Data Analyst • Data Scientist • Python Developer

Building data-driven products that transform complex datasets into actionable business insights.

I specialise in Python, SQL, statistical analysis and machine learning to solve business problems through analytics, predictive modelling and intelligent data applications.

About Me

I'm a Computer Science undergraduate with a strong interest in applying data to solve practical business problems.

My work spans data analytics, machine learning and Python development, with growing domain expertise in product analytics and financial risk analysis. I enjoy turning messy datasets into meaningful insights, building predictive models and developing tools that help organisations make better decisions.

Outside academics, I spend most of my time building projects, studying modern analytics practices and continuously improving my technical skills through hands-on development.
