LEBOHANG RAMATLAPENG
@lebohangramatlapeng
Data annotator and software developer focused on accurate, efficient ML-ready datasets.
What I'm looking for
I’m a detail-oriented Data Annotator and Software Developer with hands-on experience preparing and labeling datasets for machine learning applications. I focus on accuracy, consistency, and efficiency, so training data stays reliable across projects.
In my current role, I annotate and label datasets for multiple machine learning model training efforts, maintaining high accuracy in tagging and performing quality checks and validation against project standards. I collaborate with developers and researchers to improve dataset structure and usability.
Alongside data work, I build software projects that strengthen my ability to deliver usable, user-friendly experiences. I’ve developed interactive applications, including a secure multi-page desktop GUI with authentication, a 3D futuristic city simulation using OpenGL, and a responsive frontend web application with form validation.
