Hello, I’m Zola.

I am deeply passionate about transforming data into valuable insights, fueling data-driven decisions that drive real business impact.

My Story

I’m a lifelong explorer who is driven by curiosity, growth, and a desire to take on new challenges. I value balance, empathy, perseverance and strive to reflect these values in both my personal and professional life.

My journey began in marketing, where I quickly learned that creativity alone wasn’t enough. In a world of tight budgets and high stakes, I relied heavily on data through market research, surveys, and analysis to craft strategies that could stand up to scrutiny. The process of uncovering insights and making sense of patterns in numbers sparked something in me. I found joy in data analysis, as it gave meaning to the decisions I made and allowed me to tell compelling, evidence-based stories.

That joy evolved into a deeper passion and led me to pursue a Master of Business Analytics at Macquarie University. As I continue to expand my knowledge, I see more clearly how data and information systems empower better decision-making, create business value, and contribute to broader impact.

Database
design & query

Designed and implemented a relational database for Pro App by identifying key entities and their relationships, creating an ER diagram, and writing SQL queries to address business questions, generating insights to improve operations and customer satisfaction.

Big data

I successfully completed a big data project where I applied efficient data extraction and processing techniques using MongoDB, pymongo, and MapReduce. By extracting only the necessary data from a large dataset of song documents, I was able to significantly reduce computation time and costs.

Bank client behavior prediction

The goal of this analysis is to compare the performance of two machine learning models, Logistic Regression and Random Forest, in predicting whether a client will have overdue payments. By using features from client application and credit records, the analysis aims to assess which model can better predict a client's likelihood of having overdue payments, based on accuracy metrics.
