What I'm looking for

I seek a role where I can build scalable ETL/ELT pipelines and data platforms, collaborate cross-functionally, use analytics to drive decisions, and grow into higher-impact technical or leadership responsibilities.

I am a Data Engineer and Analyst with practical experience designing and automating ETL/ELT pipelines using SQL, Python, Apache Airflow and PySpark, and implementing data lake and warehousing solutions on AWS and Snowflake to deliver analytics-ready systems.

I combine technical data engineering with business development experience, having grown partnership portfolios, led stakeholder engagements, and used analytics to improve reporting accuracy and operational efficiency across agricultural and retail contexts.
