      • Developed on the server side of a cross-platform mobile app based on Golang, later the app became part of OpenLanguage, currently having over 1 million downloads. • Completed features including batch modification, insertion, query word frequency. • Increased word attribute query efficiency by 100% using coroutines to split the large RPC call, and ensured data consistency with distributed locks. • Speeded up the word searching module by adapting it for batching query and calling Redis with pipelines for caching query results. • Guaranteed the consistency of the master-slave database by avoiding immediate queries to the slaves after writing into the master. • Developed the feature to remind all study group members with one-click, and resolved bugs caused by anonymous functions of coroutine calls witch use parameters from the main thread in the process. • Implemented word search result sorting feature by using string segmentation to handle words and phrases. • Utilized MySQL indexes to speed up user data querying.
