    Frontend Developer

    Falkonet

    Entered the company with no prior knowledge of React but quickly upskilled through self-learning and project involvement. Solved a major performance issue by implementing Redux to optimize state management, reducing unnecessary re-renders and improving app speed by 30%. Technologies used: JavaScript/TypeScript, React.js, and Tailwind CSS. These experiences served as the foundation of my tech career, blending my passion for coding with a hands-on approach to problem-solving.

    Frontend Developer Trainee

    Kreativstorm GmbH

    Collaborated in multi-developer teams where maintaining code consistency and development speed was challenging. Applied best practices, including modular design, reusable components, and comprehensive documentation, to streamline contributions. This approach led to cleaner, more maintainable code, boosted team productivity, and significantly reduced debugging time.

    Internship (SASS, JavaScript)

    Starlabs

    Built a Real-Word project where I encountered inefficient DOM manipulation with JavaScript, leading to slow page rendering and poor user interaction. I optimized the code by reducing DOM access and implementing event delegation to handle user interactions more efficiently. This improved page load speed and responsiveness, significantly enhancing user experience and reducing performance-related issues. Collaborated within a team environment, gaining experience in version control with Git and GitHub.
