From her Data Science studies at Stellenbosch University (SU) to her current role in global markets at the Standard Bank Group, Tiara Pillay’s journey has been shaped by curiosity, adaptability and a passion for using data to solve real-world problems.

It all began with a Bachelor of Data Science in Statistical Learning which Tiara completed in 2024. She was drawn to the field, because of its unique blend of statistics, programming and real-world decision-making.

“I found it fascinating that you can use data not only to understand what has happened, but also to predict what might happen next and help organisations make better decisions,” she says.

She describes SU’s Data Science programme as well-structured and well-rounded.

“The degree gave me a strong foundation in statistics, mathematics, computer science and machine learning, while also emphasising practical application. That balance prepared me well for the workplace, because it taught me not only the technical concepts, but also how to think critically and solve real-world problems using data.”

After graduating, Tiara joined the Standard Bank Group as a data science graduate in its Data Science Mastery Programme.

“The programme gave me the opportunity to rotate across different areas of the bank, which helped me build a strong understanding of how data science is applied in different contexts. I gained exposure to both retail and business banking, which was especially valuable in broadening my perspective beyond just one domain.”

As part of the programme, she also worked on a capstone project within the Business and Commercial Banking division where she redeveloped a credit scorecard model. 

“I presented this project at the programme showcase and graduation, which was a rewarding milestone and a great opportunity to apply my technical skills to a real business problem.”

After completing the graduate programme, Tiara transitioned to her current role as a data scientist in the bank’s Global Markets division. 

“I work on developing AI and data-driven solutions across different asset classes. A big part of my role involves building tools that help trading and sales teams process and interpret large volumes of information more efficiently.

“Markets change quickly, so the problems we solve are always evolving, which keeps the work interesting and challenging. I also really enjoy seeing how the models and tools we build are used by teams to support real trading decisions; it makes the impact of the work very tangible.”

She says one of the biggest lessons she has learnt so far is that you do not need to have everything figured out at the beginning of your journey.

“It is okay to explore different areas, gain experience and refine your direction over time. Some of the most valuable clarity comes from actually trying things out rather than trying to plan everything perfectly from the start.”

Her advice to students and graduates is not to underestimate the value of people and relationships.

“The connections you make whether with peers, mentors or colleagues often play a huge role in shaping your growth and opening doors you might not expect. Being proactive, asking questions and putting yourself out there really makes a difference.”

The Durban-born professional says she feels grateful for the journey she has had so far but believes there is still much more to learn and achieve.

“In five years, I see myself having developed a much deeper understanding of both the financial markets and the products within Global Markets. I want to build strong domain expertise alongside my technical skills, so that I can not only develop models and AI systems, but also truly understand the market context in which they are being used. My goal is to bridge the gap between technology and markets.

“I am looking forward to continuing taking on new challenges and contributing meaningfully in whatever I do.”
