Established businesses

An initiative to streamline the operational workflows of your organisation can benefit greatly from a bespoke web application. This works well when off-the-shelf solutions are too generic or rigid.


Apart from top-end software engineering, a whole lot more goes into developing and launching successful web applications.

Understanding Your Vision

It is important for us to really understand your short-term and long-term vision. This ultimately helps us make better technical decisions for your product. We cannot overemphasize the importance of this exercise.

MVP Development

Our team can assist with reviewing your product roadmap and implementing a Minimum Viable Product (MVP), and then incorporating stakeholder feedback into the future versions of the product.

User-Centric Web Design

This goes far beyond just pretty aesthetics: a user-centric design is an acknowledgement and appreciation of end-users’ behaviours and desires. Our design team is experienced in creating web applications that users love to use.


Thanks to our web developers’ deep technical expertise with designing scalable databases and software, your web application will be ready for seamless future enhancements without expensive reworks or quirky workarounds.

Ease of Maintenance

Adhering to good practices of programming and documentation coupled with our short development sprints helps us ensure that the web applications we develop are cost-effective to maintain and expand for the long term.


Security and data privacy considerations of a successful web application have to be planned from the very beginning. Technical leads in our team are involved to review and approve the security checklist for every application that we deliver.

Intellectual Property (IP) Protection

Intellectual Property for the software we develop for you will belong to you from day one. Period.

There are four options which you can choose from:
  • Fixed-price fixed-scope model: If you have well-defined requirements and a pre-decided timeline for your project in mind, a fixed-cost model would work best for you.
  • Dedicated team model: If you feel that (a) your project requirements may change over time or (b) you will need to hire specialists for multiple projects over time but you don’t have the budget for it, you can choose to have our dedicated team of experts assigned to you.
  • Time-and-materials model: If you are unable to decide on a fixed scope, timeframe, or cost for your project, you can go for this model so that your project can be divided into smaller phases over time incurring varying costs.
  • Hybrid model: This model works best in situations where there are frequent fluctuations in the project workload or requirements set.
For a more detailed comparison of these models, you can visit our Engagement Options page.
An important step to get started with your web application development project is communicating your requirements to us.
