About

I'm a backend engineer with 7+ years in software development, now specialized in product AI — MCP servers, agent workflows, and measuring what they produce.

At GemCommerce I built the MCP layer that connects AI assistants to GemPages, so merchants can clone a page, generate a landing page or research a product just by chatting.

I'm looking for a senior/staff individual-contributor role.
