What I'm looking for

I'm looking to build scalable cloud data pipelines, data migration solutions, and analytics platforms using AWS, PySpark, ETL/ELT, and event-driven architecture.

I've built AWS data migration and archival pipelines at Bizsaclabs Softtech, moving structured and unstructured data into Amazon S3 for analytics and search.

On a data migration archival pipeline, I designed RDS-to-S3 migration using AWS DMS and ingested unstructured Box data using EC2-based services. I built event-driven processing with S3 triggers, Lambda, and SQS, converting CSV files to Parquet and routing, validating, and processing files by data type.

I cataloged datasets with AWS Glue Crawlers, enabled Athena queries, and indexed unstructured content in Amazon OpenSearch. I also implemented retry logic, dead-letter queues, CloudWatch monitoring, and SNS alerting to improve pipeline reliability.

For an SAP-to-SAP migration, I developed AWS Glue Python and PySpark jobs to extract SAP Logistics data, apply incremental loads, cleanse and validate records, and manage raw and curated S3 layers. I optimized ETL performance through Parquet, partitioning, and Spark parallel processing.
