Employment
Experience
- Data Migration from Azure SQL to Snowflakehttps://github.com/innowarue/ADF
This project involved migrating data from an Azure SQL database to a Snowflake data warehouse using an Azure Data Factory data pipeline. It took me minutes to create it based on my skill set and proficiency in Data Factory.
I replaced the authentic data sources with my Azure and Snowflake accounts to make the project publicly available without compromising confidentiality. - Data Integration from OAuth2 API
I created an automated data pipeline to integrate data accessible via an OAuth2-based API in JSON format into a cloud-based data warehouse solution. The solution used Python and Spark on Databricks integrated into an Azure Data Factory pipeline.
- SQL Server Replication to Mobile Devices
I created a replication system that synced data between mobile devices and Microsoft SQL Server. Field sales representatives would collect information from the field, upload it to SQL Server using SQL CE and download any updates from SQL Server via the mobile replication I set up.
- In-place Data Integration for an Acquisition
I created an in-place ETL integration for a company acquisition and merger, bringing the two companies' data into a single warehouse while continuously delivering weekly reports to the client services and retail service teams.
- Kafka Streaming and Data Integration
I created an automated data pipeline to integrate data accessible via a Kafka stream, ingesting it into Spark Streaming using Spark and Python and loading it into a Cloudera Hadoop file system accessible using a Hive data warehouse solution.
