I bring 12 years of design experience—five years practicing architecture followed by the last seven years designing digital products. Whether mapping out physical spaces or software systems, I anchor my work in structural logic, high craft, and real-world performance.
I use AI-assisted prototyping and coding to explore ideas quickly and get to working software faster. While AI handles the heavy lifting on execution speed, I take full ownership of the product strategy, UX judgment, accessibility, and overall quality.
Outside of work, I spend my time analyzing architecture, experimenting with generative tech, mentoring designers, and gardening.
Perspective
From the Dominican Republic to New York
I travel to keep my design perspective sharp. Stepping into completely different environments forces me to question my own design assumptions and teaches me how to build for users whose daily lives look nothing like mine.

At Amazon since 2020, I've driven $1B+ in combined customer impact across payments and Alexa mobile. I joined as an intern, returned full time after completing my master's in 2021, and earned two promotions: L4→L5 in 2023 and L5→L6 Senior Product Designer in 2025.

Designing with AI · live demo
I direct. AI accelerates.
A replay of a real working session: the agent scaffolds a prototype in seconds, then I overrule the calls it cannot responsibly make—financial tone over delight, locale-aware money over a hardcoded '$'. AI expands how many variations I can test and shortens the path to working software, but the overarching strategy, customer judgment, accessibility, and final quality remain entirely mine.

What partners say
Charlie's standout superpower is his relentless focus on high standards and ownership. On the UFO Priceblock launches, he'd challenge tech and product teams when decisions optimized for speed at the expense of the customer experience — always respectfully, always backed by data and rationale.
Shipping products is only half the job. True senior leadership is about building up the people around you. Here is how I invest in my teams outside of core design work.
How I work
My Core Principles
Four foundational principles I default to across every project, backed by measurable product outcomes.
01
Design systems mentorship
Ongoing guidance for a teammate on Rio and our other component libraries — helping him lean on existing systems and patterns instead of rebuilding from scratch.
02
Leveling up a designer to L5
Ran a documentation gap analysis on a partner's Figma files, then coached component-development practices, file structure, and tech-team communication until her work reached L5 standards — positioning her for promotion.
03
Career coaching
Talked through long-term career goals with a teammate and helped map concrete next steps for skill development and positioning for growth.
04
Onboarding and transition systems
Built transition documentation for new team members covering product context, decision history, stakeholder maps, system conventions, open risks, and ways of working—then paired it with weekly buddy sessions so organizational knowledge transferred as an operating system, not a one-time handoff.
Outside of work: a recurring panelist at BrainStation's "Starting and Building a Career in UX Design," and I give portfolio feedback to designers who reach out on LinkedIn.
01
Systems over screens
I design components, patterns, and principles — not just pixels. Scalable design systems create consistent customer experiences across touchpoints and drastically reduce engineering debt.
↳ Built & governed the UFO component library — global reviews across 7 countries
02
Clarity over cleverness
Good UX is invisible. I relentlessly strip away cognitive load and visual friction so users can accomplish complex financial or e-commerce tasks intuitively, without getting stuck.
↳ Launched Compare Plans — helped 16M customers choose the right offer
03
Data-driven craft
High craft must meet real-world performance. I validate structural decisions with user research, then partner with data science and engineering to measure long-term metrics and OPS lifts.
The best products emerge when design, engineering, and business speak the same language. I bridge those gaps to ensure someone is always holding a premium bar for the end user.
↳ UFO Cart redesign drove a 7.2% OPS lift and $542MM in customer sales
What it adds up to
One designer, five disciplines, no seams
01
Systems thinking
Patterns and principles built once, reused everywhere — a shared language that scales.
2 design systems02
Motion craft
Micro-animation that dramatizes the real feature, not decoration — every case-study hero proves it.
5 case studies animated03
Craft
Pixel-level attention to type, spacing, and detail — the gap between shipped and shippable.
37+ features shipped04
AI-directed speed
I direct AI agents to move fast, then apply the judgment they can't — taste, tone, and the calls that matter.

Business impact
Design decisions tied to real business outcomes — measured and repeated across products.
