01 — About
Full biography
A cloud architect who ships, leads, and writes.
I help organizations navigate their cloud journey — from first architecture diagrams through production rollout and day‑2 optimization.
My work sits at the intersection of cloud architecture, enterprise integration, and technical leadership. I design systems that stay maintainable, integrate cleanly with what you already run, and give your team a clear path to ownership.
For companies that need senior technical guidance without a full-time hire, I serve as fractional CTO — setting direction, reviewing architecture, hiring engineers, and keeping delivery honest.
