What I'm looking for

I seek a collaborative role where I can build ETL pipelines, automate reporting, and apply analytics to drive operational improvements and measurable business impact.

I am a Data Analytics Engineer with 4+ years of experience in telecom and logistics, focused on data mining, pipeline analysis, and data management. I design automated reporting tools, build ETL pipelines, and create visualizations that improved network efficiency by 20% and reduced manual reporting effort by 25%.

I have built internal data collection tools, ingested and modeled data using Python, SQL and Airflow, and presented analyses to senior leadership to influence product and pricing decisions. I thrive on cross-functional collaboration, solving operational problems, and expanding my technical skill set.
