About Me

Jeremiah Kroesche | Halfservers LLC

I'm a systems-oriented developer and infrastructure engineer passionate about building clean, performant solutions. Currently completing a Diploma in Network Management & Cybersecurity at Southeast Community College while running Halfservers LLC.

From hardware assembly through cloud architecture, from penetration testing to CI/CD automation — I bring a detail-oriented approach to every layer of the stack. Whether it's a custom web application, server infrastructure, or technical consulting, I focus on solving problems that matter.
