Atom Bank
Challenge
Atom Bank, the UK’s first digital-only bank, sought to accelerate its digital transformation and scale mobile app development without compromising security or compliance. Manual release cycles, siloed vendor teams, and legacy infrastructure slowed innovation. The challenge was to assemble a dedicated, integrated product team capable of delivering new financial features faster, introducing DevOps best practices, and maintaining full compliance with UK banking regulations.

Solution
Pragmatic Coders built a cross-functional 30-person team in Poland, leading both mobile and DevOps operations. Using Kotlin, Swift, Terraform, and AWS, the team re-architected the app’s core systems, implemented CI/CD pipelines, and automated infrastructure provisioning. Deployment cycles were shortened dramatically through continuous integration (Jenkins + Kubernetes), while QA automation ensured consistent reliability.

Results
Pragmatic Coders helped Atom Bank achieve faster delivery and higher efficiency through DevOps automation and mobile app modernization. Deployment time dropped from 2 days to 2 hours, and the mortgage refinancing process was shortened to one week. Automated CI/CD pipelines improved reliability and compliance, saving the bank over £0.4 million in the first year. The partnership remains ongoing, with Pragmatic Coders leading Atom’s cloud and mobile development roadmap.
