Full-Stack Web Developer

Hi, I'm Sig. I write code, break things on purpose (in staging), and fix ecommerce systems for a living.

I've been building for the web since 1996 and living inside ecommerce since 2010: Shopify, Amazon, eBay, the whole messy family of platforms. Somewhere along the way I got good at making the boring, business-critical stuff actually work.

What AI-assisted development looks like inside a real business

I use Claude Code, Codex, Cursor, and Gemini daily, as part of a workflow, not as a replacement for one. System design and correctness review stay mine; the tools speed up implementation.

Have an ecommerce or product-data problem worth solving?

I take on a limited number of contract and fractional engagements each quarter.
