Scope: Contributed to an AI training project focused on improving speech recognition and audio quality models. The task involved listening to voice recordings and evaluating them against a defined rubric. Specific Task: Classified audio samples by quality, clarity, and accuracy of speech based on detailed annotation guidelines. Applied labels to indicate issues such as background noise, mispronunciation, or unclear articulation. Quality Measures: Maintained strict adherence to labeling rules, cross-checked ambiguous cases, and consistently met accuracy and throughput benchmarks set by the project. Ensured high-quality annotations to support model training and validation.

Scope: Supported a computer vision project aimed at distinguishing coffee bean varieties (Arabica, Robusta, Liberica) for model training. Used Roboflow as the primary platform for dataset preparation. Specific Task: Annotated images by drawing bounding boxes around individual coffee beans and labeling them by type. Ensured consistency in annotation across large datasets to enable accurate classification and detection. Quality Measures: Followed dataset annotation standards, reviewed annotations for precision, and validated bounding box placement to minimize labeling errors. Maintained consistency and accuracy to ensure high-quality training data for robust computer vision models.
