Building scalable infrastructure and intelligent automation solutions
About Me
I'm a Computer Science student at The University of Texas at Arlington with a passion for building robust systems and solving complex problems through code. Currently maintaining a 3.53 GPA while pursuing my degree, I bring hands-on experience from deploying enterprise infrastructure, automating workflows, and securing production environments.
My technical journey spans from low-level system administration, managing virtualized servers, implementing security hardening, and configuring network infrastructure, to high-level software development with Python, Java, and JavaScript. Whether I'm deploying VPN solutions on VMware, automating document processing pipelines, or building web applications, I focus on creating solutions that are both technically sound and practically valuable.
Currently seeking Summer 2026 internship opportunities where I can contribute to meaningful projects, continue learning from experienced engineers, and apply my skills in systems engineering, software development, or cloud infrastructure.

Featured Projects
Enterprise Virtualization Infrastructure
A production-grade virtualized server environment supporting departmental operations at Campbellsville University. The infrastructure hosts 8+ Ubuntu Server virtual machines running critical services including web servers, databases, and application platforms.
The Challenge
The department needed a reliable, scalable server infrastructure that could handle multiple services while maintaining security compliance and minimizing hardware costs.
My Solution
Architected and deployed a complete virtualization stack using Proxmox VE on Dell PowerEdge hardware with RAID-1 storage redundancy. Implemented comprehensive security hardening including UFW firewall configurations, SSH key-based authentication with Ed25519 cryptography, and CIS Level 1 benchmark compliance across all production VMs.
- Configured Apache web server and MySQL database following OWASP security best practices
- Developed automated Bash scripts for system maintenance, monitoring, and backup procedures
- Created 30+ pages of technical documentation covering network topology, security protocols, and incident response procedures
- Achieved zero unplanned downtime since deployment

Enterprise VPN & Microsoft 365 Migration
A complete enterprise technology transformation project involving VPN infrastructure deployment and organization-wide migration from Google Workspace to Microsoft 365 ecosystem.
The Challenge
Tecniequipos S.A. needed secure remote access for distributed teams and wanted to consolidate their productivity suite into Microsoft 365 for better integration and compliance.
My Solution
VPN Deployment: Architected and deployed SoftEther VPN on VMware virtualized infrastructure with SSL-VPN protocol and certificate-based authentication, enabling secure remote access for entire organization.
M365 Migration: Led end-to-end migration from Google Workspace to Microsoft 365, including Exchange Online email configuration, SharePoint site architecture, OneDrive deployment, and Azure AD user synchronization—all executed with zero production downtime.
- Configured SSL-VPN with PKI certificate authentication for enhanced security
- Implemented Azure AD synchronization and user provisioning automation
- Designed SharePoint site structure aligned with organizational workflows
- Created migration runbooks and provided end-user training
- Successfully migrated 100% of users with no data loss or service interruption

Document Processing Automation System
An intelligent document management system that automatically processes, categorizes, and indexes legal documents using OCR and metadata extraction, transforming manual workflows into streamlined digital processes.
The Challenge
A legal consulting firm was spending 15 minutes per document on manual data entry, categorization, and filing—bottlenecking their operations when dealing with 600+ documents.
My Solution
Built a Python automation pipeline that leverages OCR technology to extract text from scanned documents, applies intelligent categorization algorithms based on document content, and automatically generates structured metadata for searchable indexing.
- Implemented OCR processing with accuracy validation and error handling
- Designed metadata extraction logic to identify document types, dates, parties, and key terms
- Created automated categorization system that routes documents to appropriate digital repositories
- Built robust error handling and logging for production reliability
