Is it Possible to Learn App Development Alone in 6 Months?

I've recently teamed up with three co-founders to start a small business. Each of us has our own role: one is focused on marketing and design, another on business operations, and I'm responsible for developing our app. I'm quite familiar with AI and can craft good prompts, but I want to do more than just rely on AI to build the entire product. I've put together a list of tools and technologies I plan to learn. I already know Python, JavaScript, and the basics of PHP and SQLite, and I have some experience with Git and GitHub. However, I'm green when it comes to frameworks or libraries—especially React and React Native—and I've never set up continuous integration or continuous deployment (CI/CD). I'm determined to learn and have set aside around six months to develop the app, using AI to assist me. My main concern is whether it's realistic to accomplish all of this in that timeframe while managing all the development work solo until we can hire more developers.
