In today’s rapidly evolving business landscape, where data drives decision-making, organizations must harness the power of data to stay competitive, grow, and optimize their performance.
One individual who has consistently demonstrated mastery in this arena is Adetumi Adewumi, a seasoned business and data analyst whose innovative approach to financial modeling and operational efficiency has transformed industries and redefined success.
With over five years of hands-on experience, Adetumi has established herself as a data-driven visionary, revolutionizing how companies leverage analytics to boost profitability and streamline processes. Adetumi’s journey into the world of analytics began with a strong academic foundation, where her love for numbers and keen analytical skills first took shape. She earned a Bachelor of Science in Accounting from Covenant University in Nigeria, where she honed her ability to dissect complex financial data.
However, Adetumi’s ambitions extended far beyond accounting, she sought to revolutionize how businesses made decisions by transforming raw data into actionable insights. Her pursuit of deeper knowledge led her to the University of Illinois at Chicago, where she obtained two Master’s degrees: one in Business Analytics and the other in Management Information Systems. During her studies, she mastered advanced data mining, machine learning, statistical analysis, database management, and data visualization, equipping her with the skills to navigate the complex data landscapes that modern businesses encounter today.
Adetumi’s technical skills span Python, SQL, Tableau, Excel, and more, enabling her to transform large datasets into meaningful insights that drive decision-making and strategic planning. Her aptitude for project management and her ability to collaborate effectively with cross-functional teams has been instrumental in her success as a data-driven leader.
In May 2024, Adetumi joined Intello Group Inc. as a Data/Business Analyst, where she quickly proved her value. Faced with the challenge of evaluating the company’s financial performance and improving forecasting accuracy, Adetumi developed sophisticated financial models that incorporated revenue projections, cost analyses, and sensitivity variables.
These models didn’t just crunch numbers; they told a story that helped the leadership of the organization understand the potential outcomes of strategic decisions. Thanks to her efforts, Intello Group saw a 15% improvement in forecasting accuracy, which led to more informed and successful investment decisions. Adetumi’s impact at Intello Group wasn’t limited to financial forecasting. She revolutionized the company’s data management practices by employing advanced SQL and Python techniques to streamline the data collection, processing, and analysis process.
This automation reduced data processing time and enhanced the accuracy of datasets, resulting in a 12% increase in operational efficiency and a 5% reduction in costs. These achievements directly contributed to improved profitability, making her an invaluable asset to the company. One of Adetumi’s most significant accomplishments at Intello Group was the creation of key performance indicators (KPIs) and benchmarks to monitor financial and operational performance in real-time. She implemented dynamic dashboards that provided leadership with the data-driven insights they needed to make faster and more accurate decisions.
Her work transformed how the company approached business analytics, positioning Intello Group as a leader in its sector. Before her success at Intello Group, Adetumi made waves at JPMorgan Chase, one of the world’s largest financial institutions. As a Data Analytics and Automation Specialist, she was tasked with driving efficiency and automation within the firm. Recognizing the time-consuming nature of traditional data reporting methods, Adetumi leveraged her technical skills to automate the extraction and compilation of data from multiple sources, reducing report generation times by 50%. At JPMorgan Chase, Adetumi didn’t just drive efficiency, she fundamentally transformed how the company tracked performance metrics and made decisions.
She designed and implemented advanced Tableau dashboards that provided real-time insights into key performance indicators, giving leadership the ability to act quickly and with greater precision. Her expertise in exploratory data analysis using SQL allowed her to uncover hidden trends within large datasets, resulting in strategic recommendations that boosted operational efficiency by 40%. In one particularly innovative project, Adetumi used machine learning techniques to enhance diversity, equity, and inclusion (DEI) compliance. She trained a natural language processing (NLP) model using Python’s Spacy package to automatically identify non-inclusive language in company documentation, ensuring 100% compliance with DEI standards. This innovation saved the company significant time and resources by eliminating the need for manual document reviews and highlighted Adetumi’s commitment to both technical excellence and corporate social responsibility.

At the Transmission Company of Nigeria, where she served as a Data Analyst, Adetumi applied her expertise in data analysis to customer data, identifying key trends that led to a 15% increase in customer retention. By developing targeted communication strategies and personalizing customer engagement through insights derived from random forest models and hypothesis testing, Adetumi demonstrated her ability to combine data science with marketing and customer relationship management. Additionally, Adetumi played a pivotal role in optimizing the company’s marketing campaigns by developing A/B testing frameworks that informed data-driven decisions.
These frameworks helped the company boost customer engagement by 20% and enabled leadership to make more informed decisions about product offerings and communication strategies. Her ability to lead and mentor junior analysts further enhanced the company’s data-driven culture, solidifying her impact on the organization. Adetumi’s proven ability to transform businesses through data-driven insights, innovative financial models, and operational efficiency improvements has positioned her as a visionary leader in the field of business analytics.
