Platform + Software Engineering

Platform + Software Engineering

Quality, scalable business-critical technology systems delivered in partnership, to specification, on time and on budget.  

We believe that software engineering is about more than just writing code. Great software platforms are not built by individuals but by teams of highly skilled developers who listen, adapt and work together to create innovative solutions.

A competitive edge

With a focus on quality, agility, and collaboration, we are committed to helping our clients achieve their goals and stay ahead of the competition.

Our built-to-run approach 

Our platform strategy approach is unique. When devising a solution, we ensure that it functions as per specification and considers how it will operate in its environment. Considering High Availability and Operations during the build phase, ensuring minimum service disruption as your business scales. This involves:

1. Software Development practices that ensure high-quality code, such as Test First Development, SOLID principles and DRY

2. Well-Architected Solutions that are robust, secure and scale

3. Continuous Delivery practices with small incremental changes deployed only after passing a rigorous automated test harness

4. Operational tooling such as Centralised Logging; Backup & Restore capability; Monitoring & Alerting; and Application & Performance Monitoring (APM) ensure high visibility into service health and rapid, proactive responses to any anomalies
