Developed efficient CI/CD pipelines that automated package publishing and significantly accelerated the release cycle. Created internal UI libraries used across more than 30 internal projects, improving interface consistency and reducing development time for new components. Optimized large data lists, reducing load time from 30 seconds to 500 ms. Accelerated hot reload from 4 seconds to 1 second by implementing concurrent mode and parallelized development processes.

Independently developed a full-featured Electron desktop application with dynamic proxy assignment for each manager and real-time state synchronization across multiple renderer processes. Built an admin panel using Next.js with real-time data charts, large interactive tables, an integrated chat, and step-by-step product walkthroughs. Configured automated CI/CD pipelines, implemented build scripts for development and production environments, and added automatic update functionality. Created a reusable internal UI component library and a Chrome extension with dynamic proxy switching. Developed a custom solution to bypass Google CAPTCHA using a headless browser: Puppeteer ran on a remote server, real-time screenshots were streamed to the client via WebSocket, and user click coordinates were sent back to Puppeteer to simulate real interactions.
