What I'm looking for

I seek a cloud-focused data engineering role where I can build scalable data platforms (AWS/Azure), improve ETL/Delta Lake pipelines, work in collaborative teams, and grow into platform or architecture responsibilities.

I am an accomplished data engineer with over 4 years of experience designing, developing, and optimizing large-scale data engineering pipelines across AWS and Azure. I build end-to-end data lake architectures and reliable ETL/ELT workflows using tools like AWS Glue, EMR, Redshift, Azure Data Factory, Databricks, Synapse, and ADLS.

My projects include modernizing on-premise Hadoop platforms to cloud-native Azure architectures for a US healthcare provider and implementing an AWS-based data platform for Woolworths, where I developed PySpark ETL, orchestrated workflows with Step Functions, and enabled analytics with Athena and Redshift. I emphasize data quality, incremental processing, performance tuning, and cost optimization.

I collaborate with stakeholders for continuous delivery, monitoring, and secure operations using GitLab, CloudWatch, Azure Monitor, and Key Vault, and I adapt quickly to new technologies while maintaining strong communication and team skills.
