I lead observability and SRE for American Express travel platform production support at iSeatz — the middleware integrating car, hotel, and air suppliers. I build OpenTelemetry-based observability stacks and use AI to do preemptive root cause analysis — pulling production telemetry, cross-referencing it against code, and fixing issues before they become incidents.
15+ years across SRE, platform engineering, and cloud architecture. Previously Director of Platform Engineering at Trajector, Principal Technical BDM at AWS, and Senior Manager at Salesforce. Enterprise clients include American Express, Johnson & Johnson, CVS, and Mastercard. Ph.D. from the University of Florida.

Figma Is a Persuasion Tool. I'm Not Persuading Anyone.
Wireframes are too concrete, words are too abstract. Ryan Singer figured this out years ago. Breadboard notation — places, actions, connections — turns out to be the perfect fidelity for communicating with an AI coding session.
