About

Professional summary

I am an insurance data and operations professional with 15 years of experience spanning underwriting, claims, risk analysis, compliance, and operations management. I hold a Bachelor of Science in Actuarial Science and use analytical methods to improve decision-making, service delivery, and risk controls.

I work with SQL, Python, R, Tableau, and advanced Excel to clean, validate, analyze, and visualize data. My work includes claims trend analysis, frequency and severity modelling, loss reserving, KPI reporting, predictive analysis, financial modelling, and dashboard development.

In my operations leadership role, I oversee medical insurance schemes serving more than 4,500 principals and 20,500 beneficiaries while leading an 11-person team. I have streamlined workflows to achieve 95% SLA compliance, reduce processing time by 30%, and improve productivity by 20%.

I have strong experience in claims analytics, underwriting support, public liability claims, fraud and validity investigations, pricing support, and risk exposure monitoring. I have also reduced claim disputes by 25% through stronger verification controls, issue resolution, and process improvements.

I am experienced in insurance compliance, including IRA and AML-CFT requirements, SOP development, management reporting, root-cause analysis, vendor negotiation, and CRM and claims automation initiatives. My work has contributed to zero IRA non-compliance and approximately KES 2.5 million in annual vendor savings.

Since January 2026, I have also worked as a freelance AI trainer and evaluator for US-based AI companies. I evaluate and rank LLM outputs, write and review prompts, assess training data quality, and test models for factual accuracy, domain validity, and bias.
