Mar 20, 2025
In a constantly evolving financial sector, staying ahead of the competition requires constant innovation and infrastructure upgrades. This bank’s outdated development infrastructure and tech stack were limiting growth opportunities, impacting their ability to scale internally and externally. The inefficiency was severely affecting the customer experience, both for their internal teams and their clients, and they needed a solutions provider like Horizontal to help.
In addition to these infrastructure concerns, the bank was facing a critical shift from a traditional Waterfall environment to a more modern Scaled Agile/SAFe framework. This transformation was necessary for the organization to stay competitive, but it required careful planning and execution. On top of this, the bank had large amounts of sensitive customer data that needed to be securely migrated and protected during the entire transformation process.
The first step was to build out over 20 agile teams for the bank. These teams were equipped with a variety of highly specialized roles, ensuring the bank had the expertise needed for every facet of their digital transformation. Horizontal staffed over 15 full-stack engineers, skilled in React, Node, Python, AWS, Docker, Kubernetes and other critical technologies. In addition, we placed more than 5 data engineers with expertise in Python, Pyspark, Docker, Kubernetes and AWS, as well as multiple Scrum Masters, DevOps engineers and database engineers to help support the bank’s transformation efforts.
Our team also provided training development resources to ensure that the client’s internal staff was fully equipped to operate within their new agile framework. This ensured a smooth transition to Scaled Agile/SAFe and set the foundation for a more collaborative, efficient and scalable workflow across the organization.
Today, the bank is more agile and scalable, with a modern tech stack that can handle increased revenue streams, secure data migration and faster response times. The successful partnership with Horizontal has allowed them to achieve their digital transformation goals while positioning them for future success.
