Responsibility:1. Modularized detection engine for decoupling to other modules and increasing the maintainability2. Ported detection engine to a solution platform to enhance performance on data parser and detection rate3. Implemented integrated plug-in reporting module with other teams for the engine, agent, and servers4. Implemented metadata uploading module to deliver data from agents to one server for investigation on server5. Implemented unit test of the metadata uploading module through google mock-up to solid the code quality6. Discussed with other teams to determine the spec and document API development kit of data transformation7. Cooperated with UI/UX designer to design and implement tray icon, tooltips, and UI for SaaS agent using JavaScript and MFC.8. Cooperated with colleagues to develop a new threat detection engine to alter customer of abnormal behaviorAchievements:1. Reduced network bottleneck due to uploading metadata to serve 20,000 clients with single server2. Solved metadata loss and duplication issues to enhance server data validation and computing performance3. Fixed crashes and memory leak by remote debugging and dump analysis to meet the release deadline4. Introduced state pattern design to enrich the scalability of the module and to organize the complicated states of an agent5. Analyzed the metadata, integrated true file type module and the whitelist mechanism to filter 70% metadata to enhance server performance and to reduce data storage size and money spending6. Cooperated with team members to implement the caching mechanism, refactor SQL statements, and adjust SQL setting to improve average CPU usage from 10% to 3%
