- Reduced new bank/building society onboarding time to under 30 days post-UAT.
- Cut deployment overhead by over 70% by removing tenant-specific code changes.
Multi-TenantCore BankingConfigurationDocker
OverviewExpand
Consolidate is a configurable banking platform designed for UK banks and building societies. The goal was to move away from separate client-specific codebases and create one platform that could adapt to each tenant through runtime configuration.
The ChallengeExpand
Each client had different screens, product rules, labels, flows, and behavior. Keeping those differences in separate codebases made onboarding slower, deployments riskier, and maintenance harder as the client list grew.
The SolutionExpand
I worked on a single configurable platform where tenant-specific behavior could be controlled at runtime. Screen labels, page flows, button states, and product-type logic could be adjusted per tenant without changing application code.
Technical DetailsExpand
Built the platform around tenant-aware configuration rather than hardcoded client branches.
Supported banking product differences such as savings, ISA, and mortgage flows.
Kept API behavior and frontend flows aligned through shared configuration contracts.
Used Docker to keep environments repeatable across clients and deployments.
ResultsExpand
- New tenants could be onboarded in under 30 days after UAT.
- Deployment overhead dropped by over 70% because client differences no longer required repeated code changes.
- The platform created a cleaner foundation for scaling future UK banking and building society clients.
