As Software Developer at a start-up company (latest eFishery), I have experienced build web-based applications such as e-commerce, web forms, a dashboard to monitoring machines with real-time data or systems for the internal company. And also currently I developed a PWA to help employees (field technical support) in my company to report their activities. These applications built with JS stacks such Angular, React.JS, Node.JS, and cloud computing services such as Firebase and AWS (AWS Amplify, AWS SAM)
