PROJECTS

Sept 2025 – Present

Enterprise Network Lab

STP, DHCP, EIGRP, RIP, Wireshark, Wireless, VLANs

•Built fault-tolerant Cisco enterprise networks with VLANs, trunking, STP/RSTP, and HSRP for redundancy
•Configured wireless LANs, DHCP, NAT/PAT, and inter-VLAN routing for Internet and internal connectivity
•Implemented RIP, EIGRP, and OSPF multi-area routing with redistribution and convergence tuning
•Validated network behavior using Wireshark, ping/trace, and IOS tools for routing and failover

Fall 2025

Advanced Enterprise Networks

OSPF, RSVP-TE, MPLS, IPsec, NAT, IPv6

•Designed multi-site enterprise and ISP-style networks with MPLS and RSVP-TE tunnels and bandwidth guarantees
•Integrated IPv4/IPv6 connectivity with IPsec-encrypted tunnels and OSPFv2/v3 routing
•Configured NAT, stateful NAT, and IPv4–IPv6 translation (NAT-PT) where required
•Ensured fault tolerance, redundancy, and secure communication across multiple sites

Sept 2025 – Present

Network Applications

C++, Network Programming

•Built a multi-threaded TCP/UDP HTTP web server and HTTP caching proxy in C/C++ with request parsing and hostname validation
•Implemented persistent connections, pipelining, MD5-based page caching, and reliable UDP transfers (Stop-and-Wait, Go-Back-N)
•Added concurrent request processing via threading/forking, background prefetching, and MD5 hash-based caching
•Developed a DFS in C with chunking, redundancy, and client/server commands (list/get/put)

Sept 2025 – Present

Home Lab

Linux, Virtualization, WireGuard, Docker, Cloudflare

•Maintain a home lab (https://index.dheerajg.me) hosting multiple services with WireGuard access and Docker-based deployments
•Use backups and virtualization to ensure redundancy and safe experimentation
