Skills
- 1 Proficient in multiple programming languages including Python, Golang, and Java, with a strong ability to develop complex software solutions and OOP Programming
- 2 Experienced in machine learning applications engineering (Recommendation System, AIGC Image Generation), leveraging ML tools (PyTorch, Tensorflow) to integrate AI technologies into software projects
- 3 Skilled in software design and development, with a solid understanding of Linux Shell scripting and the use of Docker for containerization and CI/CD deployment processes
- 4 Adept at using middleware for application development including MySQL, Redis, Kafka, Nacos
- 5 Proficient in version control with Git, JIRA and fluent in English, ensuring effective collaboration within diverse and global development teams
- 6 Experienced with various NVIDIA GPU architectures and technologies, including GPU Direct Storage, NVLink, and NVSwitch
PROJECT EXPERIENCE
- GPU Cluster Scheduler: By utilizing middleware for service registration and discovery, the AIGC image generation service was deployed to different clusters with eight 4090 GPUs, and a cache model tag was registered for each GPU for the upstream scheduler service to make image generation requests. This reduces the switching and loading of different style models on the same GPU, thereby increasing the efficiency of image generation and reducing the model loading time by approximately 18.7%.
- Weibo Hot Search Recommender System: Hot Search Recommendation System Development (QPS 800 - 10000) Stability maintenance and development of the hot search recommendation list service based on the Python 3.8 Sanic framework, participation in the upgrade and refactoring of the original Python 2.7 service, and upgrading through the new framework. The main goal was to address the low I/O utilization and weak concurrency performance issues of the old Python 2 framework. The project supported the development of daily business strategies, reduced the interface timeout rate by more than double, and increased the QPS of a single machine by more than double.
