## About

```text
At OlaClick, I turn questions from Finance, Customer Success, Product, and leadership into SQL analysis, Python findings, and dashboards for churn, retention cohorts, MRR, and weekly activation. I automated recurring reporting in Amazon Quick Suite, reducing generation time by 50% and improving accuracy by about 10% through data-quality checks.

I built a payment-fraud risk model and Amazon QuickSight dashboard on Aurora PostgreSQL, and an XGBoost churn model with SHAP explanations that scores about 9,300 accounts weekly. Finding and fixing a feature that was constant at zero raised the churn model’s ROC-AUC from 0.7191 to 0.7319. I’m looking for a well-scoped role on a team with senior review.
