About

Most software gets rewritten in three years. Mine doesn't.

I've watched frameworks rise and die. I've seen “revolutionary” platforms become legacy code in eighteen months. What survives isn't the cleverest solution — it's the simplest one that actually solves the problem.

I build infrastructure. The kind nobody notices because it just works — payment systems, blockchain protocols that secure drone fleets, platforms that other people build businesses on.

Work

What I've shipped — and why it mattered

01

CryptoIFF

2026

When authentication fails in defense, people don’t get error messages. Built a cryptographic IFF system for UAV fleets.

RustCryptographyDefense
02

WeAreFabbrik

2015

Got tired of building other people’s companies. So I built my own. IT consulting, SaaS products, custom software.

03

SpotFerret

2015

Turned a boring problem — parking — into an elegant system. Occupancy optimization that actually works.

TypeScriptReact
04

Smart Contract Attack

2023

You can’t secure what you don’t know how to break. Security research into smart contract vulnerabilities.

SolidityEthereumSecurity
05

Real Estate NFT

2022

What happens when property ownership lives on-chain. Tokenized real estate — the experiment that taught me the most.

Endurance

Nobody cares about your pace at mile 1. The race is decided at mile 20.

IRONMAN 70.3
2x
Marathon
CrossFit
Triathlon

Every Ironman teaches the same lesson: the body quits before the mind does. I've applied that to every company I've built, every system I've shipped, every problem I've refused to walk away from.
