Uniscan

Uniscan is a full-stack web application that enables users to explore Ethereum wallet transactions efficiently. The application processes historical transaction data through a distributed queue system, providing real-time updates and optimized query performance.

Key Features and Technical Achievements:

• Architected a scalable backend using NestJS, Prisma, and PostgreSQL to handle high transaction throughput
• Implemented distributed job processing with Redis and BullMQ for efficient historical transaction batch processing
• Built a responsive frontend using Vite, React Query, and Tailwind CSS with optimized data fetching and caching
• Developed comprehensive test coverage including unit tests and end-to-end tests
• Set up CI/CD pipeline using GitHub Actions for automated testing and deployment
• Containerized the entire application stack using Docker Compose for both development and production environments

The application features a robust architecture that separates concerns between the frontend and backend:

Backend Stack:

• NestJS for the API framework
• Prisma as the ORM
• PostgreSQL for data persistence
• Redis for caching and queue management
• BullMQ for distributed job processing

Frontend Stack:

• Vite as the build tool
• React Query for efficient data fetching
• Tailwind CSS for styling
