Industry Experience

Manufacturing, Real Estate & Construction, Professional Services, Transportation & Logistics
    Executive Report and Presentation Formatting

    Self-directed portfolio sample demonstrating how raw business information can be converted into a clear executive report and presentation. I organized the content into a logical narrative, simplified dense text, standardized headings and tables, corrected formatting inconsistencies, and highlighted decisions, risks, and next actions.

    The deliverables were designed for quick management review, with concise summaries, consistent visual hierarchy, readable charts and tables, and professional handover formatting.

    Tools and skills: Microsoft PowerPoint, Microsoft Word, presentation design, report formatting, information hierarchy, proofreading, and executive summaries.

    Business Lead Research and Verification

    Self-directed portfolio sample showing a practical lead-research and verification workflow for small-business outreach. I defined the target criteria, collected relevant company information, checked official websites and public contact sources, removed duplicates, and organized the results into a clean action-ready spreadsheet.

    The final structure included company name, website, location, business category, contact channel, source link, verification status, notes, and priority. Quality checks were used to reduce outdated or incomplete records.

    Tools and skills: web research, data collection, source verification, spreadsheet organization, duplicate removal, and concise business summaries.

    Excel Data Cleanup and Quality-Control Workflow

    Self-directed portfolio sample demonstrating a structured Excel cleanup workflow for business records. I normalized dates and names, removed duplicates, corrected inconsistent formats, flagged missing values, and added validation and quality-control checks.

    Deliverables included a clean master sheet, an issue log, a concise summary dashboard, and clear handover notes. The workflow is suitable for CRM exports, sales lists, invoices, inventory records, and operational reports.

    Tools and skills: Microsoft Excel, formulas, filters, conditional formatting, pivot tables, data validation, and accuracy checks.
