A leading fintech provider in South-East Asia offers a popular super-app that transforms mobile devices into virtual wallets, serving over 80 million users, 400+ billers, 139,000+ merchants, and 300,000+ community stores. That scale, though, was starting to outpace the infrastructure behind it. The client’s legacy virtual machines struggled to keep up with the demands of a rapidly growing user base, and core app features like “buy load” and “bill-pay” experienced performance issues, including slow response times, frequent downtimes, and limited scalability. The outdated infrastructure lacked the flexibility to support increasing transaction volumes and seamless service availability, directly impacting user satisfaction. Every new feature rollout came with reliability concerns, leading to delays, higher operational costs, and a growing risk of customer dissatisfaction. To remain competitive, the client needed a high-performance, scalable solution that would improve reliability, speed up feature releases, and optimize operational efficiency.
To help the client scale and improve performance, Ascendion containerized the application with Kafka to enhance scalability and responsiveness, giving the platform room to grow without buckling under peak transaction volume.
System reliability was strengthened with automated health checks and better error handling, catching issues before they became outages rather than after. Ascendion also upgraded the iOS and Android apps for a smoother, more efficient user experience. By modernizing the infrastructure end to end, the client achieved faster service rollouts, minimized downtime, and ensured a seamless experience for millions of users, setting the foundation for continued growth.
Tech Stack:
Grew the user base by 15.5% within a year, showing the modernized infrastructure could support real growth rather than just stabilize what already existed.
Cut maintenance costs by 30%, freeing up resources that had previously gone toward firefighting downtime and reliability issues on the legacy virtual machines.
Drove 51% higher user engagement, reflecting a smoother, more responsive experience across core features.
Set the foundation for continued growth, giving the client a platform built to scale alongside its 80+ million users, 400+ billers, 139,000+ merchants, and 300,000+ community stores, rather than one that strains further as demand rises.
