Projects & interactive lab

Explore browser-based networking and security demonstrations, followed by selected infrastructure, automation, and software projects. The project labels distinguish personal infrastructure, independent development, and academic work.

Explore My Lab

Step inside the infrastructure.

Explore a public-safe representation of my homelab: application and media/AI hosts, service inventory, an interactive infrastructure map, Bratsu SecureOps incident workflows, live isolated service checks, and the weather and KEV intelligence dashboard.

Live sandbox telemetry and public feeds are distinguished from simulated incidents and curated infrastructure records. No production accounts or network details are exposed.

Security Operations Platform

Bratsu SecureOps

An independent development project exploring managed IT and cybersecurity workflows for small businesses. I run it in production today as my own infrastructure monitoring platform, and the design brings together asset visibility, security findings, and guided remediation.

Managed endpointsSecureOps control planeEvidence & remediation
  • Developing workflows for asset context, findings, remediation guidance, and operational evidence.
  • Exploring AI-assisted guidance with reviewable actions and documented operational evidence.
  • Developed with secure deployment, maintainability, and small-business usability in mind.

Local Knowledge Tool

Context Window

A desktop app for capturing project context, reusable notes, and work history for reuse across infrastructure, code, and documentation tasks.

  • Next.js interface packaged with Electron for local use.
  • Focused on preserving context across long-running projects.
  • Useful for coding, incident notes, and career-material drafting.

Infrastructure Lab

Proxmox Homelab Infrastructure

I maintain a personal infrastructure environment with Proxmox, Debian, LXCs, Docker, reverse proxying, DNS, VPN access, monitoring, AI services, and media automation. I use it to investigate service failures, test configuration changes, and practice recovery procedures.

  • Services are treated as living systems with uptime, access, backup, and recovery concerns.
  • Monitoring and automation projects are tested against real hosts and containers.
  • Security choices are grounded in access control, segmentation, update paths, and logging.

Desktop Utility

Class Instruction Condenser

A local Tkinter app that turns long assignment instructions into clear task briefs. It organizes deliverables, requirements, and grading criteria into a concise task brief.

  • Built with Python, Tkinter, tests, and a packaged Windows executable.
  • Separates deliverables, constraints, and submission requirements.
  • Designed for private local use rather than sending coursework to a cloud service.

Automation Workflow

Media Update Broadcaster

A Python workflow for turning media-stack update activity into clear Discord-ready messages. It focuses on useful summaries, structured configuration, and logs that make the automation easy to trust.

  • Fetches and formats update information for family-readable notifications.
  • Uses reusable configuration and a history file to avoid noisy repeats.
  • Built with deployment in mind for lightweight homelab hosting.
