About Me

Rina Adibah - Data Analyst

I'm a multidisciplinary professional with a background in Physics and an MBA from SBM ITB, combining business strategy with data analytics to help organizations make smarter, data-informed decisions.

With practical training in Data Science and Machine Learning, I've worked on real-world projects such as customer churn prediction (telecom & e-commerce), housing price prediction, and sales optimization. I've also published academic research using Artificial Neural Networks (ANN), showcasing my ability to apply analytical methods to impactful challenges. I also published a business research project on consumer purchasing intention in live commerce streaming, reflecting my strong foundation in both technical modeling and digital business strategy.

Skilled in Python, SQL, Excel, and proficient in Google Looker Studio and Power BI for building dashboards and delivering data-driven insights. Experienced with Pandas, Scikit-learn, and data visualization techniques to uncover actionable patterns that support business growth. I thrive in collaborative, fast-paced environments that value critical thinking and strategic problem-solving.

I am Google-certified in Data Analytics and Advanced Data Analytics, an AWS Generative AI Graduate, and also hold a Data Science & Machine Learning certification from Purwadhika Digital Technology School, further validating my technical expertise and professional training.

Open to opportunities in data analytics, business analysis, or related fields where I can drive value through data and collaboration.
