Experience

    Full Stack Web Developer
    SOFTWARE PUBLISHING
    January 2024 - Today (2 years and 7 months)
    I support companies in developing custom web applications, from the initial idea to live operation. My focus is on Symfony/PHP in the backend and React/Next.js in the frontend, complemented by modern UI frameworks (Tailwind, Chakra UI).

    My projects include, among others, business web apps, configurators, learning platforms, and SaaS solutions. I handle technical conception, implementation, and integration of external interfaces (e.g., import/export, APIs) as well as optimizations in performance, code quality, and deployment processes.

    Through my experience in full-stack development, data management, and UX-oriented design, I offer clients a holistic solution from a single source, including hosting if necessary.
