About

Security-first.
Hands-on by default.

I'm a cybersecurity professional with a B.S. in Cybersecurity and a background in data-driven operations. I bring real hands-on infrastructure, troubleshooting, and automation experience — and I'm actively pursuing IT support and security roles.

I run a self-hosted homelab — Nimbus — on a Synology DS224+ NAS. Docker containers, n8n automation workflows, Cloudflare Zero Trust tunnels. I'd rather build and break things than read about them.

Currently grinding through CompTIA Security+ using an AI-powered quiz system I built myself: Whisper transcripts, Gemini AI quiz generation, Telegram delivery, and Postgres/Notion score tracking. A custom tool that actually works — and keeps working.

What I work with.

Academic foundation reinforced by real-world practice — building and securing my own infrastructure from the ground up.

Projects

Built,
not borrowed.

Personal projects that reflect how I actually think about security — from infrastructure up.

01
Homelab Infrastructure
Self-Hosted Security Lab
Designed and secured a production homelab on a Synology NAS running Docker-containerized services behind a Cloudflare Zero Trust tunnel — no open ports, no exposed attack surface. Conducted a full privilege audit across all containers: removed root access, migrated hardcoded credentials to environment variables, and enforced least-privilege across the stack.

02
Automation Engineering
Security+ AI Study System
Built a fully automated study pipeline from scratch: transcribed 121 Professor Messer videos using Whisper AI, then wired n8n to generate domain-targeted quiz questions via Gemini, deliver them daily through a Telegram bot, and log scores to both Postgres and Notion. Cross-workflow state sharing, custom filter tags, and answer distribution tuning — engineered end to end.

03
Portfolio & Infrastructure
SudoJo.dev — This Site
Designed and hand-coded this portfolio from scratch — no templates, no site builders. Self-hosted on a containerized nginx instance, served through a named Cloudflare tunnel to a custom domain. DNS routing, SSL termination at the edge, and zero open firewall ports. The site you're looking at is running on my homelab right now.

The roadmap.

A deliberate progression toward cloud security engineering — each cert building on the last.

Let's connect.

Open to opportunities.

I'm actively seeking entry-level cybersecurity roles — and open to IT support positions where I can build hands-on experience on the path toward security engineering.

If you're building a security-conscious team and want someone who builds their own tools and doesn't stop until things work — let's talk.
