Background

About Joshua Shaffer

I’m a Data Engineer focused on building automation, ETL pipelines, and internal tools that replace manual, time-consuming processes with scalable software solutions.Across multiple roles, I’ve worked on systems involving Java, C#, SQL (SQL Server, MySQL, PostgreSQL), Snowflake, and APIs like Salesforce, NetSuite, and TalkDesk. A big part of my work has been connecting disconnected systems and turning manual workflows into automated, reliable processes.Most of my projects center around one goal: eliminate repetitive work and improve data accuracy. That’s included everything from modernizing 20+ year-old legacy systems, to building reporting automation pipelines, to designing ETL processes that handle large-scale user and data migrations.Through this work, I’ve helped remove 200+ hours of manual effort across reporting, data migration, and operational workflows by building tools that teams can actually rely on and extend.I enjoy stepping into messy or outdated systems, figuring out how they work, and rebuilding them into something cleaner, faster, and maintainable. I also focus heavily on making tools usable—building UI-driven applications so non-technical users can easily interact with automation instead of manual processes.Technologies I work with regularly include Java, C#, SQL, ETL pipelines, Snowflake, APIs, Selenium, AutoIt, and enterprise data systems.
