What I'm looking for

I'm looking for roles in AI training, data annotation, and model evaluation where I can apply my experience in data quality, machine learning, and cross-functional collaboration while continuing to learn.

At SIRCLO, I manage data across 350+ tables and build analytics-ready models with dbt Cloud, BigQuery, and PostgreSQL. I also support data governance through Unity Catalog documentation and infrastructure exploration in Databricks.

I developed a demand forecasting model across 200+ store-warehouse combinations, evaluating LSTM, XGBoost, CatBoost, and SARIMAX. The model achieved under 15% error for 11 high-volume locations during peak festive periods.

I've built AI products including a RAG-based bug triage chatbot, a CV scoring and feedback model, and computer vision labeling workflows across 200+ datasets. As a freelance AI Data Annotator at RWS, I evaluate and tag audio, video, and image data for AI training.

My projects include Emoby, a CNN-based child maltreatment emotion-recognition system that reached 80% accuracy, and PatientRePro, a hospital readmission prediction project that achieved an 81% F1-score. I enjoy improving data quality, model performance, and decision-making through practical analytics and AI work.
