Challenges
Navigating the complexities of integrating modern backend solutions with outdated banking infrastructures.
Building a backend architecture capable of supporting rapid growth and fluctuating transaction volumes.
Addressing stringent regulatory requirements while safeguarding sensitive financial data.
Ensuring fast and reliable data exchange between systems to support seamless client servicing and integration.
Solution
We seamlessly integrated modern APIs with legacy banking systems by developing a custom middleware solution, ensuring uninterrupted data flow without disrupting existing infrastructures. Additionally, our microservices architecture provided the scalability needed to handle dynamic transaction volumes efficiently.
Furthermore, to optimized performance, we implemented an advanced API gateway with rate limiting, load balancing, and real-time monitoring. This approach not only enhanced data exchange between systems but also delivered a consistently smooth and responsive user experience.
On top of that, we embedded automated security protocols, including data encryption, role-based access controls, and compliance checks, effectively safeguarding sensitive financial data while adhering to regulatory requirements.

The nexus development process
BACKEND ARCHITECTURE & PLANNING
We began by conducting a comprehensive technical analysis to define the backend requirements for the Nexus platform. Our team focused on legacy system integration, API management, and data security protocols. This phase involved designing a scalable microservices architecture, establishing a robust API gateway, and ensuring compliance with financial regulations through secure authentication and authorization methods.
1BACKEND DEVELOPMENT & INTEGRATION
During development, we built a resilient backend system featuring middleware solutions to connect legacy banking systems with modern APIs. Our team developed over 50 API endpoints, enabling seamless data flow and automation of key processes, from pre-trade execution to post-trade reporting. We also implemented advanced transaction monitoring tools to enhance performance and maintain system stability.
2OPTIMIZATION & DEPLOYMENT
In the final phase, we rigorously tested the backend infrastructure to ensure high performance and compliance. Utilizing Docker and Kubernetes, we achieved 99.9% system uptime and robust scalability. Our CI/CD pipeline allowed smooth deployment, while real-time monitoring tools provided ongoing system visibility, ensuring long-term reliability and operational excellence for Nexus.
