What I'm looking for
I am a Senior Data Engineer with over 6 years of experience designing, developing, and maintaining scalable ETL/ELT pipelines and enterprise data warehouse solutions.

I build and deploy AWS data solutions using Amazon S3, AWS Lambda, AWS Glue, Amazon RDS, and Amazon ECS, and I apply Python-based data processing alongside DevOps CI/CD practices. My work includes dimensional modeling, ELT workflows, and tuning large-scale data pipelines to reduce runtimes and improve query performance.
Across roles I have optimized SQL queries and indexing strategies, reduced ETL batch runtimes, automated data validation with Python, and supported containerized and orchestration solutions. I focus on reliable, maintainable data platforms that enable faster insights and scalable analytics.
