## Productionize machine learning projects∗ Implemented an SQS service and gRPC services for grouping emails with similar structures and extracting usersensitive data to increase the amount of training data without violating customer privacy regulation.∗ Designed and Implemented a two-stage labeling system that automatically communicates between AmazonMechanical Turk and in-house experts to generate high-quality labeled data and enhance merchandisetaxonomy to increase customer conversion rate.∗ Migrated and automated the deployment process of AWS Lambda procedures that process customer lifetimevalue, reducing the effort of maintenance and deployment.## Build and maintain data pipelines on Apache Airflow∗ Implemented a pipeline that processes data larger than 10 GB to infer personalized preferences to help increasecustomer satisfaction.∗ Migrated legacy 1.x Airflow server on AWS EC2 to 2.0.2 Airflow on AWS MWAA, saving developers’ effort ondealing with legacy dependencies issues, and created a development airflow environment for doing experimentswithout affecting the production pipeline.∗ Refactored data writing mechanism and reduced the data write time and AWS S3 cost.∗ Built alerts and dashboards to monitor pipelines metrics to minimize the effort of troubleshooting usingDataDog, Prometheus, and Kibana.## Standardize and maintain software engineering practices∗ Created and maintain the project templates, with automatic code quality check, testing, containerization,project versioning, releasing and deployment, and a standard workflow for existing projects to update tools,which reduced project creation time, the communication overhead during code review and provided an easyway for developers to introduce new standards.## Optimized SQL in a data pipeline and reduced the execution time from infeasible to within half a day

* Containerized and fixed legacy projects in "The Mosquito Man"* Introduced code review culture to a newly formed team* Set up a "drone" CI/CD server and created CI pipelines for two ongoing projects

Tainan City, Taiwan

* Managed the executive team with 16 members* Reviewed the teaching proposal of Python course, "Programming Design Foundation"* Designed exercises for "Data Structure," the first section of "Computer Science Foundations"* Lectured "Web Programming, Database/Cloud Computing," the fourth section of "Computer Science Foundations"X-Village is an experimental education program aiming to equip students not major in computer science with the ability of computational thinking and to enhance future cooperation between computer science and other areas. I was the executor of the program and the leader of the teaching assistant team. Besides, I designed a half day exercise for Data Structure and lectured a four-hour web backend course for Web Programming, Database/Cloud Computing.
