What I'm looking for

I am seeking a junior/mid-level analytics role where I can apply automation and EDA skills, work cross-functionally, and contribute to process efficiency and actionable insights.

I am a detail-oriented junior data analyst with hands-on experience in data cleaning, exploratory analysis, and automation. I have applied Python and Excel to uncover trends and deliver actionable insights that support business decisions.

During my internship at Deviare I partnered with senior analysts to build Tableau visualizations and instituted an automated reporting system that saved 15 hours of manual work each week. I also contributed to predictive-modeling efforts in a virtual traineeship with Numadic that helped reduce delivery times by 10%.

My training includes an NQF Level 5 Diploma in Data Science and an NQF Level 4 certification in Mechatronics, which underpin my technical and analytical foundation. I am comfortable working in cross-functional teams and translating data findings into clear stakeholder-facing reports.

I am motivated to leverage strong organizational skills, attention to detail, and a practical understanding of analytics and automation to support underwriting and operational efficiency in insurance or logistics-focused teams.
