Designed and developed several microservices for a logistics system with a complete business loop, enhancing task scheduling, real-time order tracking, and intelligent route management using Spring Boot and Spring Cloud. Designed and implemented a base microservice to handle all RabbitMQ operations, integrated delayed message processing for order management to guarantee transaction completion, and facilitated asynchronous communication between microservices for route management. Developed and implemented over 10 RESTful APIs using Spring Boot to support CRUD operations for various databases, including MongoDB, MySQL, and Elasticsearch. Utilized pagination to manage large datasets and asynchronous processing to enhance performance. Implemented MongoDB 2dsphere indexing for efficient storage and querying of geospatial data related to delivery personnel and warehouse service areas. Integrated MySQL for transactional data, customer information, and payment records; used Neo4j for managing transportation nodes and routes. Applied Elasticsearch indexing to delivery tasks, enabling efficient full-text search and filtering. Enhanced search capabilities with custom analyzers and tokenizers, improving search performance through partial matches and synonyms. Improved CI/CD pipeline configuration in Jenkins to code, verify, and build a new website, facilitating a successful parallel launch to production. Containerized the microservices with Docker and deploy with Kubernetes
