→ Selected Work
Halo
Working prototype · designed and built · Oct 2026 – present

MarketAxess × X-Pro & Pragma AI
Senior UX Designer · Jun 2022 – Nov 2023
Led the trust layer for Pragma AI, an execution engine handling $2T+ in order flow, and redesigned X-Pro’s pre-trade decision surface with BlackRock, State Street and DWS. ~20% lift in trader volume.

→ What I Bring
Systems first
I map how the system really works, who it serves and where it fails, before I draw a screen. The design follows the model, so the decisions hold up in front of engineers, quants and regulators.
Trust under pressure
Most of my work runs where mistakes cost money: live markets, bank accounts, adversarial networks. I design for the failure case as well as the happy path, and make the hidden judgements visible.
Built, not just drawn
I prototype in code when it moves the decision faster. Halo is a working prototype, not a deck. Teams get something they can test, argue with and ship.
