Freelancer Overview

I am an experienced machine learning and AI engineer with a strong background in building and deploying data-driven solutions, including NLP and recommendation systems. My expertise spans the full data lifecycle—from data collection and preprocessing to model training, evaluation, and monitoring—using Python, SQL, and libraries such as scikit-learn, PyTorch, TensorFlow, and Pandas. I have led projects involving fraud detection, customer segmentation, and personalized recommendations in e-commerce and content streaming, where high-quality labeled data and robust annotation processes were critical for model accuracy. I am skilled at designing data pipelines, implementing reproducible experiments, and optimizing model performance with tools like MLflow, Docker, and FastAPI. My hands-on experience collaborating with cross-functional teams and translating business needs into actionable, data-centric solutions ensures that I deliver reliable AI models that depend on well-structured and accurately labeled datasets.

Labeling Experience

LLM Output Evaluation & Text Annotation Specialist

Internal Proprietary ToolingTextClassificationQuestion Answering
Worked on large-scale language model training and evaluation datasets focused on improving reasoning accuracy and instruction-following performance. Tasks included rating and annotating model-generated responses using structured evaluation rubrics. Evaluations covered correctness, logical consistency, hallucination detection, safety compliance, and relevance to prompts. I categorized outputs, identified systematic failure modes, and provided corrective feedback signals used for reinforcement learning fine-tuning (RLHF). Maintained high annotation consistency across large datasets and adhered to strict quality benchmarks. Participated in periodic quality audits and calibration tasks to ensure inter-annotator agreement and dataset reliability.
