Digital design system
When a brand has many digital products, each team builds its interface differently. Sinh Vũ turns the identity into a single source of truth for both designers and developers.
We already have a brand guideline; why do we still need a Digital design system?
A brand guideline is a document for people to read; a Digital design system is the machine-readable version of that same identity. The guideline says how the brand should look; the design system makes sure it always looks that way on every screen customers see. Change one color token at the source and the whole website, app and components update with it, with nothing missed.
A brand that looks good on paper still thins out in digital products, for lack of an automatic enforcement mechanism.
Four phases, each clearly timed
Review and token conversion
We inventory all existing digital interfaces, then standardize them into three token layers per the DTCG standard (Design Tokens Community Group, the industry-wide standard).A DTCG JSON token set with light and dark support + a drift report
Building components and docs
From the token set, we build a library of 40-80 core components with all real states, documented in Storybook and mapped one-to-one with Figma.A component library + Storybook + Figma Code Connect
Rollout and governance
We move one pilot product onto the system first, then scale out, with a transparent RFC governance process.A live pilot product + an RFC process + adoption metrics
Long-term support
Regular upkeep so teams do not quietly slip back to manual work.Regular upgrades + quarterly review notes
What you receive
Each document comes with its file format and the reason it helps you.

A single source of truth for color, font and spacing; change one place and the whole system updates.

The development team assembles interfaces from ready-made components instead of coding from scratch.

Complex interface cases have standard solutions ready, no rethinking each time.

Developers view, test and grab component code right in the browser.

Designers and developers look at the same component, ending the gap between what ships and what was drawn.




The system evolves under control, with every change proposed and approved.
Trusted for 17 years
More than 200 brands across 16 industries have trusted Sinh Vũ to shape their identity.

Before you send a brief for Digital design system
Sinh Vũ talks first with your technical team or your developers to understand the technology in use, for example the specific web platform or mobile app, before shaping the tokens (standardized design values such as color, spacing and type size) and components (reusable interface blocks such as buttons and input fields). The deliverables are built so the engineering team can read them and drop them straight into code, not a set of pretty design files the developers have to reverse-engineer.
Yes, but Sinh Vũ needs to agree the basics first, such as color, font and spacing, before building components, otherwise the system has no foundation to anchor to. In this case Sinh Vũ often proposes doing a lean identity-guidelines pass in parallel, so the design system does not have to guess.
The goal of a digital design system is for your team to add screens and use existing components on their own, without asking Sinh Vũ about every small detail. Sinh Vũ hands it over with usage-rule documentation and can provide quick training for the in-house design or engineering team if you need it.
No lock-in. The files are built on common design tools and the tokens export in a standard format that ordinary web and app build tools can read. Your team can keep editing without coming back to Sinh Vũ.
A digital design system is built with component and token thinking from the start, not a pretty interface drawn first and then figured out for code. This is why the step of talking with your technical team always comes before building the system, so both sides speak the same language.
The number of components, screens and the complexity of the digital product vary greatly from business to business, so a flat price list would not reflect the real volume. Sinh Vũ quotes after understanding the product scope and the technical platform you use.
The timeline depends on the product's scale, the number of components to standardize and whether the business already has identity guidelines. The specific milestones are agreed at quoting, based on the real scope discussed.
The tokens and the core design principles are not tied to a specific technology, so they can be reused. What needs redoing is only how the components are implemented in the new technology, which is usually much lighter than building a system from zero.
