What I do
The same hands across very different stacks, from enterprise digital down to a soldering iron and a driveway.
Energy & home automation
Fox ESS solar + battery, tariff-arbitrage automations and AEMO price triggers, orchestrated through Home Assistant and ESPHome.
Component-level electronics
Vintage Yamaha, Marantz and Onkyo amps and receivers. Real paying-customer repairs, oscilloscope diagnosis, DC-bias work, recapping.
Self-hosted infra & AI agents
A home server running my own agent framework, Home Assistant, Jellyfin and a stack of self-hosted services, with MCP tool integrations across the lot.
Enterprise web & e-commerce
Years across DXP and composable commerce: Optimizely, Sitecore, AEM, Magento, Commercetools, .NET, Azure & AWS, headless on Next.js / Vercel.
Cars & shadetree wrenching
A driveway mechanic at heart: keeping JDM classics, 4WDs and vintage Mercedes on the road, and not above a few well-judged mods.
Services
