● Independently discovered and disclosed multiple IDOR (Insecure Direct Object Reference) vulnerabilities across various platforms.

EXPERIENCE

Network Engineering Apprentice · University of Maine · 2024

● Co-designed a coreless BGP network using public IPv6 addresses tunneled over WireGuard, eliminating the need for a central routing core.

● Implemented IS-IS with OSPF to maintain full network-state awareness, suppressing broadcast traffic across all nodes.

● Built a Layer 2 switching plane encapsulated with EoIP and switched on MPLS labels, in collaboration with a senior network engineer.

Infrastructure Engineer · Independent · 2022 – Present

● Designed and deployed a self-hosted infrastructure stack using NixOS: reproducible, declarative provisioning in place of ad hoc Docker workflows.

● Provisioned Git servers, Nix packages, and NixOS modules to streamline patch application and production deployments.

Compiler & Language Design · Personal Project · 2020 – 2021

● Designed and implemented a simplified Python-like language from first principles in C, including a Shunting-Yard-based parser delivered as a tree-walking interpreter. Java Developer · Crafting Dead (Minecraft Modpack) · 2019 – 2020

● Member of a 4-person Agile team maintaining a modpack with over 2 million downloads.

● Owned cheat detection, VPN detection, bug fixes, and server administration across 5 Pterodactyl- hosted game servers.

● Rebuilt all server plugin code from scratch during a major Minecraft client version migration. Freelance Web Developer · Independent · 2017 – 2018

● Built and maintained client websites using PHP and SQL, delivering custom backend features for small business clients.

Systems Programmer · Personal Projects · 2018

● Learned Rust and built web servers, scrapers, bots, and network scanners using async I/O with Tokio. Web Designer & Developer · Independent / Community Platform · 2012 – 2016

● Created and sold custom CSS profile templates with a free tier, premium options, and self-serve tutorials; reverse-engineered the platform's frontend to expand what was stylistically achievable.

● Later expanded into Python scripting, producing bots and automation tools for the same platform.
