Built the system on a microservice architecture.
Split application into modules with lazy loading for better performance.
Optimized code, restructured components and database, and applied best practices.
Used Redis cache cluster to accelerate read operations.
Integrated RabbitMQ to improve write-side performance.
Researched and configured Amazon Cloud services, Coin services, and Bitcoin network.
Managed tasks, sprints, and deadlines using the SCRUM model and YouTrack.
Applied Memcache + Redis for short-term caching (2s) with background jobs to process data asynchronously.
Integrated services that operate effectively in regions with restricted access (e.g., China).
