Build. Integrate. Learn. Share.

A public engineering lab for real infrastructure and cybersecurity work — deployments, integrations, experiments and practical notes built from systems I operate, troubleshoot and improve.

man twb.dev — what lives here

An engineering notebook that happens to be public.

01

Cybersecurity integration

SIEM, incident response, threat intelligence, identity security and the glue between security tools.

02

Infrastructure engineering

Linux, Proxmox VE, containers, networking, reverse proxies, storage, backup and hybrid environments.

03

Labs & experiments

Hands-on evaluation of open-source and commercial technologies before they become operational solutions.

04

How-tos & field notes

Practical notes distilled from troubleshooting, migrations, implementations and my existing Obsidian knowledge base.

05

Automation

PowerShell, Bash, n8n and small tools that remove repetitive infrastructure and security work.

06

Public source

Selected original projects and sanitized integrations published through GitHub when they are useful to others.

$ find ~/labs -maxdepth 2 -type project

Current labs and engineering projects.

labs/crucix featured lab

Crucix OSINT intelligence integration

Private deployment of the open-source Crucix platform. The lab explores how external intelligence can be combined with infrastructure telemetry and security tooling. Runtime access remains private while the integration is designed safely.

projects/wazuh-siem in progress

Wazuh SIEM integration

Building operational SIEM alerting and integrations around Wazuh, with Telegram first and TheHive as the incident-response path.

projects/m365-security implemented

Microsoft 365 identity security

Conditional Access, MFA strategy, sign-in analysis and security hardening for hybrid Microsoft identity environments.

projects/observability operational

Infrastructure observability stack

Graylog, Grafana, Prometheus, InfluxDB and related telemetry used together to understand what infrastructure is actually doing.

$ cat /etc/lab-purpose

Projects show what was built. Knowledge explains how.

Tech.Wired.Brains.dev is deliberately separate from the professional portfolio. The .com explains who I am and the work I have delivered; this site is where the engineering becomes visible.

The first focus is cybersecurity and infrastructure integration: connecting telemetry, security operations, networking, identity, observability and external intelligence into systems that are useful in practice.

  • >Never publish secrets, private addressing or client-sensitive data.
  • >Credit upstream projects; document my deployment and integration work separately.
  • >Prefer reproducible configurations over screenshots of success.
  • >A failed experiment is still useful when the reason is documented.
  • >Security and maintainability are part of the architecture, not add-ons.
