Project Goals

The Bond Trading Platform Development project aimed to create an innovative and accessible trading solution for an investment company operating in the bond market. The platform's focus was to offer trading capabilities through mobile devices, enabling emigrants and investors in Russia to trade bonds conveniently. Integration with the Moscow Exchange and government services ensured that the platform provided legally significant actions with high reliability, making it a pioneer in its segment.

Functional Capabilities

  • User-Friendly Trading Interface: Developed an intuitive interface for users to easily conduct trading activities, allowing them to navigate the bond market with ease. The interface was designed to minimize the complexity of trading while ensuring users had access to all necessary features.
  • Mobile Accessibility: Created mobile applications for both iOS and Android platforms, enabling investors to trade bonds on-the-go. This made trading accessible to a broader audience, providing flexibility and convenience in trading activities.
  • Integration with Government Services: Implemented integration with government services, ensuring that users could perform legally significant actions directly from the mobile app. This included identity verification and compliance, streamlining the onboarding process.
  • Integration with the Moscow Exchange: Integrated with the Moscow Exchange to offer a comprehensive range of trading options, allowing users to access a variety of bonds directly through the platform.
  • Hardware Integration: The platform included hardware integrations to ensure efficient execution of trades, enhancing both the speed and reliability of transactions.

Solution Concept

The bond trading platform was developed to provide a seamless experience for investors looking to trade bonds through mobile and web applications. The initial requirement was to create a solution that allowed trading through mobile devices, making it a suitable choice for users who needed to trade while in emigration or without physical access to traditional brokerage services.

The backend was developed using Python and Django, offering a secure and stable environment for managing trades, user accounts, and financial transactions. The system utilized Django REST Framework and aiohttp to create a scalable API, facilitating smooth communication between mobile clients, web clients, and backend services.

The frontend was built using AngularJS for the web and Objective C for iOS, along with Java for Android. The mobile applications were designed to be responsive, easy to use, and capable of performing complex financial transactions while maintaining user trust and data security.

The infrastructure included PostgreSQL and MongoDB for data management, Redis for caching, and Celery for task management and job scheduling. The platform was designed with a microservices architecture to allow for the independent scaling of various components, ensuring that the system could handle sudden increases in user activity or transaction volume.

To ensure high availability and reliability, the project utilized Kubernetes for container orchestration, enabling the team to scale services dynamically as needed. The CI/CD pipeline was managed through Jenkins, ensuring continuous delivery and integration of new features and updates.

Results

  • Enhanced User Experience: The trading platform featured a simple and intuitive user interface, making it accessible to new investors while still providing all the necessary tools for experienced traders.
  • Convenience through Mobile Trading: The mobile applications allowed users to trade bonds from anywhere, providing flexibility and expanding the customer base, particularly for those trading from abroad.
  • Efficiency through Government Integration: Integration with government services ensured that users could comply with legal requirements directly through the app, simplifying onboarding and increasing the platform's credibility.
  • Expanded Trading Options: Integration with the Moscow Exchange provided a wider range of trading options, giving users access to multiple types of bonds and allowing them to diversify their portfolios.
  • High Security and Reliability: Hardware integration and the use of industry best practices in software security made the platform a reliable and secure environment for financial transactions, reducing risks associated with trading.
