As the microfinance bank expanded its digital services, its software delivery process became increasingly complex.
Development, project management and infrastructure activities were operating across different stages of the technology lifecycle, creating unnecessary handoffs and making it difficult to maintain a consistent path from a development task to a production release.
At the same time, the bank needed to modernise its technology environment without introducing unnecessary infrastructure and operational costs.
BuildByRex was engaged to redesign the software development lifecycle and establish an Azure-centric engineering platform that could support reliable application delivery while remaining commercially conscious.
Rather than introducing isolated DevOps tools, BuildByRex redesigned the end-to-end development lifecycle.
We established a connected delivery model in which a development requirement could progress through a controlled sequence:
Plan → Develop → Review → Build → Test → Release → Deploy
Azure became the core platform around which the delivery architecture was designed, with automation and managed services used where they provided clear operational or economic value.
The architecture was deliberately designed around three principles:
Remove repetitive manual activities from the delivery process.
Create reusable patterns for application development and deployment.
Select cloud services and deployment models based not only on technical capability, but also on their operational and financial impact.
The implementation was primarily built around the Microsoft Azure ecosystem, complemented by modern application development and DevOps technologies.
Azure provided the foundation for the cloud infrastructure and application delivery platform.
Key Azure capabilities were leveraged across areas such as:
The platform supported modern application delivery patterns including:
The objective was not to maximise the number of technologies used, but to establish a coherent technology stack where each component had a defined purpose.
A significant consideration throughout the implementation was cost optimisation.
Cloud adoption can easily result in higher infrastructure expenditure if services are selected without considering workload characteristics, utilisation and operational requirements.
BuildByRex therefore evaluated the architecture from both an engineering and financial perspective.
Compute resources were selected according to actual application requirements rather than simply provisioning oversized infrastructure.
Azure managed services were considered where they could reduce infrastructure administration and operational overhead.
This allowed the engineering team to focus more on application delivery rather than maintaining underlying infrastructure.
Containerisation provided a consistent application packaging model and created greater flexibility in how workloads could be deployed.
It also allowed infrastructure capacity to be aligned more closely with application requirements.
Development, testing and production environments were designed with their respective usage patterns in mind rather than treating every environment as a production-scale workload.
This helped avoid unnecessary expenditure on lower environments.
Automation also contributed to cost control.
By reducing manual operational activities and standardising deployments, the bank could reduce the engineering effort required to maintain and release its applications.
The goal was not simply to move the bank to Azure—it was to build an Azure environment that made commercial sense.
The transformation began at the point where development work was created.
Tasks were structured around clear requirements, ownership and priorities, providing developers and project stakeholders with a common understanding of what needed to be delivered.
This established the first connection between what the business wanted to achieve and the software being developed to achieve it.
The development workflow was reorganised around structured source-control practices.
Developers could work independently while changes were brought together through controlled review and integration processes.
This established a clearer path from:
Developer → Code Change → Review → Integration
BuildByRex implemented Continuous Integration pipelines that automatically processed application changes.
Once changes were integrated, pipelines could perform the required build and validation activities without developers having to manually repeat each step.
This created an executable and repeatable definition of how applications were built.
The build process was connected to deployment pipelines.
Applications could progress through defined environments using automated delivery processes rather than relying on individual deployment procedures.
This created a more predictable release mechanism while reducing manual intervention.
Build and deployment outcomes became part of the development process.
Issues could therefore be identified earlier, allowing teams to address them within the same delivery lifecycle rather than discovering them much later in the release process.
