What I'm looking for

I’m looking for a role where I can build reliable SQL/ETL pipelines, deliver clear Power BI/Tableau dashboards, and support predictive modeling. I want a fast-paced team that values data accuracy, documentation, and problem-solving on large datasets.

I’m a Data Analyst with 3.5+ years of experience across SQL development, ETL, dashboarding, and exploratory analysis. I focus on turning raw data into accurate, business-ready reporting and insights that teams can act on confidently.

In my recent role at Clearline Group, I automated data integration workflows using Groovy, CalcScripts, REST APIs, and SQL. I also improved the accuracy of financial reporting through optimized metadata and reconciliation logic, and built SQL logic for planning, budgeting, and variance analysis.

Previously, at Censanext, I optimized SQL and NoSQL queries to improve database performance and reduce latency, and I designed PostgreSQL and MySQL schemas for new application modules. I’ve also built end-to-end analytics pipelines—like forecasting product sales from 8+ relational tables using Python and ML models (Linear Regression, Random Forest, XGBoost)—and I create dashboards in Power BI, Tableau, and Excel to communicate trends and KPIs clearly.
