From websites to autonomous systems.

The scope has expanded since 2008, but the throughline has stayed the same: understand the operation, make it legible, and build the right system.

SUMMARY

I have built software since 2008 across product design, web and mobile applications, APIs, data systems, cloud infrastructure, enterprise automation, and reliable AI systems. I work best where the problem crosses boundaries and someone needs to own the whole path from ambiguity to dependable operation.
