Meet Some of Our Architects

Michael Deslongchamps

Michael Deslongchamps

Custom Delivery Director

“Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn't really do it, they just saw something. It seemed obvious to them after a while. That's because they were able to connect experiences they've had and synthesize new things.”
Steve Jobs

Michael leads the Custom Development team with over 15 years' experience developing custom software applications. He works with clients translating business requirements to technical architecture plans and ensures successful implementation of these plans.

Michael spends time outside of work creating games using the Unity and Unreal game engines. He is head instructor of a local martial arts outreach ministry, and enjoys playing Dungeons and Dragons with his 3 children and annoying his wife with witty banter.
