We design digital products from first research through to engineering handoff. Every interface is grounded in real user behavior, tested before code is written, and built to ship.
Start a projectProduct design at appssemble is not a phase. It is a discipline that runs from the first conversation about your product through to the final build. Our designers work inside the engineering team, not in a separate department. They attend standups, review pull requests, and adjust screens in real time when technical constraints surface.
The result is fewer handoff problems, faster iteration, and interfaces that get built exactly as designed. We do not produce pixel-perfect mockups and walk away. We stay until the product ships.
We start by talking to the people who will use the product. Structured interviews, competitive analysis, and workflow mapping give us a clear picture of what users actually need versus what stakeholders assume. This produces a product brief, evidence-based personas, and a prioritized feature map that drives every design decision.
Before anything looks good, it needs to work. We define screen flows, navigation structures, and wireframes. Every interaction is mapped out: what happens on tap, on swipe, on submit, and on error. Edge cases are designed here, not discovered during QA. Wireframes are tested with real users before visual design begins.
High-fidelity interfaces built in Figma at the component level from day one. We work with real content. No placeholder text, no stock images, no "final copy TBD." Every screen is constructed from a shared component set that maps directly to what engineering will implement. Interactive prototypes let you test the product before a line of code is written.
A component library is only useful if engineers can build from it. We deliver systems with named tokens for colors, spacing, and typography. Every component has documented states and responsive behavior rules. The system is designed to scale with your product, whether you have 10 screens or 200.
Stakeholder interviews, user research, and an audit of everything that exists today. We build a shared understanding of the problem before proposing any solutions. The output is a product brief that everyone signs off on.
Information architecture, user flows, and wireframes. We define every path through the product, including error states, empty states, and first-time user experiences. This is where most design debt is prevented.
Pixel-level UI in Figma, built on reusable components from the start. We design with real data and real copy. Interactive prototypes go to users for validation. Screens are iterated until the experience is right.
Everything is packaged into a design system your engineering team can run with. Documented components, tokens, responsive rules, and an annotation layer that removes ambiguity from every handoff.
A clear description of what you are building, who it is for, and how you will measure success. Shared with every stakeholder before design work begins.
Every screen, state, and edge case documented. Tested with real users and refined before visual design starts.
Production-ready designs in Figma with clickable prototypes that feel like the real product. Built on components, not isolated artboards.
Reusable components, design tokens, and responsive rules your team can extend as the product grows. Documented for designers and engineers.
Annotated specs, exported assets, and a clear mapping between design components and code. Nothing left to interpretation.
