Introduction
1 print("Kia ora koutou!")My name is Emilio Mardones, and I am based in Aotearoa, New Zealand. I recently completed a Level 7 Diploma in Network Engineering & Cloud Computing and am building my career at the intersection of cloud infrastructure, networking, and cybersecurity.
This portfolio documents my hands-on projects, labs, and research as I continue developing practical engineering skills. My work includes:
- Cloud infrastructure labs in Azure, with growing focus on OpenStack and Kubernetes.
- Network design, segmentation, and security hardening projects.
- Malware analysis and sandbox research.
- Python automation and IoT integrations.
- Packet capture and protocol analysis using Wireshark and tcpdump.
- Security reporting aligned with frameworks such as NIST and MITRE ATT&CK.
- Continuous learning through platforms such as TryHackMe and Hack The Box.
Career Goals
My long-term goal is to contribute to teams working in:
- Cloud Security / Security Operations.
- Cloud Engineering.
- Infrastructure / Platform Engineering.
- Network Engineering.
- IoT and M2M cloud deployment.
This page will continue to evolve as I publish new labs, projects, and research.
