Projects
Home Cloud
Raspberry Pi - Casa OS 2025• Deployed a Raspberry Pi 5 using Debian Linux and installed Casa OS as the UI. Configured dual M.2 PCIe SSDs into a software RAID 1 for redundancy.
• Installed containerised applications within the home server to allow for media sharing from our devices, replacing the need for public cloud backups.
• Setup a VPN meshnet to allow for external access outside our home network. Added our devices to the meshnet and device can now be accessed publicly on an assigned meshnet IP by approved devices.
• Encountered multiple issues along the way such as RAID corruption and linux user permission issues. Extensive troubleshooting resolved all.
Cloud Resume Challenge
AWS 2025 (in progress)• Chose a simple static CV website (from a CodePen template) over JS frameworks, customized it with Font Awesome icons via a public CDN, organized CSS variables for consistency, added personal project experience, and exported it to host on AWS S3.
• Uploaded above to S3 for public accessibility, then worked through setting up CloudFront with HTTPS, DNS validation, ACM certs, and Route 53 domain registration, while troubleshooting origin naming, permissions, SSL cert validation, bucket naming conflicts, and DNS resolution issues.
• Created a new www subdomain S3 bucket, enabled public access, fixed a forbidden error by manually updating bucket permissions, then reconfigured Route 53 and CloudFront — resolved CNAME issues, making the HTTPS site live at https://www.dmcc-resume.com/.
