Areas of Technical Practice
Practical domains of expertise where I design, configure, and troubleshoot network and system infrastructure.
Enterprise Network Architecture & Design
Designing structured Layer 2 and Layer 3 network topologies tailored for branch offices and multi-subnet corporate environments.
- VLAN segmentation and 802.1Q trunking layouts
- OSPF multi-area routing and route summarization
- Redundant default gateway configurations
- IPv4/IPv6 address hierarchy and allocation schemes
Linux Server Deployment & Hardening
Deploying and configuring reliable Linux servers with security-first operational standards.
- Ubuntu / Debian production installation and hardening
- Nginx reverse proxy and SSL/TLS automation
- SSH bastion configurations and key-based enforcement
- UFW and iptables packet filtering configurations
DNS Architecture & Web Delivery
Connecting domains with resilient authoritative DNS setups and high-speed edge delivery platforms.
- Authoritative Anycast DNS zone management
- A, AAAA, CNAME, MX, and TXT record optimization
- Automated SSL certificate provisioning and HTTPS enforcement
- Serverless edge static site deployment via GitHub Pages
Infrastructure Telemetry & Diagnostic Support
Proactive health tracking, device unbinding/management, and structured troubleshooting methodology.
- CCTV and hardware device management (Hik-Partner Pro)
- Automated endpoint and ping heartbeat probes
- Diagnostic packet trace inspection and route isolation
- Thorough network documentation and topology diagrams
Enterprise, Campus & Municipal Infrastructure
Turnkey internal network design and deployment engineered specifically for educational campuses (schools, colleges), corporate business houses, and municipal/metropolitan local government offices.
- High-density school and college Wi-Fi & computer lab networks
- Corporate business house multi-floor structured LAN distribution
- Municipality and metropolitan e-Governance data center & ward connectivity
- Redundant campus core switching rings and fiber distribution backbones
SD-WAN, Network Separation & Zero-Trust Isolation
Connecting distributed branches with intelligent SD-WAN overlays while enforcing strict internal micro-segmentation to isolate critical data from guest and untrusted endpoints.
- Multi-branch SD-WAN (Fortinet Secure SD-WAN, Cisco, MikroTik) with auto-failover
- VRF-Lite and 802.1Q VLAN separation across administrative, financial, and student zones
- Private VLANs (PVLANs) preventing lateral movement across workstations and labs
- 802.1X NAC, isolated Guest Wi-Fi captive portals, and CCTV/IoT physical containment
