About me

An experienced data analyst with strong self-starter mindset adapted over 3 years working in scale ups, evolving brand-new roles at both Third Space and HelloFresh. Transformed large datasets from multiple complex systems into deliverable insights and predictive capability. With a strategic focus on end-user product experience I influenced SaaS feature adoption and workflow design during a multi-product implementation in a fast-growing business. I am committed to growing in data analytics, expanding my technical skills in Al, Python, SQL, and R, while consistently refining my technological knowledge inside and outside of work.
