πŸ‘‹πŸΎ Hey, I'm Osasu

I'm a technologist moving into infrastructure engineering and cybersecurity, with a growing focus on securing AI infrastructure. My background spans web development and IT support, and I'm building toward roles in cloud security, platform engineering, and security operations. I think about systems holistically: how they connect, how they fail, and how to make them observable and defensible.

I currently work in IT Support while completing the TKH Innovation Fellowship 2026 (cybersecurity cohort, graduating September 2026), where I'm in Phase 2 working through cloud networking and AWS VPC design. Alongside the fellowship I run a self-hosted homelab on Proxmox where I build, break, monitor, and now host local AI models.


πŸ” Focus Areas

  • πŸ›‘οΈ Security Operations: SIEM, IDS/IPS, alert triage, incident response
  • ☁️ Cloud Security: AWS & Azure architecture, IAM, VPC design, GuardDuty, Security Hub
  • πŸ€– AI Infrastructure Security: self-hosted LLM deployment, hybrid local-to-cloud routing, prompt-injection testing, non-human identity (NHI) and MCP security
  • πŸ–₯️ Linux & Infrastructure: system administration, hardening, scripting
  • 🌐 Networking: OSI model, TCP/IP, subnetting, CIDR, DNS, packet analysis
  • πŸ”§ DevSecOps: Docker, Kubernetes, Terraform, CI/CD pipeline security
  • βš™οΈ Automation: Python and Bash scripting for security and ops workflows

πŸ§ͺ Currently Building

SOC & detection:

  • SOC homelab: Wazuh + Suricata + Zeek + Grafana + TheHive + Shuffle (SOAR) on Proxmox VMs and LXCs
  • Detection engineering: custom Suricata rules, ATT&CK-mapped alerts, Atomic Red Team simulations
  • Cloud security: secure auth architecture on AWS and Azure with IAM least privilege, WAF, and GuardDuty

Foundations:

  • OverTheWire Bandit for Linux command fluency, plus Python through hands-on scripting projects
