Featured Projects
WasteCoin Backend
Developed backend services for WasteCoin platform, including user authentication with JWT & bcrypt, RESTful API design, and MongoDB database integration.
Smart Contract Development
Developed and tested smart contracts using Solidity on Hardhat framework. Explored dApp development and blockchain integration with ethers.js.
Enterprise Network Simulation
Designed and simulated enterprise network topologies using GNS3 & Cisco Packet Tracer, covering VLANs, routing protocols, firewall rules, and VPN configurations.
Single Cycle MIPS CPU Design
Designed and implemented a Single Cycle MIPS CPU. Tested instruction execution and memory operations.
Home Lab Infrastructure
Built an enterprise-grade home lab using Proxmox VE. Deployed a Windows Server 2022 Domain Controller for Active Directory (AD DS, DNS, DHCP, GPOs), implemented a virtual pfSense firewall with VLAN segmentation, configured a standalone WireGuard remote access VPN server on Ubuntu, and built a 3-router OSPF/BGP topology using FRRouting to demonstrate dynamic routing protocols in production software.
Portfolio Website
Developed and deployed a personal portfolio. Configured Cloudflare DNS and Vercel deployment.
// homelab
HomeLab Sprint
Self-built infrastructure project — Building enterprise-level systems from scratch.
Active Directory Infrastructure
Set up a small-scale enterprise network using Proxmox VE as hypervisor with Windows Server 2022 Domain Controller managing centralized authentication, DNS, DHCP, and Group Policy.
pfSense Firewall + VLAN Segmentation
Implemented a virtual firewall/router with WAN/LAN separation, outbound NAT, and VLAN-based network segmentation using pfSense CE on Proxmox VE.
WireGuard Remote Access VPN
Set up a WireGuard VPN server on Ubuntu VM with router port forwarding, enabling a Windows client to establish a full-tunnel VPN connection from outside the home network (tested over mobile data).
OSPF Routing Lab (FRRouting)
Built a 3-router OSPF topology on Proxmox VE using FRRouting — a production-grade routing suite — to demonstrate dynamic route learning, neighbor adjacency, and failure detection without any static routes.
BGP Routing Lab (FRRouting)
Reconfigured the OSPF lab topology into three separate Autonomous Systems (AS 65001–65003) and established eBGP sessions using FRRouting to demonstrate AS-Path propagation, transit routing, and RFC 8212 default policy behavior.
pfSense → Wazuh SIEM Integration
Built a full syslog-based log pipeline from pfSense firewall into Wazuh SIEM/XDR. Wrote custom decoders and detection rules to parse pfSense filterlog, generate real-time alerts (including port-scan detection via MITRE T1046), and built a firewall monitoring dashboard in OpenSearch Dashboards.
Docker + Nginx Portfolio Deployment
Containerizing and deploying the portfolio website using Docker and Nginx as a reverse proxy.
Monitoring Lab (Prometheus + Grafana)
Setting up infrastructure monitoring with Prometheus metrics collection and Grafana dashboards.
ELK Stack + Wazuh SIEM
Deploying a SIEM solution with Elasticsearch, Logstash, Kibana, and Wazuh for centralized log collection and security monitoring.
VMware ESXi vs Proxmox Comparison
Hands-on comparison of VMware ESXi and Proxmox VE hypervisors covering installation, VM management, and enterprise features.
