Ace Chalhoub

Software engineer, engineering leader, and founder.

I'm currently VP of Engineering and Head of AI Innovation at Bottomline. Before that, I co-founded TreasuryXpress, where I was CTO and Managing Partner through its acquisition.

Most of my career has been spent building treasury and payment software, scaling engineering teams, and working on architecture, cloud infrastructure, and product delivery. More recently, I've been focused on turning AI prototypes into production products.
