Cloud Migration

A $42M move off mainframe onto Oracle ERP in AWS, with isolated environments and controlled promotion between them.

Left to right is time. Each row is one of the 7 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Set architecture direction for the migration of the City of Jacksonville’s financial systems off mainframe onto Oracle ERP hosted in AWS — a $42M program — with isolated development, QA and production environments, controlled promotion between them, and the data-handling boundaries that separation requires.

Also directed the migration of the Office of General Counsel into Microsoft Azure, owning tenancy, placement and the segmentation tying cloud workloads back to the enterprise.

  • Commercial Site Rebuild and Live Domain MigrationApril–September 2026Twenty pages moved off a hosted page builder onto a static build, and a live domain repointed to a new host without touching any of the six records carrying its mail.
  • Oracle ERP Program — RFP to Cloud Go-Live2011–2023Twelve years from the 2011 request for proposal to a 2020 cloud go-live — the cost model that had to exist first, and a cutover instrumented so neither side could blame the other.
