About

I'm a senior full stack developer. I currently provide production support and internal tooling at Varsteel, and I build Web3 dApps freelance via Zipsite.net. Before that I spent 13 years designing and operating a large-scale multi-domain platform at Contrib.com, with contract work for Scanpointusa.com along the way. I like taking a real business workflow, whether it's a manufacturing floor or a token launch, and turning it into a system that actually holds up in production.
