As a senior full-stack engineer, I have extensive experience working with AWS, AppSync, Vuejs, Nuxt, SSR, and ElasticSearch. I have been working on a complex social media AI product that enables users to share videos and analyze their contents. I have been responsible for several key contributions to the product, including integrating Elastic Search to dramatically improve performance and implementing key features that have driven the product's growth. I have been a key player in the development of this product, working closely with the team to deliver a cutting-edge, high-performing solution for the social media industry."
