Summary
I’m a hands-on Senior Lead Software Engineer who is interested in new technologies and innovative ideas. Here are some things I bring to the table:
- passion
- quality
- accuracy
- code
- humor
- …food
I believe that the best code is a product of a fun environment and an amazing team.
My colleagues and mentees alike always say they have learned a lot from me, especially as a result of my passion and patience.
Education
Experience
- Contributed to event-driven login/authentication messaging (decommissioned)
- Contributed to enterprise-wide enrollments, offering technical expertise in microservices design and implementation.
- Influenced my organization regarding “shift-left” best practices.
- Resolved multiple performance and vulnerability issues through cross-team collaboration.
- Fixed an internal enterprise Spring library’s performance degradation related to error caching (again, Caffeine cache) that impacted every application using the library.

This tool reads AWS configurations regardless of the application’s original CI tool and outputs the configurations necessary for the enterprise’s standard CI/CD pipeline (internal).

Projects
I have been active in Open Source officially since 2008, although I dabbled in coding for 20 years before that. College awoke an interest in me to share my code and creations with others.
The following is only a subset of the 150+ open source projects I have created.
New Tab Redirect!
A Google Chrome extension which allows the user to override the browser’s new tab page.
jimschubert/changelog
A CLI written in Go which allows for customizable changelog generation from local or remote (GitHub) repositories.
I also distribute this tool as a GitHub Action called beast-changelog.
jimschubert/answer
A Go module providing “bubbles” (bubbletea models) which provide terminal interface functionality to replace the deprecated github.com/AlecAivazis/survey.
jimschubert/venom
A documentation command for your CLIs built on top of cobra. I wrote this to output proper documentation for
commands with
/ in their names. I had contributed a fix to cobra
and waited a year without merge before implementing my own library to solve the problem.OpenAPI Generator Plugin
An extension for Jetbrains based IDEs which provides a GUI wrapper around OpenAPI Generator.
Publications
I extend my dedication to developer productivity into writing and performing technical reviews of written works.
Your First App: Node.js by Jim Schubert
I self published this book about the development life cycle of a full-stack node.js application, using Express/Angular/MongoDB.
Deploying Node.js by Sandro Pasquali
I was a technical reviewer for this book, which focused on the building, testing, deploying, monitoring, and maintenance of node.js applications.
