Enterprise Salesforce,
led end-to-end.

I own the program: scope, executives, delivery, go-live, and the rescue when it stalls. Salesforce client delivery, programme leadership, and training — the receipts are on this page.

WHAT I DOPROOF, NOT PACKS
  • Salesforce client delivery

    I lead complex programs from scope through go-live, and recover them when they stall.

  • Programme and project management

    Governance, vendors, risk, decision rights, and an accountable handoff the client can own.

  • Training and capability

    I build delivery capability in client and partner teams — the same work that scaled a practice from 5 to 200.

No slides. No pitch. Bring the decision context and current artifacts.

"His insights are always spot-on and incredibly valuable. He is a tremendous asset to any team."

JUNO NOH, SENIOR IT MANAGER, L'OCCITANE KOREA

THE STALL

A program stalls when nobody owns the decision.

Vendors keep moving. Scope keeps growing. The pack looks current. The handoff does not exist.

Named programs, named outcomes

Evidence before assertion

Enablement, not a course catalogue

ONE PRACTICE

You bring the decision context.

The two surfaces lock. Same Salesforce practice.
