# UI/UX & Product Design

> UI/UX and product design services: research-led flows, design systems, and high-fidelity prototypes that hand off losslessly to engineering. By Sentient Arc.

Research-led product design: user flows, design systems, and high-fidelity prototypes built to convert and engineered to hand off without loss.

## Opinion is not a design process
When design decisions are settled by taste and seniority, the interface optimizes for the meeting where it was approved, not the user who has to get through it. Dribbble-ready, conversion-poor.

The second failure is quieter: design produced far from engineering looks finished but cannot be built as drawn, and what ships ends up a lossy translation nobody approved.

## Research decides, prototypes prove
We put evidence at the head of the process: before anything is drawn, the team knows who the user is, what they are trying to do, and where the current experience fails them, because we went and looked.

Decisions get tested in prototypes before they cost engineering time, and everything ships as a system: components, tokens, and documentation that survive the journey into code intact.

## What we build
- **Product & interface design**: User flows, high-fidelity screens, and edge-state coverage that holds up beyond the happy path.
- **Design systems**: Token-based component systems that keep product surfaces consistent as the team scales.
- **Prototypes & motion**: Interactive prototypes and motion studies that answer product questions before code is written.
- **UX research & audits**: Interviews, usability tests, and conversion audits that locate where a product actually loses users.

## Stack
- **Research:** User interviews, Usability testing, Journey mapping
- **Design:** Figma, Design systems, High-fidelity prototyping
- **Motion & handoff:** Framer, Rive, Webflow, Design tokens

## FAQ
**What do your UI/UX design services include?**

User research, product and interface design, design systems, interactive prototypes, and engineering handoff with tokens and specs, run as one evidence-led process from question to shipped screen.

**How does design connect to development?**

Through design systems and tokens engineers consume directly, specs annotated for real data and breakpoints, and implementation review, so the shipped product matches the approved design.

**Do you run UX audits on existing products?**

Yes. An audit maps where the product loses users, through usability sessions and funnel analysis, and returns a prioritized fix list, which is often the cheapest way to start.

**What makes a design system worth building?**

More than one surface and more than one person shipping UI. Below that, a disciplined component file is enough; past it, a token-based system pays for itself in consistency and speed.
