    Full Stack Developer
    März 2018 - Dezember 2021 (3 Jahre und 9 Monate)
    As a Full Stack Developer with AI integration experience, I am proficient in a variety of languages and frameworks, including Python, Django, Flask, React.js, Node.js, Express.js, Next.js, and Nuxt.js. I have the ability to build and scale full-stack web applications and also integrate AI-powered features such as recommendation systems, chatbots, and predictive analytics.

    On the back end, I am skilled in Python and have experience with both Django and Flask. Django is a high-level web framework that comes with many built-in features, which accelerates development. It supports integration with AI and machine learning models using libraries like TensorFlow, PyTorch, and scikit-learn, enabling me to build intelligent web applications. This is particularly helpful when developing websites that need common features like admin interfaces, user authentication, database connections, and AI-based automation.
