Working Experience

Web File Browser System: Developed a tool for browsing files within specified containers in Kubernetes. The system allows users to navigate directories within a container, view text file contents, and download files. File downloads are implemented using streaming, eliminating the need to first download the entire file on the backend before transmitting it to the frontend. The frontend was built using React, while the backend was developed with Spring Boot, employing Mockito for creating mocks and stubs. The entire project was developed using Scrum methodology, with Azure DevOps used for project management and support.
Linux Server Administrator: Responsible for managing Linux servers equipped with public GPUs for the laboratory. Duties included creating and managing user accounts, addressing each user’s specific environment requirements, and utilizing Docker to set up containers. Ensured users could access their dedicated containers using their existing SSH private keys and install necessary libraries. Additionally, used LVM to dynamically expand disk space to accommodate the increasing storage demands as the number of laboratory members grew.
Real-time Fishing Vessel Detection at the Fishing Port: Multiple cameras are installed at the fishing port to obtain the camera images through RTSP and achieve the automated counting of fishing vessels at the port. The backend integrates YOLOv4, FastAPI, and some image processing techniques to recognize the received camera images. The frontend uses Vue as framework to provide detection results and harbor data for the past 48 hours.

Side Projects

RoyKesyShop

This is an online clothing store that uses JWT to verify user permissions. Nginx is responsible for reverse proxying and web serving, while MariaDB is used for replication in a master-slave architecture. Finally, Docker is used to package the above components, along with the frontend and backend, into separate containers.

Roykestereo

This is a cloud-based music player that offers the ability to upload local music, as well as download and listen to music from the cloud. The backend uses Fourier transform and other processing techniques to compute the spectrum of music at each moment. In addition to basic features, there is also a chat room function supported by socket.io, and MongoDB is used for data access.

StellarTrack

This is a web frontend project without a backend, made using Three.js and Bootstrap, displaying the changing paths of the sun’s rotation in different latitudes and regions

WeAreFamily

This is a platform that allows people to find others to crowdfund with. The frontend is mainly composed of JavaFX, while the backend uses Flask as the framework. Users can post to find others to crowdfund with, or join other people’s posts. Users can also send and receive chat messages in real time, with notifications appearing on their operating system.
