Custom Software Development

With our "Mobile First" development strategy, backed by our industry leading 1-year warranty against hidden defects, you can rest assured that your project is in safe hands. We constantly bring fresh ideas to the table and help you see the long-term prospects of your product. At the same time we take a pragmatic approach to help you launch as soon as possible. We work extensively with React Native and React JS and encourage using CI/CD pipelines to streamline build-release cycles.

Our developers are mostly local and have at least an undergraduate degree from a recognized college/University in Canada.

Deliver a flawless customer experience

Application development starts with user experience design (UI). We work with our clients to develop applications that meets their requirements, budget and timeline. React JS lends itself front end focussed design above all else. We have also support React with , API, Database and back end development, native mobile apps and hybrid cross-platform apps.


Mobile First Design

iOS, Android, Hybrid with React JS

Your project will be designed with a React JS Mobile First strategy. More than 80% of your website's traffic comes from mobile devices. Therefore, we pay very close attention to the following:

  • Graceful Degradation (how well does your application fail)
  • Performance at low speeds
  • Display of legacy devices (devices 5 years or older)
  • Offline behaviour


Cost Effective

Modular, Fault Tolerant, Scalable

Take advantage of our speed-to-market practices which aims at producing shippable code at the end of each work day. We achieve such efficiency by assigning the right resources for the task at hand. This effectively minimizes the learning curve and your project is delivered on time and on budget.

Speed doesn't mean poor quality. Our design decisions are governed by the pillars of good software engineering - modular design, code readability, code reusability and fault tolerance. As a result, we provide unlimited bug fixes for an entire year from the day your application is launched.
