About

I run LeWinter Advisory as a deliberately small practice. One principal, real engagements, no account layer.

Clients hire me because the room needs a senior voice that has actually built, broken, and shipped the thing being discussed. I spend my week inside assessments, architecture reviews, compliance programs, and fractional CTO engagements.

Background. CISSP. Former Cisco. Former Fiserv lead architect on a banking data warehouse product. Experience spanning Financial Services, Hospitality, Manufacturing, and Retail. Deep AWS and Azure. CMMC Registered Practitioner. Based in Nipomo, California.

How I work. Fixed-fee engagements. Structured SOWs. Written, actionable opinions, not hedged recommendations. I stay engaged through the technical work so my clients can get back to running their business.
