About Me
I am a technically motivated professional with hands-on experience in networking, cybersecurity fundamentals, and systems support. My background includes working in telecom provisioning environments where uptime, accuracy, and rapid incident resolution were critical.
I have a strong interest in enterprise networking, infrastructure security, and automation. I enjoy understanding how systems work end to end and improving them through better design, monitoring, and security practices. Alongside my professional experience, I continuously build projects and labs to strengthen my real-world skills.
I am currently pursuing a master's degree in computer science at Rowan University and complementing my education with industry certifications and practical projects.

Work Experience
Systems Engineer
- Supported Oracle ASAP telecom provisioning systems for ISP and CATV services in production environments
- Monitored and troubleshot provisioning failures, ensuring uninterrupted service delivery for critical network operations
- Handled failed and in-progress orders, performed system-level actions including server and JVM restarts
- Collaborated with L1 and NOC teams to resolve incidents efficiently, reducing mean time to resolution
- Conducted testing on network elements, documented issues and resolutions for knowledge base
- Improved system reliability by eliminating recurring downtime during critical periods through proactive monitoring
- Ensured data integrity and correct order states across production provisioning workflows
Projects & Labs
Dockerized Web Application with CI/CD
Built a complete web application deployment pipeline using Docker, Jenkins, and AWS. Focused on automating deployments, improving consistency, and reducing manual errors. Containerization helped stabilize the environment, while the CI/CD pipeline ensured faster and more reliable updates.
Mission Pumpkin - Vulnerable Web Application
Designed a deliberately vulnerable web application simulating real-world security risks based on OWASP Top 10. Performed reconnaissance and testing using tools like Nmap and Hydra, along with manual brute-force and exploitation techniques. Enhanced understanding of attack paths and secure application design.
Scalable Multi-City Enterprise Network
Designed and implemented a multi-city enterprise network connecting Glassboro, Gloucester, and Atlantic City using Frame Relay technology. Supported DHCP and DNS services for over 100 devices with centralized HTTP and FTP services. Focused on scalability, fault tolerance, and secure inter-site communication.
