Freelancer Overview
Programme Officer – Data Labeling and Validation. Brings 5+ years of professional experience across complex professional workflows, research, and quality-focused execution. Core strengths include Microsoft Excel.
Education includes a Bachelor of Science in Economics Education, Usmanu Danfodiyo University, Sokoto. AI-training focus includes data types such as Document and labeling workflows, including Classification.
I have hands-on experience working with both structured and unstructured data through my background in monitoring & evaluation, research, and program implementation. While my roles were not titled “data annotator,” they involved core data labeling tasks such as data categorization, validation, and quality control.
One key area of experience is survey and field data processing. I worked on projects where I collected and handled over 500+ survey responses, organizing and categorizing qualitative and quantitative data into structured formats for analysis. This involved tagging responses, cleaning datasets, and ensuring consistency and accuracy before reporting.
I have also worked extensively with structured datasets using Excel and Google Sheets, where I performed data cleaning, validation, and classification. I regularly identified inconsistencies, corrected errors, and maintained high data accuracy (typically 98%+), which aligns closely with data annotation quality standards.
In addition, I supported research and reporting activities by labeling qualitative data from interviews and focus group discussions. This included grouping responses into themes, tagging key insights, and preparing structured outputs for decision-making.
I am currently expanding my expertise into AI-specific annotation tools and workflows, including image and text annotation, and I am familiar with annotation guidelines, quality assurance processes, and task-based labeling environments.
Overall, my experience has equipped me with strong attention to detail, consistency in applying guidelines, and the ability to work efficiently with large datasets, skills that directly translate into high-quality data labeling and annotation work.
