What I'm looking for

I seek a technical role leveraging annotation and transcription expertise on AI or data teams, with confidentiality, growth, and measurable impact.

I am a detail-oriented data annotation and transcription specialist with formal training in Business Information Technology (DBIT) and data analytics tools including Excel and Power BI. I have delivered high-accuracy financial transcripts and worked closely with AI teams to refine transcription models.

At SamaSource I performed 3D LiDAR point cloud annotation, created precise 3D bounding boxes, and used tools such as SuperAnnotate and CVAT to maintain annotation quality; my work contributed to 98% dataset accuracy and a 15% productivity improvement in annotation workflows.

As a freelance financial transcription editor and customer service professional, I upheld strict confidentiality and regulatory compliance, achieved transcript accuracy up to 99.9%, and reduced call resolution times while maintaining strong client satisfaction. I seek roles where I can apply analytical rigor, technical annotation skills, and customer-focused problem solving.
