Building risk engine. integrating Apache iceberg with our current data service.

• Developed a Mini program, using Java, Hive, and SQL, which can generate SQL queries automatically from several instructions and call requests using OpenAPI on our visualization platform to show the results.• Refactored the code with concurrent design in our module by better scheduling the subtasks, and Developed a robust event tracking system to report every state changes of each subtask, which allow us to monitor the fluctuation of event data, such as subtask success rate and the rate of different error codes.• Developed an applet with Golang and CLI framework, optimizing the MR workflow of minor commits, such as version update modification.• Updated the uploading SDK to the new version changing a lot of APIs, and maintaining the related code.• Solved historical bugs avoiding App crashes during slice-by-slice uploading on Douyin and TikTok.• Developed daily requirements from PMs to ensure the stable iteration of the module.• Collaborated with PMs and engineers of the development platform to suggest new features to make thedevelopment routine more smooth, and also follow up on the process.
