Thomas Teixeira

Infrastructure architect focused on designing, deploying and documenting reliable, observable and secure platforms.

My work sits at the intersection of infrastructure architecture, Linux operations, automation and application delivery. Cybersecurity is an important engineering concern in these systems, but my primary focus is building infrastructure that is resilient, maintainable and reproducible.

Core Areas

  • Infrastructure architecture and platform design
  • Linux systems, networking and homelab operations
  • Infrastructure as code with Ansible
  • Container platforms and Docker Swarm
  • CI/CD, deployment automation and observability
  • Network segmentation, VPNs and secure service exposure
  • Full-stack platform integration and technical documentation

Selected Work

Project Focus
Quantum Motors Platform Infrastructure platform with Ansible, Docker Swarm, CI/CD and observability
EHomeShield Homelab Deployment Reproducible Linux and Raspberry Pi deployment automation
EHomeShield Security Gateway Network platform combining FastAPI, React, DNS, firewall and WireGuard workflows
Secure Multi-Site Network Architecture Infrastructure and network architecture with segmentation, DMZ and VPN design
Security Engineering DevSecOps Lab Security controls, CI validation and policy automation

Engineering Approach

I favor clear architecture, explicit operational boundaries, automation, observable services and documentation that enables another engineer to operate the platform safely.

Education

ETNA - infrastructure, networking, software engineering and cybersecurity.
