Enhanced IoT SIM Card Management Console
• Spearheaded the optimization of the IoT SIM Card Management Console by implementing microservices using the Spring Boot and MyBatis framework. This streamlined the process for managing SIM cards, resulting in a staggering 500,000 new SIM card purchases
• Employed an efficient RPC framework to facilitate seamless communication with other services, ensuring smooth interoperability across the ecosystem
Efficient Middleware
• Orchestrated the integration of SchedulerX as a task scheduling middleware, enabling dynamic task splitting and aggregation for batch operations involving SIM cards
• Implemented message queue middleware and CompletableFuture class to enable multi-threaded, asynchronous processing capabilities to handle concurrent SIM card operations, optimizing system throughput to tens of millions
• Leveraged Redis caching to offload data from MySQL, significantly reducing network latency and enhancing overall system performance. Implemented Master-Replica configuration for MySQL, enabling read-write separation and ensuring high availability and fault tolerance of the database
Ground-Up Construction of IoT SIM Card Hosting Platform
• Played a pivotal role in architecting and developing an IoT SIM card hosting platform from scratch
• Designed and deployed a scalable platform capable of managing hundreds of millions of SIM cards with precision and efficiency
• Achieved remarkable results by driving the platform's revenue to $2,000,000 within just one month of its launch, showcasing its rapid market adoption and commercial success
