- GamePlatform Team
(Full time) - Developed custom internal tools to enhance operational efficiency and streamline testing processes
- Implemented a monitoring and alerting system to quickly detect and share errors during the software build and deployment process, collaborating with QA and developers to improve work processes and productivity
- Maintained Jenkins CI/CD pipelines, focusing on resolving underlying issues to prevent recurrence of problems instead of merely responding to them
- Standardized the build system by:
- Consolidating version control tools from Perforce, SVN, and GitLab to GitLab
- Unifying build scripts from shell, Python, and Groovy to Groovy
- Centralizing build tools to Jenkins
- Constructed a monitoring and alerting system to collect critical error occurrence information from the engine (using C++, ELK, and Slack)

(Internship) - Python Crawler Optimization:
- Optimized a Python crawler that initially relied entirely on Selenium, resulting in slow performance and frequent failures (over 50% error rate) without any error handling or notifications
- Refactored parts of the crawler using Scrapy to improve speed and implemented an alerting system
- Enhanced data collection methods and timing by incorporating server maintenance information and server-provided data
- Reduced collection time by over 80%, from 3 hours to under 30 minutes
- Automation of Manual Data Entry:
- Automated the manual entry of version information files, which was a repetitive task prone to errors due to its high volume
- Decreased the time required for this task from over an hour to less than 10 minutes, significantly improving efficiency and requiring only a final review
- News Crawler and Report Generation:
- Managed a news crawler that collected 100-200 news articles daily
- Automated the process of filtering news related to the team's products by:
- Collecting frequently used keywords from the titles of previously accumulated product-related news (updated periodically using a script)
- Generating reports based on these keywords, eliminating the need for manual separation of relevant news
