What I'm looking for

I seek data roles where I can apply SQL and Power BI to improve AI model performance and drive actionable insights in collaborative, growth-focused teams.

I am a detail-oriented Junior Data Analyst with hands-on experience in data cleaning, validation, and AI model training, formally trained in the ALX Data Analytics program in 2025. I use SQL, Power BI, and Excel to extract, transform, visualize, and automate reporting, consistently improving workflow efficiency and reporting accuracy.

My background includes freelance data analysis for clients on Upwork and evaluation work with Appen, Lionbridge, OneForma and others, where I labeled datasets, conducted LLM evaluation, and ensured 95%+ data accuracy for AI/ML projects. I have built ETL pipelines, designed dashboards tracking multiple KPIs, and delivered actionable insights that improved client outcomes and reduced turnaround times.

I bring strong research and stakeholder communication skills from roles at the Kenya Revenue Authority and legal attaché work, and I am eager to apply my analytical and AI-data expertise in collaborative environments to enhance model performance and inform data-driven decisions.
