• Responsible for ensuring the Li-ion Battery Energy Storage System (BESS) passes acceptance tests, handling after-sales troubleshooting, supervising vendors' work orders, providing design feedback, and facilitating communication between customers and CLOU HQ• Led the vendor and CLOU teams in remediating the fire suppressant release incident of the BESS to meet customer requirements and expectations• Drafted five standard operating procedures (SOPs) for parameter migration of control modules, E-Stop swapping, functional testing of the fire manual pull station, battery array insulation testing, and fire suppression system testing• Utilized the system electrical schematic and developed a systematic debugging approach to resolve issues with the humidity/temperature sensor going offline, the auxiliary power switch tripping after firmware flashing, and the control console going offline• Scripted an automatic data retrieval Python program, enabling technicians to download multiple control modules’ data in batch within ten minutes

• Diagnosed the customer devices using Altium designer and multimeter to successfully pinpoint the failure components• Calibrated the device using Arbin Mits Pro to adjust the current and voltage controls within 0.02% error• Developed a new testing scripts and procedures to improve the machine testing counts from 2 to 6 per week• Assisted a colleague to verify the supercapacitor array PCB design and provided two corrections in the design schematic• Simulated the voltage protection circuit with LTSpice to improve the understanding of the product operation

• Developed a web server to allow different teams to manipulate sensor data from 3D printers in the cloud platform• Corporated with the Machine Learning team to establish the simple demo of the Edge-to-Cloud concept• Launched the web service using Go programming language on AWS EC2 to successfully upload and retrieve sensor data• Implemented AWS DocumentDB database to ensure the large packet of sensor data can be uploaded at once• Implemented a new database structure to significantly reduce the query time from 2 minutes to 30 ms• Developed a multiprocess RTOS program for ESP32 microcontroller to ensure real-time sensor data can be uploaded via REST API

•Developed the 2019 - 2020 vehicle electrical harness by Siemens Nx12.0 to ensure data collection and power supply•Provided supervision for new members to assure the proper connections between sensors and connectors in the harness of 2019-2020 vehicle•Designed the electrical component box to place the motor controller for the gear-shifting purpose by SOLIDWORKS •Designed the integrated PCB board for powering the shifting controller and receiving CAN data by Autodesk Eagle

• Rearranged the prefabricated house production line to fit into the 400m * 48m manufacturing plant by AutoCAD• Modified the Siemens S7-400 PLC program with the chief engineer to increase beer boxes stacks’ layers from 6 to 7 for Anheuser-Busch InBev (Budweiser) bottle recycling line • Designed the steel reinforcement bar feeder for reinforcement cage welding of the concrete pole by SOLIDWORKS• Generated the new production line for automation concrete pole manufacturing by AutoCAD
