Our Team

I work closely with multiple business-aligned engineering teams to provide best-in-class monitoring, alerting, and platform tooling. Every day, my engineering and investment team colleagues rely on SRE systems to ensure smooth functioning of their platforms. I’m constantly challenged to design resilient, scalable, and reusable solutions, and I’m inspired by how Citadel provides opportunities to learn from my peers, fully own what I build, and help drive commercial outcomes.
