About

Director of Engineering at Cisco (Duo Security), leading engineering teams across SSO and mobile products. Focused on healthy teams, pragmatic delivery, reliability, and product quality across security, identity, and mobile experiences.

AI in Practice

AI is used as a practical engineering tool for planning, prototyping, code exploration, code review prep, documentation, and reducing toil. The goal is better engineering judgment, not replacing engineering judgment.

  • Prototype, debug, refactor, and explore code with tools like Codex, Copilot, Cursor, and Claude Code.
  • Turn vague ideas into plans, tradeoffs, risks, tasks, and design options.
  • Prepare code reviews with edge cases, test ideas, and clear diff summaries.
  • Draft and improve technical docs, onboarding notes, and explanations.
Projects

Public project writeups will stay limited to work that can be discussed clearly and responsibly. Current candidates:

  • Expedia mobile product leadership. Management and leadership over mobile travel app work, including FlightTrack 5, with collaboration across product, design, and platform teams.
  • Practical AI adoption for engineering teams. Patterns for using AI in planning, prototyping, code review prep, documentation, and reducing toil while preserving engineering judgment.
