Utilise new tools like Artificial Intelligence to increase delivery efficiency

How BJSS makes the difference

Engineering and Design Working in Harmony

Our expertise ranges from user research and product strategy through to full stack engineering, using all mainstream frontend technologies, including React, Next.JS, Angular and Vue.JS. We learn and adapt to user behaviour to create digital experiences that deliver maximum value and accessibility.

Accelerators That Reduce Time-to-value

We use accelerators to get the basics right and start delivering business value quickly. Our range of accelerators across front-end, microservices, CI/CD, QA, and more, take care of cumbersome setup procedures and enable our engineers to deliver at pace.

Embracing the Best Technology for the Best Outcomes

We constantly evaluate tools and techniques to improve developer experience and increase the efficiency of delivery. We have deployed tools like GitHub Copilot to aid everything from a single team to a 300-person programme and learnt how to get the most value out of them.

Trusted to Build National Critical Infrastructure

Our experience of building and running critical infrastructure such as NHS Spine, which brings together 44,000 healthcare IT systems across England, means we can be trusted to engineer quality software to the highest possible standard.

Comprehensive Integration Understanding

We have rich integration experience across complex business and technical environments such as high-performance websites, APIs and microservices based systems, data platforms, and machine learning workloads. Our integration knowledge covers not just on-premise and legacy systems, but cloud native, serverless, and SaaS, too.

A Focus on Quality and Security

We use automation throughout the SDLC, together with DevSecOps practices, threat modelling, test automation and Continuous Integration/Continuous Delivery orchestration to optimise and provide repeatable confidence in the end-to-end quality and security of the systems we deliver.

A Heritage of High-performance, Cloud-native Development

With a long history of working with the major hyperscalers – AWS, Microsoft, Google Cloud – and deep expertise of their platforms, we know how get the best out of cloud technologies architectures, and patterns.

Thought Leaders in Green Software Development

As early adopters of green software development principles, we apply environmentally friendly engineering approaches and techniques to create learner, more energy efficient code and reduce carbon emissions of applications.

We’ve come a long way with BJSS. We’ve bottom-up re-architected the solution, wholesale changed the technology, and moved from a monthly release cycle to a platform that we can use to demonstrate value daily and scale as we grow. We continue to work with them because they add value beyond the technical achievements, bringing expertise in Agile and quality engineering and a collaborative approach to allow us to achieve our ambitions globally.”
