About

Suraj built his technical foundation independent of a formal CS degree — through certification, lab work, and shipped projects. He has designed two enterprise-grade network topologies in Cisco Packet Tracer covering hierarchical Core/Distribution/Access architecture, OSPF and RIPv2 routing, VLAN segmentation, and secure remote management. Alongside networking, he administers Red Hat Linux systems and deploys AWS cloud infrastructure end to end.

He also built and shipped Dork Engine, a live security reconnaissance tool used by real researchers and bug bounty hunters — proof that his skills hold up outside the lab.

Projects

Company Network Design & Implementation
Cisco Packet Tracer · Advanced
  • Designed a redundant enterprise topology using hierarchical Core, Distribution, and Access layers across Sales & Marketing, HR & Logistics, Finance & Accounts, Admin & PR, ICT, and a dedicated Server Room.
  • Deployed OSPF as the primary routing protocol alongside a dedicated DHCP server for dynamic IP assignment.
  • Implemented Port Security (sticky MACs) for the finance department, SSH for secure remote device management, and NAT Overload/PAT for multi-ISP connectivity.

Campus Network Design & Implementation
Cisco Packet Tracer · Intermediate
  • Built a multi-site campus topology with Core, Distribution, and Access layers using multi-layer switches, connecting a Main Campus and Branch Campus.
  • Created department-based VLANs (Admin, HR, Finance, Business, Engineering, Arts & Design, IT) with inter-VLAN routing via router-on-a-stick sub-interfaces.
  • Deployed router-based DHCP server pools across all faculty and student labs, and implemented RIPv2 for internal routing between campuses.
  • Integrated a cloud-based email server using static routing and validated end-to-end connectivity.

  • Built and deployed a responsive web application that automates Google Dorking for security reconnaissance, used by security researchers and bug bounty hunters.
  • Engineered dynamic query generation across 60+ categorized dork types, covering exposed databases, API keys, and cloud storage buckets (S3, Firebase, Azure, GCP).
  • Integrated third-party OSINT lookups (Shodan, Censys, GitHub, Wayback Machine, crt.sh) to extend reconnaissance beyond standard Google search.
