Questions

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, not an account-manager layer.

Yes to both. We're a WordPress web developer and WooCommerce web developer, building headless or classic WordPress sites depending on what the project needs.

Yes — as a mobile app developer we build cross-platform apps with Ionic, Angular and Capacitor, so one build covers iOS, Android and web.

Often, yes. We're a pre-approved PSG vendor, and PSG covers up to 50% of an eligible eCommerce or website package for Singapore-registered SMEs.

Often. We can lead a build or slot in as senior hands on an in-flight project.

A considered marketing site is usually 3–6 weeks; a web app or store, 6–12.
