Before

In 2018, Honeywell spun off its home division to create Resideo, inheriting 50+ offices and over 100 fragmented smart home products spread across water, energy, air, and security.

  • 27+ legacy apps across acquisitions and verticals

  • Pro and consumer systems couldn’t communicate

  • Thermostats, security, and energy tools operated in silos

  • Outdated firmware, technician-locked devices, and ecosystem gaps led to customer frustration

What I did

I joined the new consumer product team to design a unified app in just 3 months, consolidating 27+ legacy apps and integrating new acquisitions. My core contributions:

  • System Architecture: Designed a layered dashboard model for whole-home visibility

  • Widget Framework: Created modular controls for cross-device functionality

  • Notification System: Defined 5-tier alert model for nuanced, action-oriented messaging (especially for security events)

  • Water & Energy Systems: Led design of adaptive scheduling, cloud-enabled control, and gamified model training (e.g., swipe-to-teach water usage categorization)

  • Cross-System Integration: Proposed behavior-based automations (e.g., turning off water if pipes might burst & security confirms no one is home)

Impact

What I Learned

  • Merging pro and consumer perspectives revealed edge cases early

  • Speed doesn’t kill design; misalignment does. Tight deadlines succeeded through extreme clarity and decisive leadership

  • Training models with human support creates smarter, more trustworthy systems
