πŸ‘¨πŸΎβ€πŸ’» About Me

I'm an IT professional building toward a career in AWS cloud infrastructure, enterprise networking, and cybersecurity operations, with hands-on lab experience across identity, networking, and security tooling.

My focus is the modern cloud and network stack: AWS core services, IAM, VPC architecture, enterprise routing and switching, infrastructure-as-code, and network automation. I pair that with foundational skills in Active Directory, Windows Server, Linux, and SIEM workflows so I can operate effectively in the hybrid environments most enterprises actually run.

I'm executing a structured certification roadmap β€” Network+ β†’ CCNA β†’ AWS Solutions Architect Associate β†’ Cisco DevNet β€” alongside an Electrical Diploma at Atlanta Technical College. That combination positions me for cloud, network engineering, and data center infrastructure roles where physical infrastructure, enterprise networking, and cloud operations meet.

I build, document, and ship β€” every project in this portfolio reflects a working system, not theory.

πŸš€ Featured Projects

☁️ AWS Cloud Infrastructure

AWS Three-Tier VPC Architecture (in progress)

Designing and deploying a production-style VPC with public, private, and database subnets across multiple availability zones β€” the foundational pattern behind most real-world AWS workloads.

  • Stack: AWS VPC Β· EC2 Β· IAM Β· Security Groups Β· NACLs Β· Route 53 Β· CloudWatch
  • Skills Demonstrated: Cloud network architecture Β· Least-privilege IAM design Β· High availability Β· AWS CLI automation
  • Business Relevance: Replicates the exact architecture enterprises deploy for web-tier workloads β€” a baseline competency for any AWS cloud support, operations, or security role.

πŸ“‚ Repository launching alongside AWS Solutions Architect Associate prep


AWS IAM & Identity Hardening Lab (planned)

A hands-on study of AWS Identity and Access Management: building role-based access patterns, MFA enforcement, permission boundaries, and CloudTrail-driven audit visibility.

  • Stack: AWS IAM Β· CloudTrail Β· CloudWatch Β· AWS Organizations Β· AWS CLI
  • Skills Demonstrated: Cloud identity management Β· Least-privilege design Β· Audit logging Β· Compliance evidence collection
  • Business Relevance: IAM misconfigurations remain one of the top sources of cloud breaches β€” this lab directly addresses the controls auditors and security teams actually care about.

🌐 Enterprise Networking (building toward CCNA)

Cisco Routing & Switching Lab (planned)

A multi-site enterprise topology built in Cisco Packet Tracer and GNS3, covering VLANs, inter-VLAN routing, OSPF, access control lists, and basic network automation with Python.

  • Stack: Cisco IOS Β· Packet Tracer Β· GNS3 Β· Python Β· Netmiko
  • Skills Demonstrated: Routing & switching Β· VLAN segmentation Β· ACL design Β· Network troubleshooting Β· Automation fundamentals
  • Business Relevance: Mirrors the day-one responsibilities of a network engineer or NOC technician β€” and the automation layer bridges directly into the DevNet skill set.

πŸ›‘οΈ Cybersecurity & Security Engineering

COGNISEC β€” AI-Enhanced Vulnerability Scanner

A modular security scanning toolkit that pairs traditional reconnaissance techniques with LLM-driven analysis to triage findings, reduce false positives, and produce human-readable remediation guidance.

  • Stack: Python Β· LLM APIs Β· Linux Β· Nmap-style reconnaissance
  • Skills Demonstrated: Vulnerability assessment Β· Security tool development Β· AI integration Β· Reporting automation
  • Business Relevance: Reduces analyst fatigue by automating low-value triage and surfacing the findings that actually matter β€” a real SOC pain point.

πŸ“‚ Repositories:


GRC Assessment β€” COGNISEC Risk Documentation

A governance, risk, and compliance walkthrough applied to the COGNISEC toolkit: documenting controls, risk acceptance, data handling, and mapping to recognized frameworks.

  • Stack: NIST CSF Β· NIST 800-53 mapping Β· Risk register methodology
  • Skills Demonstrated: GRC documentation Β· Risk assessment Β· Control mapping Β· Policy authoring
  • Business Relevance: Demonstrates the ability to bridge technical security work and the audit/compliance language that regulated industries require.

πŸ”§ Hybrid Infrastructure & Identity

Active Directory Domain Services on Cloud Infrastructure

Deployed a Windows Server domain controller on cloud-hosted VMs, joined client machines to the domain, and managed users, OUs, and Group Policy at scale β€” the foundation of hybrid identity in modern enterprises.

  • Stack: Cloud VMs Β· Windows Server Β· Active Directory Domain Services Β· Group Policy Β· DNS
  • Skills Demonstrated: Identity management Β· Hybrid cloud architecture Β· Domain administration Β· User provisioning
  • Business Relevance: Mirrors the exact workload most enterprises run during cloud migration β€” directly transferable to AWS Directory Service and AWS Managed Microsoft AD environments.

Cloud Network Security & Protocol Analysis

Configured cloud-native firewall rules to control inbound and outbound traffic, then captured and analyzed protocol behavior (ICMP, SSH, RDP, DNS) using Wireshark to validate enforcement.

  • Stack: Cloud Security Groups Β· Wireshark Β· TCP/IP Β· Linux Β· Windows
  • Skills Demonstrated: Cloud network security Β· Firewall rule design Β· Packet analysis Β· Protocol troubleshooting
  • Business Relevance: The principles map directly to AWS Security Groups and NACLs β€” a core competency for any AWS cloud support or security role.

🎫 IT Support & Service Management

osTicket β€” Enterprise Help Desk Deployment

End-to-end deployment of a production-style ticketing platform, including infrastructure prerequisites, role-based configuration, SLA design, and full ticket lifecycle walkthroughs.

  • Stack: osTicket Β· IIS Β· MySQL Β· PHP Β· Windows Server
  • Skills Demonstrated: Help desk operations Β· SLA configuration Β· Ticket triage workflows Β· End-user support documentation
  • Business Relevance: Directly applicable to Tier 1 / Tier 2 IT support roles and reflects ITIL-aligned service management principles.

πŸ“œ Certification Roadmap

A structured 24-month path from networking fundamentals to cloud automation:

Certification Status Target
CompTIA Network+ 🟑 In Progress June 2026
Cisco Certified Network Associate (CCNA) 🟑 In Progress September 2026
AWS Certified Solutions Architect – Associate 🟑 In Progress December 2026
Cisco Certified DevNet Associate βšͺ Planned June 2027

Why this path: Each certification builds on the last β€” Network+ establishes vendor-neutral fundamentals, CCNA proves enterprise networking depth, AWS SAA translates those fundamentals into cloud architecture, and DevNet closes the loop with automation and programmability. The result is a profile that maps cleanly to cloud network engineer, network automation engineer, and cloud infrastructure roles.


πŸŽ“ Education

  • Atlanta Technical College β€” Diploma, Electrical Systems (in progress)
  • Self-directed study β€” AWS cloud architecture, enterprise networking, cybersecurity

🎯 Mission

To grow into a cloud network engineer and automation specialist who can design, defend, and operate modern hybrid environments end-to-end β€” from the routing layer to the cloud edge β€” while building tools and automation that make infrastructure operations measurably more efficient.

I'm focused on doing the work that compounds: real labs, real documentation, real shipping.
