automotive software to enterprise cloud platforms, from DSLs and compiler design to algorithmic toolchains.

Starting his career in flight-control systems, Jules learned early that reliability isn’t a feature — it’s a necessity. That ethos has shaped a career focused on clarity, precision, and delivering technology that genuinely works.

He’s the author of Extreme Reliability: Programming Like Your Life Depends on It and the originator of Problem Space Analysis, a practical framework for understanding and solving complex technical problems.

Over the years, Jules has led engineering teams, advised global clients, and spoken at conferences across Europe on reliability, development culture, non-traditional computing and post-quantum security. He’s worked with organisations from start-ups to household names, building solutions that range from embedded systems to high-availability SaaS platforms.

A mathematician by training, a programmer by instinct, and a teacher by inclination, Jules brings a rare combination of theoretical depth and hands-on experience. Whether mentoring developers or shaping strategy as a fractional CTO, he focuses on one thing above all: making software that does what it’s meant to – every time.
