AudioI’ve worked on project-based data and AI-related tasks through freelance and contract platforms commonly used in the U.S., including Upwork, Indeed contract listings, andLinkedIn roles. I have two years of experience in Python as well. Alongside my background as a data analyst, this work involved labeling and validating datasets, reviewing AI-generated text for accuracy and relevance, categorizing content according to detailed guidelines, and performing quality checks to ensure consistency across training data. I also completed tasks such as sentiment labeling, relevance scoring, and reviewing mobile-based data submissions. I have been learning how AI systems work mostly through YouTube videos, podcasts, and through friends. In 2022, I moved from California to Berlin to pursue a degree in Engineering. I still have much to learn about being a professional Data Analyst but I can promise you great results and I will meet deadlines.
I evaluated user submitted audio clips for content relevance and adherence to project guidelines. These are the kind of projects I enjoy the most.
I reviewed audio recordings to evaluate clarity, accuracy, and transcription quality for speech recognition AI models. I rated each clip based on audio quality, speaker intelligibility, and background noise, and flagged segments that were unclear or unusable.
I flagged errors or inconsistencies and documented edge cases to improve labeling instructions. This work ensured that the AI models powering the mobile app received reliable training data.
I evaluated AI chatbot responses for relevance, clarity, and accuracy. I rated each response according to detailed guidelines and provided feedback on improvements. This work helped refine natural language generation models and improve user interactions with the chatbot.
I reviewed product and user-submitted images and their metadata.
