With my comprehensive skills in Full Stack Web Development and proficiency with React and Node, I believe I am the best fit for your project. Not only have I successfully completed over 50 freelance projects, but I have also deployed numerous web apps to various servers, including Linux-based ones. My ability to understand different technological ecosystems and troubleshoot issues would ensure a seamless deployment and functionality check for your app.
Furthermore, as an AI and Automation expert, I bring to the table an extra level of problem-solving prowess. My experience in data analysis, data mining, and API's can be particularly valuable during system checks as they involve collecting valuable insights about the app's performance, finding bottlenecks if any, and optimizing experience through automated processes.
Rest assured that I am dedicated to delivering results that not just meet your expectations, but exceed them. Allow me to demonstrate my competence with a successful deployment and hitch-free function of your web application on your Linux server alongside my full commitment to ensuring timely completion of the project.
