Work History
Technical Expert
Alibaba Group
Chengdu, China
03.2018 - Current
- Implemented a serverless runtime solution by C++ to support python/java/rust development and deployment. The design of this runtime is component-based which can easily add more functional code with low coupling code. As a result, data scientists can use, for example, python runtime to build training or inferencing processes that can quickly deploy to the production environment with no concern about stability issues.
- Built an event-driven task manager that can schedule arbitrary jobs to run on the Kubernetes cloud. Jobs can be orchestrated in DAG(directed acyclic graph)form, and each job node can run in single mode or parallelism mode. In the latter situation, one can do distributed tasks. The whole system is designed with a primary-secondary pattern that can stand the crash of either node.
- Worked with data scientists to normalize the ML model development process, including standardizing the dataset format, abstracting different repeatable ML tasks, building automated training pipelines, etc. The whole process can save the data scientists from doing the repeated job and focusing on innovative ideas.
