Problem Statement

Manual extraction and transformation of unstructured files was throttling the business — long data-preparation cycles, delayed availability for analysis, and a hard ceiling on how quickly the organisation could turn raw data into decisions.

Manual processing of unstructured files caused prolonged data-preparation times.
Delayed data availability slowed analysis and time-sensitive decisions.
Heavy manual intervention made the pipeline brittle and hard to scale.

The Solution

An automated, dynamic ETL pipeline on AWS — extracting and transforming unstructured files at scale, orchestrating millions of records per day through 100% API automation, and landing analytics-ready data in Redshift with Apache Hudi for upsert-friendly, incremental processing.

Automated extraction and transformation of unstructured files end-to-end on AWS.

100% API automation orchestrates the daily extraction of millions of records.

Apache Hudi enables efficient incremental upserts into Amazon Redshift.

Athena and S3 provide cheap, serverless query and storage across the data lake.
