Project Portfolio

A detailed look at my technical implementations and infrastructure projects.

Office Network Infrastructure Setup

Designed and deployed a complete local area network (LAN) for a new office site. This involved planning the network topology, configuring core networking equipment, and ensuring secure and efficient connectivity for all staff members.

Key Responsibilities

  • Designed network topology including VLAN segmentation for different departments.
  • Configured MikroTik routers for load balancing and failover.
  • Deployed Ubiquiti Unifi Access Points for seamless Wi-Fi coverage.
  • Implemented DHCP and DNS servers for efficient address management.
  • Set up VPN access for remote workers to securely connect to the office network.
  • Conducted cable management and termination for structured cabling.

Enterprise CCTV Surveillance Deployment

Led the installation and configuration of a comprehensive IP-based CCTV system for a large facility. The project focused on high-availability recording, remote monitoring capabilities, and integration with existing network infrastructure.

Key Responsibilities

  • Installed 50+ IP Cameras (Hikvision & Dahua) across critical monitoring points.
  • Configured NVRs (Network Video Recorders) for 24/7 recording with RAID storage.
  • Set up remote viewing access via mobile apps and desktop clients (SmartPSS).
  • Implemented separate VLAN for CCTV traffic to prevent network congestion.
  • Troubleshot camera connectivity issues in challenging physical environments.
  • Provided training to security staff on system operation and footage retrieval.

Self-Hosted Metabase & No-Code Platform

Deployed a robust self-hosted data analytics and application development environment on a VPS. This solution enabled the company to visualize data with Metabase and build custom internal tools using NocoBase, all running securely in Docker containers with custom subdomains.

Key Responsibilities

  • Provisioned and secured a Linux VPS (Virtual Private Server) for hosting services.
  • Implemented Docker and Docker Compose to containerize Metabase and NocoBase applications.
  • Configured Nginx Proxy Manager to handle reverse proxying and SSL termination.
  • Set up custom subdomains (e.g., analytics.company.com, app.company.com) for easy access.
  • Managed DNS records to point subdomains to the VPS IP address.
  • Established automated backup routines for Docker volumes and databases.
