Capabilities • Expertise
I partner closely with early-stage startups and enterprise design teams to ship robust, functional, and gorgeous software solutions.
UI & Interface Engineering
Pixel-perfect interface layouts focused on utility, typography, and optical alignment. Multi-screen adaptivity, robust dark states, and logical interaction flows.
Design Token Systems
Building systemic design architectures linking Figma variables directly to Tailwind, CSS, or React properties. Perfect consistency, documented rules, and easy maintenance.
Interactive Prototyping
High-fidelity gesture prototypes demonstrating precise curve animation, state changes, and spatial relation, bridging the gap between design and production.
Product Strategy & Logic
Transforming technical complexity and nebulous user requirements into clear, sensible interfaces. Aligning technical limits with direct human usability.
Alex Rivera
I approach digital product design as a synthesis of engineering logic and visual restraint. Before freelancing, I spent years leading feature designs inside Stripe and Linear, refining the core principles of high-utility systems.
Based out of San Francisco, working globally. I build and design concurrently, allowing code constraint to guide aesthetic design and vice-versa.
Independent Product Designer
