Morgan Mueller
Product Development Lead, NYC Department of Health and Mental Hygiene
Data visualization engineer: front-end, D3, and design systems for public data products.
I design and build data visualization products: public dashboards, decision-support tools, and the visualization systems behind them. I work end to end, from data modeling and chart architecture to interaction design, accessibility, and the React front-end that ships.
At the Health Department I build public-facing data products that policymakers, researchers, and journalists use in their work. They ship on a schedule and get read closely. I also teach data visualization and computational design at Parsons.
What I do
Data Visualization
- Chart architecture and visual encoding for dense data
- Visualization systems and reusable chart components
- Legibility and accessibility as requirements, not polish
Data Products
- Discovery to launch, with roadmap ownership
- Public dashboards and decision-support tools
- Stakeholder alignment across policy, research, and comms
Engineering
- Front-end build in React, D3, and Vega-Lite
- Data modeling and pipelines behind the interface
- Architecture built to be maintained, not just launched
- D3
- Vega-Lite
- React
- TypeScript
- Python
- SQL
- Figma
- Tableau
- Power BI
- Maps & GIS
- Azure
- Design systems
- Prototyping
- Human-centered design
How I work
I like to hold the whole thread, from the data to the visualization to the implementation, rather than hand it off at each seam. In practice that means prototyping early, designing the data model and the interface together, and treating the codebase as a product surface that has to last. The result is data products that ship faster and hold up longer.

Let’s talk.
I’m always glad to talk data visualization, data products, and public-interest technology, whether you’re hiring, collaborating, or just curious about the work.
Open to data visualization and data product roles, especially in health, civic, or research contexts.
