About the client

A multilateral development institution supporting inclusive, resilient, and sustainable growth across Asia and the Pacific. It works with member countries and partners to address complex development challenges, using innovative financial instruments and strategic partnerships to improve lives, build quality infrastructure, and protect the environment.

The challenge

Our key client in the public sector's essential document approval system was hindered by a complex, aging codebase. This poor maintainability and usability needed an extended team to resolve all issues with high impact. CodeLink specialists were embedded into their team to collaborate on implementation. The collective challenge was to navigate the system's technical debt and ensure stability while the entire integrated team was new to the product.

Ensuring Continuity of a Live System
The primary challenge for the newly formed team was to ensure the seamless operation of a live, multi-module system during the transition of ownership. The team needed to guarantee stability for all users who depended on it for daily operations.
Navigating a Joint Learning Curve
Both CodeLink and the client’s personnel were new to the intricacies of keeping the system up and performing while handling the technical debt. This required a highly collaborative approach to simultaneously learn the system, uncover its issues, and deliver improvements together.
Mitigating Risk from Inherited Technical Debt
The previous implementation left behind a very old codebase that lacked modern software engineering practices, resulting in a system that was hard to understand and modify. This created a major obstacle for future development and posed a long-term risk to the application's health.

Why CodeLink?

The client required a partner with proven expertise in stabilizing and enhancing complex enterprise systems across separate teams. CodeLink’s technical strengths directly matched the project's tech stack. This alignment, combined with our focus on delivering high-quality code and proactive communication when working with external teams, allowed us to add value immediately and ensure that together we reached the end goal.

The result

Once combined, the integrated team took ownership of the platform, stabilizing its core modules and delivering immediate value by systematically refactoring the legacy codebase to improve maintainability and performance. Today, the system is live and actively supported by the team, ensuring reliable operation for users of different departments.

Achieved Stability as an Integrated Team
Working as one unit, the team ensured a stable transition of ownership for the platform despite the steep learning curve. This collaborative effort guaranteed that the client’s critical business operations continued without interruption while we jointly worked on a new module.
Established a Foundation for Long-Term Scalability
We implemented a strategic plan to combat the technical debt left by the previous vendor. Our solution focused on improving code quality to the highest possible standard, making sure the platform is more robust, performant, and easier to enhance with new features.
Streamlined Workflows for Enhanced User Experience
Our solution began with a deep analysis of existing workflows to identify user pain points. Based on this, we provided and implemented concrete suggestions to improve the user experience. This resulted in smoother, more intuitive document handling processes, improving adoption and efficiency for all a leading development bank client users.
