About

I am a dynamic professional with a diverse background spanning business management, technical support, B2B sales, and creative production. I have led teams, optimised operations, and communicated effectively across roles in retail, hospitality, technology, and digital media.

I am a continuous learner with a robust track record of building real-world analytics and deep learning solutions — including image recognition, text classification, and unsupervised clustering. I work end-to-end on ML workflows, from data cleaning and feature engineering to model selection and visualization, and I enjoy translating complex data challenges into actionable business insights.
