I’ve built data products and models across Diaspora Kapita, Kendago, and DataAnalyst roles on platforms like LinkedIn’s data workflows. At Diaspora Kapita, I designed dimensional data models and developed Power BI dashboards that improved executive reporting decision-making efficiency by 30%.

I’ve also developed end-to-end data pipelines and real-time KPI reporting with Power BI Apps, backed by automated data integration using SharePoint lists. I used SQL Server Management Studio for reliable storage management and automated daily database backups to protect data integrity.

On the modeling side, I’ve done feature engineering, preprocessing, training, and evaluation with scikit-learn—supporting forecasting and business decisions through clustering, regression, and classification. I’ve also supported A/B testing, hyperparameter tuning, and model evaluation for better experiment and model outcomes.

More recently, I’ve worked on conversational RAG research and scoping at LinkedIn, including defining problem statements, exploring EDA on sample datasets, and building proof-of-concept chatbot flow mock-ups. I enjoy bridging data preparation, model work, and practical product requirements.
