About Jason

Power Platform Solution Architect, CoE and Copilot Studio, 10 years on the Microsoft stack.

I help companies seriously leverage their Microsoft licensing on Power Platform. My angle: solid architecture, structured governance, and pragmatic integration of Copilot Studio into business processes.

Some recent contexts:
- Full deployment of a Power Platform CoE for a major public operator in Luxembourg (CoE Starter Kit, DLP, environment strategy, Citizen Developer process).
- Architecture of a Power Pages portal serving 300K end-users for an Asian public organization, with Dataverse and Azure B2C for authentication.
- Modernization of an industrial ERP with Power Platform, managing distributed teams in Morocco and Tunisia.
- Copilot Studio pre-sales in agent AI mode for clients in Asia.

I work fully remotely from Vietnam (UTC+7). My schedule largely covers European business hours, and I adapt to client needs: on my last French mission, meetings were in the afternoon Paris time because it suited the team. Flexible hours are part of the contract.

Happy to discuss your Power Platform, CoE, or Copilot challenges.
