30+ years
architecture and technical leadership
Long-range experience across multiple delivery eras, from earlier enterprise estates to modern cloud-native programs.
Multi-sector
finance to digital product
Work spans financial services, energy, commerce, public-sector environments, and large consumer platforms.
Hands-on
strategy plus execution
Comfortable moving between roadmaps, governance, architecture documentation, delivery alignment, and targeted technical spikes.
Cross-functional
boardroom to delivery teams
Trusted where product, engineering, security, and leadership need a shared frame for technical decisions.
Working context
Set up for consulting across France and Europe.
Based in France. Works comfortably across hybrid and remote collaboration. The best fit is usually senior architecture or advisory work tied directly to delivery rather than abstract strategy detached from execution.
France: permanent or contract roles, hybrid or remote.
Europe: contract roles, remote.
Useful in rooms that mix stakeholders, architects, engineers, and delivery leads.
A fuller detailed CV can be shared directly when procurement or due diligence needs it.
