What I'm looking for

I am seeking entry-level data entry or freelance roles where I can apply spreadsheet skills, accuracy, and strong customer-service experience while growing professionally.

I am a third-year Electronics Engineering student with practical experience in data entry, customer service, and basic data analysis using spreadsheets. I have managed daily cash transactions, processed payments, maintained accurate records for academic experiments, and stepped into managerial duties when needed.

I bring strong organization, attention to detail, and clear communication to data-focused roles such as Data Encoder, Data Entry Specialist, or freelance projects. I leverage Excel, Google Sheets, and basic Canva design skills to deliver accurate, well-documented work under time constraints.
