Cybersecurity Engineer Intern (Analytics & Visualization with AI) @ GovTech Singapore
About
I am a passionate and driven individual with a diploma in Business Intelligence and Analytics (graduated with merit) and currently in my final year pursuing a Bachelor’s degree in Computer Science, majoring in Cybersecurity with a track in Business Analytics. My journey into IT began during my time at Polytechnic, where I discovered a deep interest in cybersecurity. What excites me the most is understanding how theoretical concepts in cybersecurity and analytics can be applied to solve real-world challenges and enhance organizational security frameworks. With a strong foundation in analytics and a growing expertise in cybersecurity, I aim to bridge the gap between data-driven insights and secure IT practices. I’m eager to learn, collaborate, and contribute to the dynamic field of cybersecurity and business analytics, exploring innovative ways to address emerging threats while optimizing decision-making processes.
