What I'm looking for

I’m looking for a remote, part-time role where I can apply my skills in data entry, data analytics, and reporting to support organizational goals. I’d love to join a team that offers opportunities to learn, grow, and contribute, especially in areas involving spreadsheets, Power BI, and emerging technologies.

I’m a detail-oriented Data Analyst and Data Entry Specialist with experience managing, cleaning, and visualizing data to support smarter decision-making. Skilled in Excel, Power BI, and Google Workspace, I enjoy creating dashboards, ensuring accuracy in large datasets, and turning complex information into clear insights. I hold both the Google Data Analytics Professional Certificate and a HIPAA certification, underscoring my commitment to confidentiality and data privacy. My background spans real estate operations, administrative support, nonprofit volunteering, and multilingual communication—I’m fluent in Spanish, English, and Haitian Creole.

Beyond technical expertise, I bring reliability, accuracy, and strong communication skills. I thrive in collaborative environments and enjoy contributing to teams that value curiosity, critical thinking, and innovation. I’m also passionate about emerging technologies, especially AI, and regularly use tools like ChatGPT, Gemini, and Claude AI to boost productivity and problem-solving.

My goal is to keep growing in data analytics while helping organizations improve processes, strengthen reporting, and make decisions driven by trustworthy data.
