Simmon Shen

I am a dedicated back-end developer with a strong foundation in Java and extensive experience in optimizing database performance. My journey began at Shanghai Jiao Tong University, where I successfully built a 3D globe tile map using Cesium, integrating satellite trajectory visualization to enhance user understanding of satellite dynamics. I also migrated a MySQL database to PostgreSQL, ensuring data consistency and integrity while improving performance.

At the Bank of Communications, I further honed my skills by conducting deep optimizations of system interfaces, significantly reducing query times from 5 seconds to just 20 milliseconds. I implemented a large data packet locating function based on ElasticSearch, integrated with SpringBoot, which improved query efficiency for daily processing of millions of data points. My work on developing a performance indicator monitoring tool using InfluxDB allowed for real-time transaction analysis, enhancing system maintenance efficiency.
