Building serious systemsand curious experiments
This is a living portfolio of what I build outside day-to-day roles. The fastest way to grow is to design, run, and debug real systems end to end. Open to new roles and available for IT consulting.
Main Focus Right Now: Enterprise Homelab
I am building an enterprise-style environment at home to gain practical experience that many job descriptions ask for but most roles do not provide enough room to practice deeply.
A big part of that work is identity architecture, including FreeIPA and Samba AD trust design, but the full project spans segmentation, Zero Trust access, observability, and automation. For the complete picture, read the Enterprise Homelab write-up.
Segmentation, policy enforcement, remote access boundaries, and service design in a full-stack home lab environment.
FreeIPA, Samba AD trust relationships, and group-driven policy models across mixed environments.
A collaborative drone detection project using SDR to decode Remote ID signals and turn telemetry into usable visibility.
Experimental build exploring window-mounted exciters to reduce side-to-side voice leakage in apartment spaces.
LED installations were my technical starting point and pushed me toward richer embedded controls, interaction design, and systems thinking.
Ansible workflows, service checks, and policy validation that keep projects repeatable, stable, and easier to operate long term.
