About me

I'm a SharePoint specialist, Microsoft 365 consultant, and full-stack developer focused on delivering secure, scalable solutions that create measurable business value. With a strong foundation in systems science and hands-on experience across enterprise environments, I design and implement modern applications spanning SPFx, Power Platform, React, Next.js, Node.js, and TypeScript—bridging business needs and technical execution from architecture through delivery.

At Sogeti and now CGI, I've had the privilege of working alongside talented teams on complex architectural challenges. Those collaborations shaped how I approach problems and significantly deepened my technical judgment. I thrive when learning from others and delivering solutions that actually move the needle.
