UI/UX & Product Design

Who it's for

  • You're building or overhauling a digital product — an app, a SaaS platform, an internal portal — with no in-house designer.
  • Product decisions are currently being made without research, by whoever's in the room.
  • Your UI is getting harder to extend because there's no system behind it, just screens.
  • You want this scoped and run the way your team already scopes sprints — not as an open-ended "creative" engagement.

Product decisions made without research or a design system produce a UI that's expensive to maintain and inconsistent to extend — every new feature either breaks the pattern or invents a new one. This service is framed and priced as sprints, matching how product teams already scope internal work.

Included

Research-backed decisions, not opinion-backed ones

Figma files with a real component structure, not flattened screens

Developer-ready specs (states, spacing, redlines)

Documentation your team can extend without us

Questions about this service

Do you code, or only design?
This service is design and research only, handed off developer-ready. If you also need the build, pair it with Website Design & Development or bring your own team — our handoff is built for either.
What research do you actually do at the Sprint tier?
A structured review of your current flow and analytics (if available), plus a short competitive scan — not user interviews, which start at Full Product Design.
Do I own the Figma file and design system?
Yes, transferred to your own Figma account on delivery, with full editing rights.
Can you join our existing product team's sprint cadence?
Yes — this is common for the Full Product Design tier; cadence and check-in format are agreed at kickoff.

Ship design your developers won't have to guess at.
