What I'm looking for

I’m looking for a role where I can build Power BI dashboards and end-to-end analytics, partner with stakeholders, and also apply data engineering and AI model evaluation to improve data quality and decision-making.

I deliver measurable business outcomes through the full analytics lifecycle, from data collection and cleaning to EDA, KPI tracking, predictive analytics, and visualization. With 3+ years of hands-on experience, I’ve reduced manual data processing by 40% and cut reporting turnaround from 2 days to same-day.

I’m proficient in Power BI (DAX, slicers, reports), Tableau, and Streamlit—building interactive, self-serve dashboards that help non-technical stakeholders explore trends and make decisions. On the engineering side, I use Python (Pandas, NumPy, Scikit-learn, Matplotlib) and SQL (joins, CTEs, window functions) to perform statistical analysis, identify key drivers, and support repeatable reporting and ML pipelines.

Right now, I’m contributing as a Data Trainer focused on AI model training and data quality evaluation—validating outputs for accuracy, relevance, and alignment with best practices. I value clear documentation, governance, and cross-functional collaboration, and I’m motivated by work that turns analytics into real-world impact.
