Head of Engineering, Daybase
Led engineering across Daybase's full technology footprint, including physical location build-outs (wifi, networking with Myriad, and access control systems) and a contractor team delivering on-site technology operations. Oversaw and shipped the complete product stack: consumer mobile apps, iPad kiosks, back-office employee support apps, APIs, and the web application. Architected and launched the GraphQL API that replaced the MVP Lambda backend, improving real-time data synchronization, reliability, and cross-surface consistency. Established launch playbooks for new sites to reduce setup time and operational risk.
Senior Engineering Manager, WeWork
Built Dealtrack, WeWork's real-estate pipeline platform, by partnering with product and design to connect field evaluators and portfolio decision-makers in one workflow. Shipped a native iOS app for low-connectivity site capture plus a web experience with automated deal summaries, document/API data enrichment, and auditable revision timelines. The system eliminated duplicate site visits and contributed to a 3x increase in annual lease signings with faster proposal and approval cycles.

VP Engineering, Fieldlens (Acquired by WeWork)
Built a consumer-first product experience for construction superintendents: capture observations in seconds on mobile and automatically generate the daily reports that previously took hours. Product strategy centered on immediate individual user value that also created structured enterprise data. Scaled from 300 beta users to 100K+ active users in about three years, surpassed $1M ARR, and helped drive the eventual acquisition by WeWork.
