CROSS-CULTURAL UX

The Interaction Laboratory

High-fidelity chaos and experimental interaction. My personal playground for what production won't let me do, yet.

Next.js · React

Archive

Six case studies and five interactive demos, hand-engineered in Next.js. The portfolio is also the proof of the work.

The portfolio is a design artifact — every decision here ships to production.

Three.js · Rapier

Particle Engine

Five case studies rendered as physics bodies in 3D space. Drag, throw, and collide — click any object to open the work inside.

Testing Rapier WASM as a portfolio navigation layer — no menus, just objects you can touch.

Framer Motion · Web APIs

Micro-Interactions

Linear-style industrial minimalism meets developer-centric brutalism. Four production-ready interactions in one playground.

Testing Framer Motion spring configs that feel premium at 60fps on low-end devices.

D3.js · Next.js

Graph Demo

Force-directed node graph you can drag. Every item is physically connected, and moving one ripples through the network.

Experimenting with WebGL-accelerated force layouts for high-density ESG data viz.

React · CSS

OS Dashboard

Game-engine UI meets tactile skeuomorphism and command-line aesthetics. Draggable windows, terminal panels, retro chrome.

Prototyping windowed UI patterns for multi-panel analyst dashboards.

Betjeman & Barton

Luxury tea house e-commerce. Cursor-follow previews, dropdown nav, product hover overlays.

Cursor-driven interaction models for high-end e-commerce. No framework dependencies.

About

Complexity is the baseline.
Clarity is the achievement.

Most design engineers favor either the canvas or the codebase. My career is built at the exact intersection of both. I don't just hand off specs; I architect the system and engineer the production code.

I build infrastructure for high-stakes environments, ranging from global UI frameworks supporting 7 languages to data-dense research tools for institutional market analysis. Whether establishing scalable design tokens or executing complex mobile motion, I close the gap between visual vision and technical execution.

Off-hours: movie and coffee lover. Also: Instagram storytelling, Etsy product concepts, logo designs, and hunting for new learnings every day. Based in New Jersey, shipping in NYC.

How I Work

Audit & Strategy

  • ▸Conducting cross-functional stakeholder interviews to align technical constraints with user needs.
  • ▸Performing systemic heuristic audits to identify UX debt and architectural inconsistencies.
  • ▸Market analysis focused on token-driven scalability and design-to-code parity.

Systemic Design

  • ▸Engineering-first component logic that prioritizes programmatic state over static mockups.
  • ▸Architecting automated design-to-code pipelines using semantic token structures.
  • ▸Defining motion choreography through high-fidelity, code-based interactive prototypes.

Technical Delivery

  • ▸Executing production-ready pull requests, bridging the gap between design spec and deployment.
  • ▸Enforcing rigorous accessibility standards through automated testing and manual assistive tech audits.
  • ▸Optimizing runtime performance and asset delivery for high-density applications.
  • ▸Post-launch governance to ensure system integrity and long-term component health.
