But understanding <em>why</em> things break—like why localhost redirects don't work in production—that's what makes you a real developer, not just an AI prompt writer.</p> <p>Working as a freelancer I built this to land clients. But it's also proof that junior SE roles are within reach if you ship real products and understand your fundamentals even though I haven't found any real clients </p> <p>Next: mobile responsiveness and Python. Always learning.</p> <p>What's your approach to portfolio projects?</p> api javascript softwaredevelopment webdev
