Freelancer Overview

I am a detail-oriented data entry analyst and software tester with hands-on experience managing, organizing, and ensuring the quality of large datasets. My background includes overseeing data input operations, conducting rigorous quality checks, and maintaining data integrity in fast-paced environments. As a freelance software tester at Test IO, I have honed my analytical and communication skills through structured and exploratory testing, providing precise feedback and documentation to improve digital products. My ability to identify inconsistencies, follow detailed guidelines, and collaborate with teams makes me well-suited for data labeling and AI training data roles. I am committed to accuracy, confidentiality, and continuous learning, and I thrive in roles that require both precision and adaptability.

Labeling Experience

I worked as an AI Trainer on a transcription project focused on training and improving large language models (LLMs) and speech-to-text systems. The project involved accurately transcribing audio data into text to support model training, evaluation, and fine-tuning for natural language understanding tasks. My responsibilities included producing high-quality transcriptions following strict guidelines, including verbatim accuracy, speaker labeling, punctuation, and formatting. I handled challenging audio scenarios such as different accents, overlapping speech, background noise, and varying audio quality. The work required careful attention to linguistic detail to ensure the transcribed data aligned with LLM training requirements.

Image Annotation

AppenImageBounding BoxPrompt Response Writing SFT

I worked as an AI Trainer and Data Scientist on an image annotation project supporting the development of computer vision and machine learning models. The project which am unable to mention as part of NDA protocols involved annotating large-scale image datasets using bounding boxes to identify and localize objects of interest for tasks such as object detection and image classification. My responsibilities included drawing precise bounding boxes around target objects according to strict annotation guidelines, reviewing labeled data for accuracy and consistency, and handling edge cases to ensure high-quality training data. I also participated in quality assurance processes, validating annotations and correcting errors to maintain dataset integrity.
