This workflow framework can dynamically execute different sets of codes in real time with no additional code changes and compilation. For example, the process can be dynamically changed at task 3 to skip task 4 to task 9 and execute task 10 to task 20 by simply changing the next tasks in the database table while the process is running.• Learn by working on humanoid, exoskeleton, and drone robots driven by artificial intelligence such as Tensor Flow, SLAM, ROS 2 as a side project in my spare time.• Interested in a technically challenging environment to explore and apply new technologies to increase business productivity.
