What I'm looking for

I’m looking for a data analyst role where I can use SQL, Power BI, and Python to improve data quality, build dashboards, and deliver accurate, business-focused insights that support data-driven decisions.

I’m a Computer Engineering graduate and data analyst focused on improving data quality, optimizing queries, and delivering accurate, business-focused analytical solutions. I write complex SQL queries, perform data cleaning and validation, and build structured datasets for reporting and dashboarding.

In my internships, I used machine learning and statistical methods to extract actionable insight—like customer segmentation with K-Means/DBSCAN/HDBSCAN/GMM and time-series forecasting. I also built an LLM RAG chatbot using FLAN-T5 with vector database retrieval, and applied causal impact analysis using Propensity Score Matching and Mann–Whitney U testing.
