木Web & App

We build the structures underneath the screen.

Websites, mobile apps and the quiet infrastructure behind them — engineering you feel only as a product that makes sense.

Good engineering disappears. You notice it as a product where the next step is always obvious and nothing gets in the way. That is the whole brief.

What we do

Fast, considered sites that load instantly and read well.

Company profiles and institutional sites built to be taken seriously, not just seen.

Listings, agent branding and lead capture built for how Singapore property actually gets searched.

WooCommerce and headless storefronts — eCommerce web development built to convert, not just to look the part.

Product interfaces where the next step is always obvious.

Bespoke builds for briefs that don't fit a template — complex integrations, migrations, anything off the beaten path.

One codebase for iOS, Android and web, with native reach where it counts.

Swift and Kotlin, when a build needs everything the platform can give it.

01
Frame the problem
What decision does this product help someone make? Everything follows from that.
02
Design in the browser
Real type, real data, real interactions — not a picture of a screen.
03
Build in vertical slices
Ship something working early, then deepen it. No six-month reveal.
04
Hand over
Clean code, documentation, and a walkthrough so it's yours to run.

: An agency now — Calvin Seng Co, a registered Singapore company (UEN 201708347K) working since 2008. It began as freelance web design and web development work and grew into a studio; today you get an agency's reliability with direct access to the senior people on your project, not an account-manager layer.
: Yes to both. We're a WordPress web developer and WooCommerce web developer for Singapore businesses, building headless or classic WordPress sites depending on what the project actually needs.
: Yes — as a mobile app developer we build cross-platform apps for Singapore businesses with Ionic, Angular and Capacitor, so one build covers iOS, Android and web.
: Often, yes. We're a pre-approved PSG vendor, and the Productivity Solutions Grant covers up to 50% of an eligible eCommerce web design and development, or website, package for Singapore-registered SMEs. We'll tell you honestly if your scope qualifies — see the full PSG grant breakdown for the numbers.
: Often. We can lead a build or slot in as senior hands on an in-flight project.
: Yes — the first step is a short audit so we both know what we're inheriting.
: A considered marketing site is usually 3–6 weeks; a web app or store, 6–12. You see working slices the whole way, not a single reveal at the end.
