UI/UX & Product Design
Research, flows, and interfaces built with the engineers who ship them.
In short
Sparza designs product interfaces alongside the teams that build them, working inside your codebase from the second week rather than handing over flat files. We map the jobs that actually carry your value, rebuild around them, and let the design system emerge from shipped work instead of preceding it.
You probably need this if
- Customers buy on the demo and then churn during onboarding.
- The same action can be performed three ways because three teams built it separately.
- Every new feature widens the gap between what your product does and what people can find.
- A previous design system was built, adopted by nobody, and quietly abandoned.
What’s included
- Research. Task-based sessions with real users, plus a behavioural read of what people already do in the product.
- Audit and architecture. Every screen catalogued, duplication mapped, and the core jobs identified and prioritised.
- Interface design. Flows and screens for the paths that matter, designed against real data and real edge cases.
- Design system. Components extracted from shipped work, so each one has proven demand behind it.
- Accessibility. Keyboard paths, focus order, and contrast handled per component as it enters the library.
How the work runs
Audit and discovery
Screens catalogued, customers shadowed through real tasks, product teams interviewed.
Direction
Core jobs defined, primary paths mapped, and two directions tested with actual users.
Design and build
One job at a time, designed and shipped in sequence so each is validated before the next starts.
System consolidation
Library documented, accessibility verified, ownership transferred to your product teams.
What you get
- Research findings with recorded sessions
- Screen audit and consolidation plan
- Primary workflow designs, end to end
- Documented component library
- Accessibility specification per component
- In-codebase implementation and handover

Common questions
Do you work in our repo or in design files?
Both. Design happens where it is fastest to explore, but our design technologist works inside your codebase from around week three, so components are specified in the medium they ship in rather than translated later.
Will you delete features our enterprise customers rely on?
No. Enterprise customers depend on obscure functionality in ways no audit fully reveals. We demote rarely-used features into a consistent, searchable secondary layer instead of removing them.
Can you work alongside our in-house designers?
Yes, and it tends to produce the better outcome. The system survives because your team helped build it rather than receiving it finished.
