👋 Hello! I’m an engineering manager (of both humans and AI agents!) focused on developer experience and developer productivity engineering. I’m currently focused on building agentic AI into internal developer platforms, enabling engineering teams to move faster and maximize their business impact.

Senior Manager (AI for Developer Experience) • Zillow Group

SF Bay Area (Remote) • December 2025 - Present

• I’m currently establishing a new team that will be focused on preparing codebases and services for effective contributions by AI agents throughout the software development lifecycle. The mission is to increase engineering productivity through delegating common and repeatable activities to a team of specialized AI agents, enabling software developers to focus on the delivering business impact faster.
• We’re currently focused on:
  • Measuring and improving service/app readiness for headless agent contributions
  • Collecting ground truths datasets for code authoring, code review, deployment, and operations in order to build evaluations and (eventually) model customizations
  • Tool (MCP, Skill) registration and discovery
  • Knowledge discovery for context engineering
  • Fully-managed specialized agents for code review, E2E testing, deployment, and operations
  • Cookbooks for developers to compose custom agents with internal tools and knowledge

Senior Manager (Mobile Apps Platform) • Zillow Group

SF Bay Area (Remote) • October 2021 - December 2025

• Rechartered the Zillow Mobile App Platform team providing foundational architecture and CI/CD systems serving 150 iOS and Android developers at Zillow. Grew the team from 5 developers to 15, and split into highly focused iOS, Android, and infrastructure sub-teams, serving 200+ customers (developers).
• Hired, led, grew engineers and engineering managers across all skill and experience levels – from interns, to Principal engineers, to first-time engineering managers
  
• Architected our macOS CI/CD infrastructure (powering all iOS CI workloads) as well as our Android CI/CD infrastructure, and trained mobile software engineers on the team in AWS and DevOps engineering, growing them into experts in building usable, resiliant, self-healing, and easy-to-operate systems.
  
• Led platform product management programs to deeply understand (and prioritize against) our internal customer needs through developer surveys, telemetry (“productivity vs. frustration signals”), advisory board meetings, pilot programs, and relationship-building with customer EMs.
• Built AI agents and ran “buy-vs-build” pilot programs to rethink end-to-end mobile/app/web testing, and demonstrate with the opportunity to save hundreds of human hours each week, while reducing the count of severe regressions.
• Designed and implemented company-wide mobile app engineering alerting and on-call process, reducing TTA and TTR for mobile app incidents from days to hours.
• Redesigned and implemented mobile app engineering hiring process to re-focus on problem-solving process and practical skills and experience, improving onboarding time and reducing skills deficits on mobile development teams.

• Led project team of web+apps+backend developers to migrate Trulia onto a new search platform and listing data pipeline to improve performance and comply with MLS requirements.
  
• Cross-trained mobile app engineers on backend engineering and GraphQL subgraph development and deployment, so that our mobile developers could contribute to “the whole stack,” reducing interdependencies between teams and breaking down knolwedge silos and “developer centrality.”
• Led cross-organizational team evaluating, building, and deploying CICD platform for iOS engineers.
  
• Coached and supported SDEs in successful achievement of career development objectives, including transition from IC to EM, changes in primary discipline, and expansion of scope and influence beyond our team and organizational unit.

More about me!

I have been involved in the animal shelter/rescue world for over 10 years developing adoption and volunteer programs, building technology solutions, serving as a board member, organizing fundraisers and events, and assisting with shelter dog enrichment and behavior work. I currently spend my weekends at Oakland Animal Services introducing shelter dogs to potential adopters, leading dog playgroups, and building and maintaining websites, web applications, and data pipelines. I’m proud of the software development work our small team has done to drive more adoptions, reduce shelter animal length of stay, and increase live outcome rates. I’m excited also to be developing AI Use Cases with the City of Oakland, and designing strategically-deployed AI agents to help our incredibly talented and dedicated staff “do even more with less” during the ongoing budget crisis.
