Kapital Bank
Modern Mobile Banking for 5M+ Customers Through a Full Product and Platform Modernization for Kapital Bank
What We Did
- Legacy Application Modernization
- Mobile Product and UI/UX Modernization
- Swift and Kotlin Platform Migration
- Dedicated Engineering Team
- Architecture, Infrastructure, and Process Audit
The Challenge
Kapital Bank serves more than 5 million individual customers and 22,000 corporate accounts. As its mobile products evolved, legacy code, technical debt, and disconnected departmental workflows began slowing releases and putting customer experience at risk. The bank needed more than maintenance: it needed modern applications, stronger engineering practices, and a sustainable way for internal teams to ship safely at scale.
Our Approach
Hazah embedded product leadership and senior engineers alongside the bank's internal teams. A four-week audit mapped code quality, architecture, infrastructure risk, and the communication gaps that were delaying releases. That roadmap gave every workstream a clear order: stabilize the foundation, modernize the applications, and improve how teams plan and deliver together.
The mobile codebases were migrated from Objective-C to Swift and from Java to Kotlin, with refreshed application architecture and UI patterns that made future feature work faster and safer. Agile delivery practices replaced fragmented handoffs, while explicit ownership across iOS, Android, QA, and technical leadership helped the bank maintain momentum without sacrificing the reliability expected from a financial platform.
From Legacy Bottlenecks to
Continuous Product Delivery
The modernization connected technology, process, and ownership across the mobile product:
- Objective-C application migrated to a maintainable Swift stack
- Java application migrated to Kotlin for faster Android development
- Modern app architecture designed for reliable feature expansion
- Shared Agile workflows replacing interdepartmental delivery silos
- Embedded iOS, Android, QA, and technical leadership
- Long-term infrastructure and security risk-mitigation roadmap
The Results
- Modernized mobile banking experience supporting 5M+ individual customers
- Platform serving an additional 22,000 corporate accounts
- Nine embedded specialists across iOS, Android, and QA
- Swift and Kotlin migrations accelerated feature delivery and UX improvements
- Development workflows streamlined for efficient, uninterrupted release cycles
- Infrastructure audit established a roadmap for secure, sustainable scale
Final Word
Kapital Bank's transformation was bigger than a code migration. Hazah modernized the product foundation, strengthened the delivery model, and helped internal teams move faster with the reliability a bank serving millions of customers requires.
