Freelancer Overview

I am a Computer Science Engineering graduate with hands-on experience in AI model evaluation, data annotation, and human-in-the-loop training workflows. My work spans coding, reasoning, text, image, and voice tasks, where I assess model-generated solutions for correctness, contextual accuracy, and prompt compliance. I have a strong foundation in Java and Python, enabling me to review and debug code for logical consistency and edge-case handling in large-scale AI training environments. My experience includes providing structured feedback within RLHF pipelines, multilingual annotation (Kannada–English), and voice transcription validation. I am skilled in tools like Git, VS Code, and Jupyter Notebook, and have contributed to machine learning projects in the medical domain, such as building a thyroid disease prediction system using Scikit-learn and Pandas. I am committed to maintaining high quality and efficiency across AI data labeling and evaluation tasks.
