About / Product designer + prototyper

Designing products through prototypes

I’m Eduardo Lopez, a product designer based in Seattle, Washington. I turn early concepts into testable product experiences across interface design, motion, code, and 3D.

Cortex scan

A scan of what I watch, listen to, think about, talk about, and make with. Point at a segment of the head to read its record; the four parts floating beside it are the ones still being installed.

Hover or select a segment

Eight attached segments and four upgrades in progress, each sampled separately, each carrying its own record. Point at one to read it.

What I’ve been working on

2026 — Interactive portfolio

Created the Three.js environment, Blender assets, motion system, and responsive case-study experiences.

2026 — Wakeup!

Created the no-snooze wake loop, ten mini-games, AlarmKit reliability states, and six-theme system in SwiftUI.

2025 — Workout!

Designed conversational UX for adjusting workout plans, then built the working iOS prototype with SwiftUI and SpriteKit.

2022 — Internal tools

Mapped workflows, conducted user research, and produced wireframes and interactive prototypes for internal teams.

Read the collaboration story

Why there are no screenshots. These tools and the workflows behind them were confidential internal work, so I cannot show the interfaces or identify the company. I can share how I approached the work, who I collaborated with, and what I delivered.

Lead project

Recycling asset workflow

I designed a prototype that brought an asset-recycling workflow into one place: tracking and auditing equipment, deciding what would be recycled, scheduling vendor pickup, and improving the scan-based handoff so assets were less likely to be lost or mixed up.

Collaboration

Research, alignment, and handoff

I interviewed the technicians who would use the tool, synthesized their pain points, and separated useful requirements from ideas that would add friction. I worked with the project manager to define scope, affected teams, stakeholders, and the metrics leadership expected. I then presented the complete Figma prototype and design rationale to product and project managers, engineers, and a company development manager.

Additional internal work

Ordering tool

Repeated the research and design process with its specific team, then modeled projected time savings, labor-cost impact, and organizational reach.

Internal team site

Designed a home for the team’s values, services, safety practices, coverage, organization, and contact paths.

Rapid concept screens

Turned managers’ rough interface ideas into credible screens they could use in stakeholder conversations.

My scope ended at prototype handoff. Across the work I produced low-, mid-, and high-fidelity screens, wireframes, reusable components, and presentation materials in Figma while following the company design system. Engineers owned the technical implementation, and the time, cost, and reach figures were projected impact—not measured post-launch results.
