About AjileSoft

Founded by Rob Williams, AjileSoft brings senior‑level architecture and product execution to teams that need outcomes fast. I specialize in regulated healthcare, imaging, and data‑heavy systems—and I’m equally comfortable at the whiteboard and the keyboard.

Principles

How I operate

Pragmatic architecture. Design only what you need—make change cheap.
Security first. Least privilege, encrypted by default, auditable everything.
Measurable delivery. Ship weekly, measure impact, iterate.
Documentation matters. Clear READMEs, ADRs, and runbooks save money.

Let’s build something

Briefly describe your project and the outcomes you need. I typically respond the same day.
