Design systems, prototyping, and motion built into the product, not bolted on after. Good design isn't decoration — it's the difference between a user understanding your product in ten seconds or bouncing in five. As a UI/UX design agency embedded inside engineering (not a separate vendor handing off static mockups), 4xCode designs interfaces validated with real user research, built as reusable design systems, and brought to life with motion that feels intentional rather than decorative. Because our designers and engineers work together from day one, what gets designed is what actually ships — pixel for pixel.
Collaborative interface design and design systems.
High-fidelity, interactive prototyping.
Production-grade animation and interaction design.
Documenting and testing UI components in isolation.
Core Philosophy
Designers and engineers work in the same team, so your final product matches the design — not a watered-down approximation of it.
We validate design decisions with real usability testing, not just internal opinion.
Design systems are built for the engineering team to actually use, not abandoned in a Figma file no one opens again.
Capability Matrix
Documented, reusable component libraries that keep your product visually consistent as new features ship.
Interactive prototypes for usability testing before a single line of production code is written.
Purposeful motion design that guides attention and communicates state, not just animation for its own sake.
User research and usability testing to validate design decisions with real behavior, not opinions in a meeting.
