Approach

Water is the throughline of my work — from managing partnerships in the water and wastewater industry to graduate research in ocean data, seafloor mapping, and ocean governance. This portfolio showcases how I use data analysis and visualization across both.

01

Discovery & Analysis

Understanding data structure, relationships, and analytical goals through exploratory analysis.

02

Design & Prototyping

Creating visual systems that balance aesthetic refinement with functional precision.

03

Development & Testing

Building responsive, performant visualizations with rigorous accuracy validation.

04

Documentation & Handoff

Comprehensive technical documentation and knowledge transfer for maintainability.

Let's Collaborate

Available for consulting projects, speaking engagements, and collaboration on visualization systems that demand both technical precision and design excellence.
