Freelancer Overview

I am a detail-oriented Data Labeling Specialist with hands-on experience delivering high-quality training data for machine learning models across image, text, video, and audio domains. My work includes precise bounding box and polygon annotation for computer vision projects, text categorization for NLP applications like chatbots, and audio transcription and labeling for speech recognition systems in both English and Bangla. I am skilled in using industry-standard tools such as Labelbox, CVAT, LabelImg, and Prodigy, and have a strong commitment to accuracy, often achieving 99%+ precision in my annotations. I thrive in fast-paced freelance environments, excel at quality assurance and peer review, and understand the importance of data privacy and consistency to support the development of robust, unbiased AI solutions.

Labeling Experience

Freelance Data Annotator – Audio Processing

LabelboxAudioTranscription

I transcribed audio files in both English and Bangla to support training for speech recognition models. The transcription process required careful attention to detail and linguistic accuracy. I worked on diverse audio sources, delivering labeled outputs within set timelines. • Tagged and segmented speaker turns and timestamps • Maintained high transcription accuracy standards • Addressed linguistic challenges in multilingual datasets • Improved overall dataset quality for model training
