Product Interfaces
React and Next.js applications built for the people who use them daily, not for a screenshot.

Service / Full-Stack Delivery
Ship The Whole Product, Not Just The Backend
Interface, API, database, and deployment delivered by one team, so nothing gets lost in the gap between contractors.
- Whole stack
- One team
- Client to database
- Typed
- WCAG-aware
- Accessible
- Core Web Vitals
- Fast
What is included
Inside Full-Stack Delivery
The concrete pieces of work an engagement covers.
Design Systems
A token-driven component library so the tenth screen costs a fraction of the first.
Consistency002
Type Safety
One contract from database row to rendered component, enforced by the compiler.
Reliability003
Performance
Real Core Web Vitals budgets, measured in CI, enforced before merge.
Speed004
Accessibility
Keyboard paths, focus management, and contrast handled during the build.
Access005
Deployment
Preview environments per pull request and a production deploy anyone can trigger safely.
Delivery006
Unique approach
One Team, Whole Stack
The expensive bugs live in the seams between teams. We remove the seams.
With DarCode
- One team owns client through database
- Types shared across the entire stack
- Performance budgets enforced in CI
- Accessibility handled during the build
- Preview environment on every change
- Design system built before screen ten
Typical alternative
- Three vendors pointing at each other
- API shape rediscovered by reading logs
- Performance reviewed once, before launch
- Accessibility audit filed as future work
- Review by screenshot in a chat thread
- Every screen re-solved from scratch
How it runs
From Kickoff To Handover
The same sequence every time, compressed or extended to fit the engagement.
- 01
Frame
Agree the core flows and what the product must do before pixels or schemas.
- 02
Prototype
A clickable path through the main journey, built in the real stack.
- 03
System
Tokens and components extracted once the patterns are proven, not guessed.
- 04
Build
Feature by feature, each shipped behind a flag with its own preview.
- 05
Launch
Performance, accessibility, and analytics verified before the flag comes off.
Tooling

FAQ
Frequently Asked Questions
Questions we get asked about full-stack delivery.
We do product and interface design. For heavy brand work we collaborate with a specialist studio or your existing brand team.
React with Next.js and TypeScript by default. If your team already runs something else and runs it well, we work in that.
Yes. We start with an audit, agree what to keep, and improve incrementally rather than proposing a rewrite by reflex.
Responsive web first. For genuine native requirements we scope React Native or a platform-native partner.
