Our Technology

We leverage the latest tools and technologies to create a seamless, customer‑centric digital experience.

Infrastructure as Code is fundamental to our approach, and we use Terraform to manage our cloud resources.

Our architecture is cloud‑native, event‑driven, and distributed, built on Amazon Event Bridge and SQS, with services exposed via REST. We are driven by data science, machine learning, and analytics, using multi‑variant testing to personalise user experiences across every digital channel.

However, it’s not just about the technology. We are passionate about continuous delivery, automation, and rapid iteration. Our deployment pipeline is fully automated, covering everything from branching, building, testing, and shipping to monitoring and alerting—allowing us to focus on delivering value to our customers.
