Banking Application Optimization Journey
Datayaan optimized a leading US bank’s digital banking platform to improve performance, stability, and security, delivering higher compliance, efficiency, and customer trust.
Overview
One of the leading banking majors in the US operated a large-scale web and mobile banking application supporting high transaction volumes and critical customer-facing services. As usage increased, the bank faced growing challenges related to system availability, transaction stability, performance efficiency, and security compliance. To ensure uninterrupted banking services and maintain customer trust, the bank partnered with Datayaan to optimize its application architecture, improve observability, and strengthen governance across its digital banking ecosystem.
The Challenge
The bank faced challenges in maintaining consistent system availability, transaction integrity, and security across its web and mobile banking platforms. Increasing transaction loads exposed inefficiencies in application code, error handling, and server resource utilization. Excessive and noisy error logs made it difficult for operations teams to quickly identify and prioritize critical issues, leading to delayed incident resolution.
Additionally, decentralized API management and inconsistent deployment configurations increased governance complexity and posed security and compliance risks in a highly regulated BFSI environment.
The Solution
Datayaan conducted a detailed root cause analysis to identify performance bottlenecks and instability issues within the banking application and optimized the codebase to ensure stable and reliable transaction processing. Error logging levels were refined to reduce noise in operational dashboards, allowing teams to focus on critical warnings and errors that required immediate attention. The logging framework was further enhanced to improve prioritization and visibility of high-impact issues.
Datayaan also centralized API management by implementing standardized governance, security controls, and integrated testing and deployment configurations, ensuring consistent enforcement of policies across environments while strengthening the overall security posture.
Impact
Increased customer retention rate by 20%
Attained 100% compliance with industry security standards
Optimized server CPU usage from 40% to 30%
Outcome
The banking major achieved a more resilient, secure, and performance-optimized digital banking platform. Improved observability, centralized governance, and efficient resource utilization enabled faster issue resolution, higher customer satisfaction, and long-term operational stability across its digital channels.
