Summary
I completed my studies in Mathematics, where I developed a strong passion for problem-solving and analytical thinking. I particularly enjoy the challenge of transforming raw datasets into clean, structured forms and uncovering meaningful insights from them. During my academic years, I worked on several statistical projects using R, SPSS, and Python. Currently, I am attending two Data Analytics Bootcamps to further expand my knowledge and practical experience. I am a quick learner, highly motivated, and eager to collaborate with diverse teams.
