I have spent more than 15 years working across the stack, leading Android initiatives, Kotlin migrations, and production infrastructure projects. I enjoy solving complex engineering problems and shipping features that improve user experience and developer productivity. At Meta, I have worked on Messenger and Facebook production infrastructure, led large client infrastructure projects, refactored core messaging surfaces, and helped drive Java-to-Kotlin conversion efforts. I also led a major Android 17 upgrade across multiple teams and contributed to agentic development workflows. Previously, I worked at AbleTo, where I led Android development for a native app transition, contributed to CI/CD pipelines, supported Play Store deployments, and helped grow the team through interviews and technical leadership. I also worked at Willowtree, Ticketmaster, Two Toasters, and FireApps, building Android products, reusable architectures, and developer tools. My background includes open-source work such as ReduxKotlin, which I created as a Kotlin Multiplatform implementation of the Redux pattern for shared application architecture. I have also contributed to patents, award-winning projects, and educational talks at meetups and conferences. I value collaboration with product, design, data, and engineering teams, and I bring a strong mix of technical leadership, mentorship, and hands-on implementation. I am especially interested in building scalable mobile systems and modernizing applications with clean architecture and thoughtful engineering practices. ## Professional area ### [Developer & Engineer](https://jobicy.com/resume-category/dev.md) ## Skills ### [A/B Testing](https://jobicy.com/resume-skill/a-b-testing.md)[Android](https://jobicy.com/resume-skill/android.md)[CI/CD](https://jobicy.com/resume-skill/ci-cd.md)[Kotlin](https://jobicy.com/resume-skill/kotlin.md)[Mobile Testing](https://jobicy.com/resume-skill/mobile-testing.md)[Public Speaking](https://jobicy.com/resume-skill/public-speaking.md)[Redux](https://jobicy.com/resume-skill/redux.md)[Software Development](https://jobicy.com/resume-skill/software-development.md)[Software Project Management](https://jobicy.com/resume-skill/software-project-management.md)[Stakeholder Management](https://jobicy.com/resume-skill/stakeholder-management.md) ## Education 2003 Environmental Studies / Environmental Policy @ University of North Carolina at Asheville ## Experience Jul 2023 - Current Senior Software Engineer @ Meta Worked on Messenger and Facebook production infrastructure; led large client infrastructure projects in the xapp codebase; refactored Composer; designed and implemented the FeatureConfig system; championed Java-to-Kotlin conversion efforts; led Android 17 upgrade for Messenger across multiple teams; handled on-call responsibilities; contributed to agentic development with Claude Code and other AIs.
