Message

At Oasis Infobyte, I’m currently working as a Data Scientist intern. My background includes IBM certifications in data science and data engineering.

As an Intelligence Specialist at the South African Department of Defence, I’ve worked in high-stakes intelligence environments. I bring that experience to structuring complex problems and building robust data workflows.

I’m completing a BCom in Quantitative Management Science at University of South Africa/Universiteit van Suid-Afrika. My studies cover optimisation, simulation, stochastic modelling, forecasting, and risk modelling, alongside technical training in Python, SQL, ETL, and machine learning.
