What I'm looking for

I’m looking for remote AI roles where I can apply precise data cleaning, validation, and annotation QA. I want work focused on accuracy, systematic reviews, and dependable dataset delivery—fast turnaround with clear quality standards.

I’m an analytically driven BSc Public Health student with hands-on experience in data cleaning, structured analysis, and dashboard visualisation. I combine public health research context with certified data skills to support AI/ML training pipelines, data annotation projects, and AI-powered health analytics.

I’ve built production-ready, stakeholder-ready outputs from messy datasets—resolving duplicates, inconsistent formats, mixed-case text, and missing values—and translating results into KPI summaries and interactive dashboards. I’m eager to apply my pattern recognition, data validation, and critical evaluation skills to remote AI roles on platforms like Himalayas, where I can deliver accurate datasets with a fast, independent work ethic.
