• Developed a one-stop office service platform in Java with Spring Boot + MyBatis + Redis and Vue.js for bank employees, where they can track attendance, meetings, tasks, and other things related to daily work. This platform improved their 30% of daily routine work’s efficiency according to surveys by minimizing redundant procedures and paperwork.• Analyzed and visualized platform usage and user preferences data using Python scripts to propose effective optimization suggestions both on performance and functions for the product team.

• Developed a single sign-on and unified user management system with strong security based on face recognition with Vue.js, Java(Spring + Struts2 + Hibernate), Python and MySQL.• Adjusted parameters in MTCNN model, accelerating face detection time under office settings by 20%.• Improved accuracy of face recognition on Asian faces through re-training FaceNet using new data sets.• Built a distributed application cluster using Memcached and Nginx to ensure high concurrency.

•Gained an understanding of the Oracle Analytics solution and plugins through trainings and self-learning.•Assisted in the analytics of business datasets for clients to extract meaningful business information and turn it into intuitional visualizations based on the Oracle Analytics platform and extensions.•Built machine learning predictive models, trained models with sampled datasets, tuned models for better accuracy, and then applied trained models for prediction on the dataset of interest.

•Proposed a trademark image retrieval system that adopted the faster R-CNN (region-based CNN) model to extract global and local features from existing trademark images and compare with that of the queried trademark image by cosine similarity, so as to determine whether the new trademark is too similar to an existing one and accelerate the examination process of new trademark registration.•Used the classified images to train the model, tuned the model, and kept optimizing its accuracy.•Designed and performed experiments to evaluate the new model’s performance and compared it with that of existing ones proposed by other researchers.
