I design complex systems for
clarity, trust, and action.

I build AI-enabled, data-intensive, and technical products from early product definition through front-end implementation.

Designing tools for complex decisions

Clinical trial platforms, biomedical visualization tools, and AI-assisted research systems, built for the people who use them every day.

AI-Powered Clinical Trial Matching
Echo · 2026
A platform for matching patients to clinical trials. Designed transparent eligibility logic, cohort dashboards, and AI explainability features for research coordinators at Yale Medicine.
Outcome A clearer way to inspect eligibility logic, compare cohorts, and understand AI-generated decisions.

Biomedical Data Exploration
MedViz · 2026
An interactive visualization platform for biomedical literature and genomic datasets. Built to give researchers a faster path from raw data to interpretable insight.
Outcome A cohesive exploration system that makes large biomedical datasets easier to navigate, compare, and explain.

AI-Enabled Campaign Operations Platform
PrintCore · 2026
An AI-enabled campaign operations and intelligence platform that helps enterprise marketing teams move from strategy to launch-ready campaigns faster, then learn from every campaign.
Outcome A governed workflow connecting campaign creation, sales validation, agency comparison, and continuous learning.
PrintCore Campaign OS, an AI-enabled campaign operations platform

My favorite work starts before the solution is obvious.

I turn ambiguous requirements, complex workflows, and dense information into usable products, guiding them from early product definition through design and front-end implementation.

How I design for complex systems

01 — Structure the problem
Information architecture

Structure before screens. I map information, decisions, dependencies, and user needs before defining the interface.

02 — Understand the data
Data as material

The data shapes the experience. I use the structure, limits, and meaning of the data as a foundation for interaction and visualization design.

03 — Build scalable patterns
Systems thinking

Design the system, not just the screen. I create reusable components, interaction patterns, and product rules that support consistency as the product grows.

04 — Prove it in the build
Build & prototype

The design lives in the build. I prototype and implement interfaces in code, testing interactions and technical constraints before they are lost in handoff.

Let's build what's next

I'm always happy to talk through a new project or collaboration. If there's something you're trying to build, get in touch.
