Cybersecurity & Defensive Systems
Hardening, attack-surface reduction, trust boundaries, access control, validation, and defensive decisions tied to how the underlying system actually operates.
Technical Skills
Skills are grouped by what I can actually build, troubleshoot, secure, and document — with project evidence attached.
Proof Over Percentages
This page avoids arbitrary proficiency bars. Each area connects tools and concepts to projects, writeups, or systems where they were actually used.
Core Capability
Hardening, attack-surface reduction, trust boundaries, access control, validation, and defensive decisions tied to how the underlying system actually operates.
Linux workstation and server administration, services, package management, permissions, self-hosting, troubleshooting, recovery, and maintainable day-to-day operation.
Network architecture, DNS, firewall intent, routing concepts, segmentation, validation, and troubleshooting with explicit trust boundaries.
Building interfaces, application logic, technical tooling, deployment workflows, data-driven systems, and version-controlled software with explicit ownership and validation.
Reducing repetitive work with scripts, command-line tooling, reusable processes, structured workflows, CI checks, and technical integrations.
Using generative AI and local language models for development, debugging, architecture review, technical analysis, structured planning, model evaluation, and automation.
Tools & Platforms
Tools change. The transferable part is understanding the system around them.
Evidence
The case studies and writeups show how these skills are used, where things failed, and what changed afterward.
