What I'm looking for

I'm seeking a Clinical Analyst, Claims Analyst, or Health Data Analyst role where I can apply healthcare data management, clinical coding, claims analytics, and reporting to improve operational performance and decision-making.

I've improved health insurance operations through clinical coding, claims analytics, and reporting systems that turn complex data into action. My work spans 16 years of clinical and health insurance operations experience, supported by an MBBS and postgraduate degrees in Health Informatics and Public Health.

At Avon HMO, I built Excel provider-tariff comparison tools and a Power BI claims-submission dashboard, while supporting ICD-10 coding and quarterly clinical reporting. I also led an online claims submission system upgrade that improved submission-to-payment turnaround time by 40%.

Across Health Partners HMO and Hygeia HMO, I developed utilisation, claims, and provider-contract tracking systems that reduced hospital wait times by 35%, increased provider contract renewals by 60%, and cut tariff-update turnaround by 30%. I led claims teams, software migration, coding training, data-protection processes, provider negotiations, and operational reporting across large provider networks.

I'm building further hands-on analytics capability through SQL, Power BI, Excel, and Microsoft Fabric projects using healthcare and public-health datasets. I'm seeking a Clinical Analyst, Claims Analyst, or Health Data Analyst role where I can improve data quality, reporting, claims processes, and operational decisions.
