TJ Estrella
Network Engineer
I build and support practical network environments with a focus on switch installation, configuration, troubleshooting, and infrastructure readiness.
My work includes physically stacking and deploying Layer 2 and Layer 3 switching environments, supporting Cisco and Juniper-based projects, troubleshooting equipment in the field and in the lab, and helping guide network migration planning.
I also contribute to technical documentation and project execution workflows, with a long-term focus on expanding deeper into infrastructure engineering, self-hosting, and systems-driven work.

Projects
A self-hosted Matrix chat environment built as part of my long-term infrastructure and platform ecosystem, focused on communication ownership, independent hosting, and service control.
My portfolio platform for presenting networking work, infrastructure projects, self-hosted systems, and technical documentation in a way that reflects both field experience and long-term growth.
Structured deployment notes, runbooks, troubleshooting references, and operational documentation created to support switch installs, migration planning, and engineering consistency.
A bot project built around automated content gathering, feed-driven workflows, and hands-on deployment experience across hosted environments and iterative tool design.
An active study and lab track focused on strengthening routing, switching, VLANs, verification, and troubleshooting through structured Packet Tracer work and command-based practice.
Custom Linux systems built for productivity, terminal-driven workflows, virtualization, experimentation, and day-to-day technical project work.
Hands-on network deployment work involving physical switch stacking, installation support, troubleshooting, and repair across Cisco and Juniper environments.
A continuing progression into deeper Layer 3, infrastructure, self-hosting, and systems engineering work through field exposure, lab practice, and technical build projects.
