This positively impacted the company by introducing new input data for Data Scientists in the GCP environment with Big Query.- Simple data pipeline for Google Analytics and Zendesk data using AWS AppFlow that feeds an AWS S3 bucket directly to substitute a legacy data pipeline written in Python and Luigi, which reduced technical debt a lot since similar data pipelines wouldn’t need to be created with programming languages directly, so anyone can maintain it.- Data pipelines for third-party services that fetch Venmo App usage metrics, using AWS Lambda functions to fetch, transform, and send data to Snowflake.- Data pipelines for the entire organization’s data, using AWS solutions to get data from multiple sources such as SQL and NoSQL data. Python and Luigi were used for fetching, transforming, and committing data to a Snowflake instance.Technologies and concepts used:Programming languages: Python.Data Engineeering: Luigi, Apache Spark, AWS EMR, AWS Lambda, AWS CloudWatch and AWS EventBridge.Databases and storage: MySQL, MongoDB, Snowflake and S3.Infrastructure: AWS CDK and GHA.
