core mission
The platform needed to handle approximately 6 mln new loan disbursements monthly while managing 10 mln closed loans and related transactions.
The existing system of record could not provide the required lending scale at a sustainable cost for continued market expansion.
Different credit products required flexible configurations for interest calculations, repayment schedules, risk parameters, fees, and other lending rules.
Legacy platform complexity created risks around performance, financial calculation accuracy, system stability, and safe delivery of changes at scale.
Expansion into emerging markets depended on establishing a scalable, lower-cost core system capable of supporting both consumer and merchant lending.
Binariks assembled a team of two Senior Java Engineers and two Senior AQA specialists who have both the technical depth and domain understanding required for complex fintech systems.
Understanding the legacy challenge was crucial. Our client's platform, initially launched in 2006, came with a mature but intricate codebase. Our team participated in comprehensive knowledge transfer sessions covering everything from business logic to technical architecture, ensuring we could navigate the complex calculations and dependencies inherent in loan management systems.
We integrated into the client's Scrum workflow, participating in regular open demos for stakeholders and end users. During refinements, our engineers worked closely with the knowledge owners, contributing to active Q&As and detailed developer notes that clarified requirements and uncovered edge cases early.
Binariks' QA specialists participated in requirement analysis, helped refine user stories, and defined test cases that would validate the system's most complex financial calculations.
Our goal was to move beyond feature delivery and address the underlying concerns about system stability, data accuracy, and scalability that were critical to handling millions of loans monthly.
The platform runs on a robust technology stack built for high-volume financial operations:
Our development team delivered critical features that expanded platform capabilities:
We fundamentally improved testing and release stability:
performance benchmark achieved
automated end-to-end tests
The end customer now has a foundation that supports their current scale while providing the flexibility and cost structure needed for their expansion strategy.
More importantly, they have a system that continues to evolve – a platform that grows with their business rather than constraining it.
