What I'm looking for

I'm seeking a junior Analytics Engineering, Data Engineering, or Data Analytics role where I can build data pipelines, analytics-ready datasets, data models, and reporting solutions.

I've built analytics engineering projects focused on transforming raw data into clean, reliable, and well-structured datasets using SQL, dbt, Databricks, and Python. My work includes data modeling, validation, automated quality checks, incremental transformations, and preparing data for analysis and reporting.

I've also created Power BI projects covering Austin Airbnb market dynamics, Olist e-commerce sales and logistics, and telecom customer churn. These projects involved data cleaning, KPI definition, trend analysis, and interactive dashboards focused on pricing, customer retention, delivery performance, revenue, and regional insights.

I enjoy working with data quality, analytical problem-solving, and improving the way data is prepared and used for decision-making.
