Work Experience

Auto Triage Code Generator: Developed an LLM-powered agent with LangChain enabling non-expert users to identify and triage algorithm issues, reducing debugging time by over 50%.
K8s Cluster Migration: Unified ADC and master environments, consolidated build/upload/deployment scripts, and ensured continuous cluster availability with zero downtime.
No-Comms Pipeline: Designed a lightweight intra-process messaging mechanism to bypass shared queues, improving memory efficiency by 65.45\% and enhancing system responsiveness.
Routing Server & SVG Movement Preview: Built a C++ routing server generating timestamped tracking points and kinematic data, enabling frontend visualization of vehicle movement via SVG with velocity and acceleration charts, improving scenario designing efficiency by over 80%.

Permission Control System: Designed a hierarchical permission control system with a tree structure.
Dual Video Player: Developed a dual video player to synchronize and compare mbag data at specified timestamps, allowing the perception team to compare simulation results with original data.
PointCloud Renderer: Integrated OpenCV colormaps into the PointCloud renderer, enhancing 3D model visualization with improved sensitivity to subtle intensity variations.
Interactive 3D Contour & Marker System: Developed a user interaction system with contour highlights, custom context menus, and distinct click handlers for enhancing 3D shape visualization and interaction.
State Management Enhancement

Enhanced Redeemer Extension: Troubleshot over 10 bugs and developed more than 20 new features for Redeemer, a browser extension that helps users view price changes and discount information while shopping online.
Contributed to UI/UX design reviews: Updated user interfaces in Figma, ensuring seamless integration of design interfaces into effective React components.
Designed and implemented an automation test framework: Leveraged Puppeteer to evaluate CSS selectors and test functionalities across approximately 40 e-commerce websites, improving test speed by more than 10 times compared to manual testing.

Integrated Label Studio for Data Annotation: Translated, migrated, and implemented the Label Studio open source data labeling platform into the company’s service, significantly enhancing data annotation capabilities.
Developed SSO Authentication Module: Created a robust Single Sign-On (SSO) authentication module in Django, streamlining user management and security, and improving login speed by 66% on average.
Implemented User Hierarchy System: Developed a system to differentiate permissions between general users and admin users, improving overall security and user management.
