Accelerating Mobile Credit Platform: A 3-Month Blitz for Performance and Cost Efficiency

User Account Management
The platform will provide seamless user registration and onboarding, enabling users to sign up using their mobile numbers or email addresses while completing identity verification (KYC) and credit eligibility checks. A centralized dashboard will allow users to view their credit balances, transaction history, credit scores, and repayment schedules. Users can also manage their profiles by updating personal details, linking bank accounts, and setting preferences.

Credit Scoring and Loan Processing
The platform will feature automated credit scoring, leveraging advanced algorithms to assess user eligibility based on financial data, transaction history, and alternative metrics. It will streamline the loan application process, enabling instant approvals based on predefined rules and AI-based decision-making. Additionally, the system will dynamically adjust credit limits in real-time, reflecting users’ repayment behavior and updated credit scores.

Payments and Transactions
Payment gateway integration will support various payment methods, including bank transfers, mobile wallets, and card payments. The system will also offer repayment management tools such as scheduled auto-debit, payment reminders, and flexible repayment options. To ensure transaction security, encryption and tokenization mechanisms will be implemented.

Notifications and Alerts
The platform will deliver personalized notifications, keeping users informed about due payments, credit limit updates, promotional offers, and account activities. These notifications will be sent through multiple channels, including SMS, email, and in-app messages, ensuring timely communication.

Analytics and Insights
Comprehensive analytics tools will provide insights into user behavior, repayment patterns, and credit utilization. The platform will also include credit risk analysis features to identify and mitigate potential defaulters using predictive analytics. Performance metrics dashboards will track key business indicators such as loan disbursement rates, repayment success, and operational costs.

AWS Cost Optimization Features
The platform will use AWS auto-scaling services to dynamically adjust compute resources based on demand, ensuring cost efficiency. It will optimize infrastructure for predictable workloads by employing a mix of on-demand and reserved instances. Data storage management strategies, such as lifecycle policies for archiving or deleting unused data in S3 buckets, will be implemented. Additionally, AWS CloudWatch will provide real-time performance and cost analysis, while specific workloads will be transitioned to server less architecture with AWS Lambda to reduce overhead costs.

Scalability and Performance Enhancements
To enhance scalability and performance, the platform will utilize an API Gateway for secure and scalable communication between mobile apps and backend systems. Caching solutions like Redis or Memcached will be employed to improve data access speeds and reduce database loads. The database will be optimized with fine-tuned queries, indexing, and managed services like Amazon Aurora or DynamoDB.
