The Guy Behind The Lab

I'm an IT professional with a degree in Networking Administration and a career spanning help desk leadership, AV event production, and systems infrastructure. I've spent my life living and breathing computers — from building home labs to launching the nation's first COVID-19 crisis call center under pressure.

Recently I've been diving deep into Web Development, blockchain technology, and DeFi automation on the Sui network. My home lab runs a Pi 5 as a NAS and web server, Pi-hole for network-wide ad blocking, and a growing cluster of Raspberry Pis I break and fix daily — which is exactly how I learn.

I believe the best way to understand technology is to build something, break it, and fix it yourself. Every project teaches more than any tutorial ever could.

Things I've Built

PROJECT_01

Sui Flash Loan Script

Built and deployed a flash loan arbitrage script on the Sui blockchain using Scallop Protocol. Borrows SUI, executes arbitrage logic across DEXes (Cetus, Turbos), and repays within a single atomic transaction.

PROJECT_02

Raspberry Pi Home Lab

Designed and built a multi-node home lab running Pi 5 as primary server with NAS (Samba), Pi-hole network ad blocking, Nginx web server, and a growing Pi cluster planned for Kubernetes (k3s).

PROJECT_03

This Portfolio Website

Designed and built from scratch using HTML, CSS and vanilla JavaScript. Hosted on a Raspberry Pi 5 running Nginx on my home network. No frameworks, no templates — written line by line as part of learning web development.

PROJECT_05

AI-Powered Dev Workflow

Built a local AI development environment using Claude Desktop with MCP tool integrations running via Docker on Windows 11. Uses AI agents to assist with coding, file management, research, and automation — turning solo projects into AI-assisted pipelines.

PROJECT_06

Raspberry Pi Litecoin Mining Farm

Built a networked Raspberry Pi 3 mining cluster using USB Moonlander ASICs. Configured open source mining software across multiple nodes, managed the network infrastructure, and optimized hashrate performance. Also deployed XMRig on a Pi to run a Monero node — just to see if it could be done. Also maintains and troubleshoots Bitmain Antminer ASIC miners.

PROJECT_04

COVID-19 Crisis Call Center

Spearheaded the launch of the nation's first COVID-19 crisis call center at Inktel. Designed workflow, created training materials, and deployed the entire operation under extreme time pressure at the start of the pandemic.
