Lonvest is a P2P investment platform focused on the European market. Our main task was to create a service that would allow investors to choose the country they are interested in investing in and receive passive income. Artjoker was responsible for providing a full-circle software development solution for Lonvest.com to overcome these challenges.

Business challenges:

  • Artjoker's task was to help the client build a convenient and secure P2P investment platform.
  • Reduce AWS Costs: Identify and implement strategies to lower monthly AWS expenses without impacting service quality.
  • Optimize Infrastructure Performance: Enhance the efficiency and reliability of our infrastructure to support scalable growth.
  • Automate Resource Management: Leverage automation to manage resources more effectively, ensuring optimal performance and cost-efficiency.
  • Implement Best Practices: Adopt AWS best practices for security, compliance, and architecture.

Our Solutions:

To overcome the business challenge, Artjoker needed to address several technical challenges, including:

  • Project Architecture: Artjoker needed to develop a complete project architecture that included user requirements and a back office for accounting transactions and payments to clients.
  • KYC/AML: The platform needed to use modern Know Your Customer (KYC) and Anti-Money Laundering (AML) systems to identify clients.
  • 2FA Authorization: To ensure the security of client login and protect client credentials, we implemented two-factor authentication (2FA) authorization.
  • Automatic API Integration: To streamline the process of exchanging loan data with loan providers, we implemented an automatic API integration system.
  • Personal Account and Dashboard: we created a personal account and client dashboard that allowed clients to track the progress of their investments.
  • Notification System: we implemented a notification system that informed clients about their lifecycle in the system, from registration to investment and income generation.
  • Mobile Version: we created a mobile version of the platform that duplicated the client's experience and made it convenient.
  • Modern Interface: To match other competitors in the market and create a better user experience, we created a modern interface.

Detailed Cost Analysis:

We conducted a thorough AWS billing and usage analysis using AWS Cost Explorer and AWS Budgets to identify high-cost resources and services, pinpointing areas for cost reduction.

Right-Sizing and Reserved Instances:

By right-sizing EC2 instances and RDS databases to match actual usage and purchasing Reserved Instances for predictable workloads, we achieved significant monthly AWS cost reductions.

Cleanup and Decommissioning:

Implementing a process to regularly review and decommission unused resources, such as unattached EBS volumes and obsolete snapshots, contributed to cost savings.

Cost Allocation Tags and Monitoring:

We implemented detailed resource tagging for precise cost tracking by department, project, and environment, facilitating informed budgeting decisions and accountability.

Continuous Monitoring and Optimization:

Utilizing AWS Trusted Advisor and third-party tools enabled ongoing monitoring and recommendations for cost optimization, security, and performance.

Technology stack:

Artjoker's team utilized a variety of programming languages, frameworks, and technologies to create the Lonvest.com platform. The front-end of the platform was built using JavaScript, ReactJS, and Redux, while the back-end was built using Node.js and Express.

  • For the database, we utilized MongoDB, specifically MongoDB Atlas. Integration unit tests were conducted using Jest and Enzyme, while Git and Github were used for version control. Our team also implemented CI/CD with CircleCI to ensure the platform's stability and reliability.
  • To deploy the platform, we utilized Docker, which enabled the team to create a containerized environment for the platform. The platform was hosted on Amazon Web Services (AWS), which provided scalability and ensured that the platform was accessible to users worldwide.


  • After eight months of collaboration, Artjoker and Lonvest.com successfully created a robust P2P lending platform that includes extensive integration and scalability features.
  • Reduced AWS Costs: Achieved a 30% reduction in monthly AWS expenses within the first six months.
  • Enhanced Infrastructure Efficiency: Improved performance and reliability, supporting scalable growth without proportional increases in costs.
  • Increased Operational Efficiency: Automation and managed services reduced the time spent on infrastructure management, allowing the team to focus on innovation.
  • Adoption of Best Practices: Established a culture of cost-awareness and continuous optimization, aligning with AWS best practices.
