Modified cookware CAD drawings with a senior engineer to validate product quality compliance with specifications and design requirementsConstructed the 3D model of saucepan through SolidWorks. Analyzed mechanical fabrication processes and product engineering of saucepan to extend service life

Developed a unique ID generation service based on the go-micro framework which ensures the user's order number is globally unique∗ Created a database with MySQL which allows the storage, access and invocation of data by the service∗ Designed a unique ID generation algorithm which ensures the uniqueness of the generated ID by inserting the IP address and port number of the container in the ID∗ Completed the design of the incremental sequence, and technically improved the service performance by 10% by allowing the incremental sequence to be generated in advance∗ Reduced the possibility of generated ID duplication by setting a random security codeLaunched the unique ID generation service and completed the service performance test∗ The result of the service QPS test on an 8-core 8G machine is 20000 req/sec

Developed a prototype control system for a civilian quadrotor UAV∗ Constructed mathematical model of quadrotor to calculate attitude and position of UAV∗ Redesigned quadrotor PID control system. Simplified system model and improved the efficiency of system buildingSimulated flight path and attitude of the UAV through MATLAB Simulink and tuned PID parameters to make the UAV achieve a stable flight status
