Web app & SaaS development company in Singapore

A web app is a practical first choice when people use your product at a desk or need to share it through a link. A mobile app fits a product built around the camera, location or daily notifications. Start with the way people will use it: that choice shapes which interfaces and device features need to be built and tested.

For a web product with a rich interface, we work in TypeScript across the front end, back end, database and APIs, using a stack such as Next.js, React, Node.js and PostgreSQL. Teams already skilled in PHP, Ruby or Python have other options in Laravel, Rails or Django. Existing skills affect who can work comfortably on the product after launch.

A shared database is simpler to run; a separate database for each customer suits enterprise buyers with strict isolation or data-location requirements. For sign-in and billing, established services remove substantial edge-case work, while a custom build gives more flexibility for unusual pricing or strict data rules. We help you decide what the first version needs and plan what comes after it.

If your checkout uses SGQR, we set it up to display the label supplied for the payment options you accept. SGQR combines multiple payment QR codes in a single label, so the checkout needs to make that label easy for the customer to use.

A product holding personal data also needs a usable breach-response workflow. Where an organisation assesses a breach as notifiable under the PDPA, it must notify the PDPC as soon as practicable and no later than 3 calendar days after that assessment, and notify affected individuals. We set up an internal record of the assessment and a workflow for those notifications.

Bring what you have, so we can discuss the product and the work needed to build it.

• Users and their jobWho will use the product, how do they do the job today, and what would they stop using?
• Existing assetsGather designs, prototypes, repositories, domain and hosting details, plus access to third-party accounts.
• Data constraintsNote the personal or sensitive data involved and any security reviews your customers require.
• Current alternativesList the competing products or tools your users piece together and what is missing from each.
• First-use contentConsider sample data and empty screens that help a new user reach a useful result.

  Building standard systems from scratch

  Review established services for sign-in, billing and permissions before spending the budget on custom versions.

• !

  Leaving customer separation until later

  Design it into the first version of a multi-customer product to avoid a risky rewrite.

• !

  Applying payment events twice

  Make webhook handlers skip events already processed and avoid depending on the order in which events arrive.

• !

  Releasing without a safety net

  Use a staging environment and test backups so a release or mistake does not immediately become a live incident.
