About Me

Hello! I’m an I.T. Systems Administrator and former U.S. Army Signal Specialist with over a decade of experience in networking, systems management, and secure communications. I've worked with a broad set of technologies, continually expanding my expertise to become a well-rounded IT professional. Driven by a problem-solving mindset and a commitment to innovation, I’m passionate about building resilient solutions that adapt to evolving needs and effectively tackle complex challenges.

Featured Projects

Project 1

Automated Backup Solution

Built a custom automated cloud backup solution for a local business using AWS S3 and Python scripts to monitor changes on their on-premises server. The scripts detected and uploaded only new or modified data, optimizing AWS storage costs by minimizing data transfer. Leveraged AWS KMS for server-side encryption at rest and SSL/TLS for encryption in transit, ensuring secure, efficient backups that met the client’s need for cost-effective, off-site redundancy.

Project 2

Labor Management System

Developed and implemented an on-premises web application to streamline tracking of employee productivity and activity metrics. Previously, employees could only clock in and out at shift start and end, limiting operational insights. Using a LAMP stack, I built a system compatible with both mobile scanners and desktop workstations, allowing employees to log time against specific business units and tasks. This application captures real-time data on productivity, activity flow, and efficiency across the warehouse. The resulting data now supports seasonal workload forecasting and enables accurate project quotes based on historical project metrics.
