About Me

With over a decade of experience across sales, education, and administration, I've consistently leveraged data to drive better outcomes. Whether optimizing sales strategies at Vodafone, tailoring educational approaches as a private tutor, or improving operational efficiency in administrative roles, I've always sought to uncover the story behind the numbers.

My journey has led me to formalize this passion through a Diploma in Data Analytics & Business Intelligence. This training has equipped me with advanced skills in statistical modeling, data visualization, and business intelligence tools - allowing me to transform raw data into strategic assets that inform decision-making at all levels.

What excites me most about this field is the opportunity to bridge the gap between technical analysis and business strategy. I thrive on translating complex data into clear, actionable insights that drive growth, improve customer experiences, and optimize operations.
