What I'm looking for

I’m seeking a paid internship or junior data role where I can apply SQL, Excel and Power BI, learn on the job, and contribute to accurate, actionable data products.

I am a detail-driven junior data analyst with hands-on experience applying data every day across field operations, AI annotation and trading. I have completed formal training in Excel, SQL and Power BI and bring practical skills in KPI monitoring, dashboard design and structured data validation.

At Outlier.ai / Multimango I reviewed and quality-checked large batches of AI-generated data, assessed model outputs, and provided feedback that improved training-data quality. In field telecom roles I monitored live site KPIs, analysed equipment logs to find root causes, and produced clear maintenance reports for technical and non-technical stakeholders.

I pick up tools quickly, prioritise accuracy and documentation, and I’m committed to building a data-analysis career where I can turn reliable, validated datasets into actionable insights and measurable improvements.
