I’m a Network Engineer with a strong foundation in enterprise networking, infrastructure operations, and systems administration, focused on building reliable, secure, and scalable network environments. I have hands-on experience designing and operating end-to-end network solutions across on-prem and cloud platforms, with a solid understanding of routing, switching, high availability, WAN connectivity, and network services.

Beyond networking, I work comfortably with Linux and Windows Server environments, cloud networking on Microsoft Azure, and virtualization platforms, and I regularly build real-world labs to validate designs before deployment. I place strong emphasis on monitoring, observability, documentation, and structured troubleshooting, aiming to deliver networks that are not only functional, but resilient, well-documented, and easy to operate at scale.

Projects

Networking Tools Collection

Created a collection of 20+ web-based networking tools. From Subnetting, VLSM, IPv6, and Route Summarization to advanced BGP, STP, QoS, and MTU calculations, every tool is designed to be accurate, intuitive, and practical for real-world use. Security-focused utilities like ACL generators, VPN configuration helpers, password tools, and hash generators help streamline secure deployments, while reference tools such as Port lookups, MAC vendor search, SNMP OID lookup, and protocol decoders make troubleshooting faster and easier.

SD-WAN Implementation

I have deployed and validated complex Cisco SD-WAN fabrics across virtual and cloud platforms. To solve the repetitive task of initial device provisioning, I engineered a web-based tool that generates ready-to-use configuration files from form input, dramatically streamlining the setup of vEdges and vManage.

Cloud Monitoring and Operations

I architected and maintain a comprehensive monitoring stack on Azure to ensure the performance and availability of my public-facing projects. The system leverages LibreNMS on a dedicated VM for infrastructure and network monitoring, while New Relic provides deep application performance insights for web services deployed in Docker containers on a separate host. This containerized environment uses an Nginx reverse proxy to securely manage and route traffic to the multiple internal applications and tools.

ACL & Firewall Rule Simulator

A comprehensive multi-platform Cisco ACL parser and simulator supporting IOS, IOS-XE, IOS-XR, ASA, and NX-OS platforms. Includes advanced features like IPv6 ACLs, object groups, time ranges, reflexive ACLs, and shadowed rule detection. Provides real-time syntax highlighting, validation, and detailed step-by-step packet simulation with human-readable explanations of how packets are evaluated against ACL rules.

Enterprise Network Lab with NAC & AD Integration

Designed and implemented a comprehensive enterprise campus network lab featuring PacketFence NAC for guest authentication and Windows Active Directory integration. Built on EVE-NG with VMware virtualization, the topology includes redundant Cisco infrastructure, VLAN segmentation, and secure role-based network access controls, demonstrating end-to-end enterprise networking and security implementation.

Network Automation with Ansible & Python

Full-stack network automation platform using Ansible & Python for virtual Cisco device management. Features FastAPI dashboard with Prometheus monitoring and containerized CI/CD pipeline. Implements enterprise practices without physical hardware through PyATS testing and infrastructure-as-code workflows.

Portfolio Website

Built a responsive and visually engaging portfolio website using HTML, CSS, JavaScript, and GSAP, featuring animated transitions and interactive components. The site highlights technical projects, skills, and professional experience, with an emphasis on performance optimization and modern front-end best practices.

Hybrid Cloud Network Lab

Designed and implemented a complete hybrid cloud networking lab that bridges traditional network engineering with modern cloud infrastructure. This project demonstrates practical expertise in connecting physical/virtual on-premises environments to Azure cloud services using industry-standard protocols and security practices.
