At Guangzhou Dingxin Yun Technology, I worked on heroVoice, a multilingual voice platform for users in the Middle East. I replaced local Quartz scheduling with sharded XXL-JOB processing for主播 weekly settlements, reducing processing time from about three minutes to around 40 seconds.
I also improved the platform’s operations and finance workflows. I moved bulk message delivery to asynchronous processing, added Redisson distributed locking to protect withdrawals, and used streaming Excel exports to reduce the risk of memory errors.
At Shenzhen Dingyou Information Technology Co., Ltd., I worked on a tourism product management platform built with Spring Cloud Alibaba. I contributed to service integration and parallel inventory allocation, and designed channel-specific notification handlers for order updates across OTA platforms.
Earlier, at Shenzhen Moqi Culture Guangzhou Branch, I contributed to the Nila voice-chat platform, including music-library features and activity modules using Redis and Lua. I also implemented an MP3 upload interface with file validation and Qiniu Cloud upload tokens.
