Current role

Director of Engineering at Cisco (Duo Security)

Leading engineering teams across Duo SSO and mobile app surfaces, focused on identity, security, reliability, delivery, and team health.

Leadership focus

Healthy teams and reliable delivery

Building pragmatic engineering systems that improve product quality, execution, and cross-functional clarity.

Working style

Calm, practical, product-minded

Turning ambiguous goals into clear decisions, durable plans, and healthier day-to-day engineering habits.

AI in Practice

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

Code

Prototype and explore

Use Codex, Copilot, Cursor, and Claude Code to prototype, debug, refactor, and understand unfamiliar code.

Planning

Clarify fuzzy ideas

Turn vague goals into options, risks, tasks, design choices, and next-step plans.

Review

Prepare better reviews

Surface edge cases, test ideas, and clear diff summaries before decisions get rushed.

Docs

Reduce explanation toil

Draft and improve technical docs, onboarding notes, and explanations for teams.

Selected Work

Public-safe themes from work that can be discussed responsibly. Full case studies can come later when the scope is shareable.

Identity and security

Identity & Security Engineering Leadership

Engineering leadership across Duo SSO and mobile app surfaces at Cisco (Duo Security), with focus on reliable identity experiences, delivery, product quality, and healthy teams.

Mobile product leadership

Expedia Mobile Product Leadership

Managed mobile app engagement and Ann Arbor engineering teams across Expedia’s mobile portfolio, partnering across product, design, and platform teams to improve quality, delivery, and customer experience.

Practical AI adoption

AI Adoption for Engineering Teams

Helping teams use AI for planning, prototyping, code exploration, review prep, documentation, and reducing toil while keeping engineering judgment central.

Operating systems
