01—TRUSTED BY
02—CAPABILITIES

Two Design Paths. One Execution Standard.

Every engagement ships production-grade — whether it starts with AI-accelerated or human-driven design.

01

Technical Scoping & MVP Architecture

We map technical decisions before development starts so your build is delivered on time, on budget, and without surprises.

02

Production UI/UX & Design Systems

Production-ready UI/UX and design systems built for execution. We design with code structure in mind, so every component translates cleanly into fast, maintainable interfaces.

03

High-Performance Web & Mobile Engineering

High-performance web and mobile engineering from concept to deployment. Full-stack expertise across every major framework, with clean architecture and production-grade infrastructure built to scale.

03—AI AS ACCELERATOR

Supervised by our principal architect. Never replaced.

AI coding agents handle boilerplate. Our principal architect focuses 100% on complex logic, security, and custom business rules.

05—THE PRINCIPAL

Every build is architected by the principal.

I'm Kelvin, founder and the principal architect behind Onion Creative. I've spent 12+ years shipping enterprise-grade digital projects for brands like Swire Properties and AXA Asia. Every engagement is architected and overseen by me — no account managers, no juniors learning on your budget.

06—HOW WE WORK

From vision to launch, accelerated.

We ground every interface in your brand strategy, validate it in working HTML, and shape every component for how it will be built.

01STRATEGY BEFORE PIXELSWe start with your business goals, user outcomes, and brand positioning — then design every screen to serve those objectives. Interfaces that work, not just look right.
02AI-ACCELERATED PRODUCTIONCreative direction is set by our principal architect. AI coding agents handle wireframing and component generation — supervised at every step. You review working HTML prototypes, not static mockups.
03DESIGN WITH THE BUILD IN MINDEvery component is shaped by how it will be engineered, tested, and maintained — so vision doesn't get lost between design and deployment.
07—EVIDENCE ·

Onion Creative is an outstanding digital project partner. I work with Kelvin closely for the kini mobile website project. Kelvin always presents multiple implementation options so we can choose the best fit and his team can deliver high quality works even under tight schedule. He consistently goes extra miles to ensure superior customer experience. Highly recommended for any web or digital development work!
