Python developer with a strong foundation in medicine and pharmaceuticals, bringing analytical
skills from healthcare to coding. My experience spans web development (Python, Django, HTML, CSS,
JavaScript), automation (Python scripting, Selenium), and data analysis (Pandas, NumPy, SQL). I have
a proven ability to work effectively in international, cross-functional teams and am committed to delivering
high-quality software solutions. My GitHub hosts several projects where I applied best practices, such as
writing clean, maintainable code, rigorous testing, and agile methodologies. I’m eager to combine my
technical skills and healthcare expertise in a collaborative, dynamic environment.
