At Sigmoid Analytics, I designed relational data models that improved reporting efficiency by about 25%, and built and maintained 50+ Power BI dashboards for business KPIs. I also analyzed paid social campaign performance for enterprise brands and automated media-planning roadmaps with Python.
I automated recurring reporting with Python and Openpyxl, and built AI-assisted chatbot tools for natural-language data queries. In a personal project, I built a logistic regression fraud detection model that achieved 92.8% accuracy.
