My first job is a process engineer at TSMC.  To import new chip products, I needed to  communicate with different departments and other fabs. 

After that, I transferred to Cyberbiz, an e-commerce platform, as a back-end engineer. I negotiated with PM and leader about the new function's SPEC and schedule, and cooperated with front-end engineers.

Two years later, I joined Solmate as a senior back-end engineer. I am responsible for the e-commerce checkout page and content management system. For example,  administrator establishment, order management, logistics management, merchandise control, marketing activities, third-party API connection, shopping cart Checkout page and checkout verification. 

This year, I served as a TA in a blockchain camp to research smart contracts.
