Projects

AWS Homelab

A low-cost AWS lab with a custom VPC, a public subnet holding a bastion host, and a private subnet whose server is reachable only through that bastion. I used least-privilege security groups, SSH key authentication, and a hardened SSH configuration, and installed Nginx on Amazon Linux. A monthly budget alert keeps costs in check, and the README includes a troubleshooting log. Next up: Windows Server with Active Directory, DNS, and DHCP, plus monitoring and Terraform.

NXTPSP

Ghostwriterv2

A generative AI writing platform built with Flask and Python, with Stripe billing and cloud deployment on Render.

Cafe-REST-API

A Python REST API that lets users access and manage a database of cafe records.

More Python work is in PythonProjects and on GitHub.
