Aspiring Data Analyst passionate about transforming raw data into actionable insights. Building real-world analytics projects using Python, SQL, Power BI, Excel, Machine Learning, and interactive dashboards while continuously exploring modern data technologies.

01. About Me

Who I Am

A curious mind driven by the desire to uncover stories hidden in data

My Journey

I'm an aspiring Data Analyst and technology enthusiast who enjoys transforming complex datasets into meaningful insights and practical solutions.

My journey began during engineering, where curiosity led me to explore software development, artificial intelligence, and research. Along the way, I built my own Personal AI Assistant, an experience that strengthened my problem-solving mindset and passion for innovation.

Everything changed when I was introduced to Database Management Systems (DBMS) and Oracle SQL. Learning how data is stored, queried, and transformed sparked a genuine interest in analytics. Since then, I've been focused on mastering Python, SQL, Excel, Power BI, Machine Learning, statistics, and data visualization through hands-on projects and continuous learning.

Today, I'm building real-world analytics projects, documenting my learning journey, exploring the intersection of Data & AI, and preparing to create meaningful business impact through data-driven decision-making.
