New Public is a Non Profit founded by Eli Pariser (The Filter Bubble, MoveOn) focussed on building healthier online spaces.

Public Service Incubator (PSI) is a partnership with an international consortium of public broadcasters to build a publicly governed online social platform the serves the public good and fosters understanding across divides.

* Was the founding engineer of PSI and built much of the platform

* Designed and implemented a modular platform that lets partners experiment with new features safely while keeping the core maintainable.

* Mentored 16 partner developers so they could successfully extend the product independently.

* Recruited 3 engineers to grow New Public's team

* Helped run live pilots with thousands of participants across multiple countries.

After Covid eased, I returned full-time with two co-founders to pursue pro-social online spaces.

* Built a new new pro-social online platform and multiple variants (React Native, Node.js, Firebase) across mobile and web

* Ran live pilots with hundred of participants, including a partnership with the Forward Party

* Bootstrapped by design - we did not seek venture funding to preserve mission alignment

Full time parent during COVID school closures (homeschooling and childcare).

Incubated pro-social alternatives to mainstream social products. Led product, design, and research.

* Built and tested 20+ prototypes (React Native, Node.js, Firebase) across mobile & web.

* Recruited 500+ people for pilots, ran interviews and usability studies to refine the thesis

* Partnered with Braver Angels and other groups to run real world pilots

* Developed a reusable platform that become the foundation for New Public's Public Service Incubator

I joined Facebook in the aftermath of the 2016 election to help them work out how to deal with misinformation and polarization.

* Recruited by notable early employee Kang-Xing (KX) Jin, who had seen my Dispute Finder work at Intel Research

* Defined a new metric for misinformation prevalence that avoided concerns of being "an arbiter of truth" by thinking instead about whether content was broadly trusted.

* Led diagnostics on how low-quality/violative content enters people’s feeds (reshares, recommendations, groups, comments) to enable upstream prevention rather than relying solely on after-the-fact moderation.

* Shipped ranking and product changes that closed multiple pathways by which bad content reached feeds.

* Designed a new site-quality measure that reduced the reach of low quality "made for facebook" content.

* Contributed to rater guidelines and labeling taxonomies for misleading/polarizing/low-quality content

* Reworked comment ranking to reduce prevalence of toxic-but-engaging content and added new UI controls to allow filtering of borderline content
