Application Engineering

UI/UX Design & Engineering

We research, design, and prototype the interfaces your product runs on, including the ones built around AI features, then hand them directly to the engineers building the software, so what ships matches what was designed.

How We Design Products

One team for research, design, and the build that follows.

UI UX at Devsinc covers user research, wireframing, prototyping, visual design systems, and usability testing, for the software, web, and mobile products we build, and as a standalone engagement for teams that need design work without a full build. As more products include an AI layer, the interface has to communicate what the system is doing and how confident it is, which is a different design problem than a standard form or dashboard.

When we say UI UX, we mean design work done by a team that also ships the code, not a separate design agency handing off static mockups to be interpreted by someone else. You get design decisions made with build constraints already accounted for, not a beautiful file that needs to be re engineered to actually work.

Capabilities

What this team actually delivers

01User Research and DiscoveryUnderstanding who uses the product and what is actually slowing them down, before any screen gets designed.

02Wireframing and PrototypingLow and high fidelity prototypes that let you test the flow before a single line of production code is written.

03UI Design SystemsReusable component libraries and design standards that keep a growing product consistent as new features ship.

04Interaction and Motion DesignThe transitions and feedback that make an interface feel responsive, not just static screens connected by clicks.

05Designing for AI Native InterfacesConversational flows, confidence and uncertainty states, and human in the loop moments, the interaction patterns AI features actually need that a typical interface does not.

06Usability TestingStructured testing with real users to validate design decisions with evidence, not opinion.

07Accessibility ComplianceDesigning for users with disabilities from the start, not as a post launch retrofit.

08Design to Development HandoffSpecs and assets delivered in a form the engineering team can build directly from, since it is often the same team.

Industries

Where this work lands

01B2B SaaSDashboard and admin interfaces designed for daily, high frequency use.

02E Commerce and RetailShopping and checkout flows designed around conversion and reducing drop off.

03HealthcareInterfaces designed around accessibility and regulatory constraints from the start.

04FintechInterfaces for transaction and account flows where trust and clarity matter as much as aesthetics.

05Enterprise SoftwareComplex, data dense interfaces designed to stay usable at scale.

Engagement Models

Two ways to bring us in

Let's Talk

Embedded TeamDesigners embedded in your product team and sprints, working alongside your own engineers or ours.

Full BuildDesign and development from the same team, from initial research through a shipped product.

Process

How the work runs

01Research and DiscoveryUnderstanding users, business goals, and current pain points before any design work starts.

02Wireframes and PrototypesTesting the core flows at low fidelity before investing in detailed visual design.

03Visual Design and Design SystemBuilding the interface and the reusable components that keep it consistent as the product grows.

04Handoff and Build SupportDelivering specs the engineering team builds from directly, with design staying involved through development, not disappearing after handoff.

FAQs

Frequently Asked Questions

Still have a question about scope, timelines, or what you'll receive?

Let's talk

Do you only design, or do you also build what you design?+

Both, when you want it. Design and engineering sit on the same team, so we can hand off specs to your developers or carry the same design straight through to a built product ourselves.

How long does a typical design engagement take?+

Most design engagements run four to ten weeks depending on scope, from initial research through a finalized design system or prototype.

Can you work with our existing brand and design system?+

We extend and build within existing brand guidelines and design systems rather than starting over, unless a redesign is specifically what is needed.

Do you do usability testing with real users?+

Structured testing sessions are part of the process for validating design decisions before they are built.

Do you design interfaces specifically for AI features?+

Yes. Designing for an AI powered feature means handling states a typical interface does not, such as uncertainty and partial results.

Can you design for accessibility compliance?+

WCAG accessibility standards are built into the design process rather than checked after the fact.

What do we actually receive at the end of the engagement?+

Depends on scope: wireframes and prototypes, a full visual design system with component specs, or a shipped product if the engagement includes development.

Ready for design that's actually buildable?

Bring your product idea or your current interface, we will map where research, design, or a full design system moves the needle fastest.
