I’m a detail-oriented data annotation specialist and video reviewer based in Lagos, Nigeria, with hands-on experience labeling video footage for AI training. I break down episodes into atomic, event-based human actions and apply precise bounding box and polygon annotations while working inside audited QA pipelines that use IoU-based accuracy scoring and guideline consistency checks. I’m also comfortable with de-identification work (blurring/redacting faces and sensitive identifiers) and with dispute/sampling review workflows to ensure labels meet strict thresholds. Alongside my annotation work, I have strong written English, high typing accuracy, and experience as a transcriptionist, content writer/translator, and freelance contributor—so I can communicate clearly in remote, deadline-driven environments.…

    Health Care Dashboard Sample
    The goal of this project was to design a comprehensive, intuitive, and data-driven dashboard that centralizes key hospital outpatient metrics. The objective was to transform raw, complex healthcare data into clear, actionable insights to help medical administrators and department heads monitor performance, track patient visits, and improve operational efficiency. What I Made Outpatient Metrics Tracker: Built a centralized view tracking core Key Performance Indicators (KPIs) such as total patient volume, wait times, satisfaction scores, and department-specific performance percentages. Departmental Analysis: Developed clear visual breakdowns comparing patient volume and efficiency across various hospital departments (e.g., General Practice, Orthopedics, Pediatrics, Cardiology). Trend Visualizations: Integrated clean charts and graphs—including monthly visit trends and department distribution metrics—to provide a quick snapshot of patient flow over time. Data Formatting & Organization: Structured the layout with clean conditional formatting (highlights for key targets) to ensure high-priority data points stand out instantly. The Result The resulting dashboard provides healthcare managers with a powerful decision-making tool, reducing the time spent analyzing monthly reports by streamlining patient data into a single, easy-to-read interface.…
