What I'm looking for

I’m open to relocation or remote work and available full-time immediately.

At SpaceApp, I conceived and built an open-source, self-hosted AI-agent workspace that brings 11 provider-native CLI runtimes into room-based workspaces. I added shared memory, governed MCP access, and persistent sessions that preserve work across web and API deployments.

At Olla.gr, the company I founded, I built and operated a production commerce platform with 40+ custom add-ons. Its supplier and marketplace integrations support 1.2M+ active products and up to 150K API calls per day.

My independent projects include Agent OS / Mission Control and API-driven workflows for CRM, email triage, and operations. I’ve also worked across ERP integrations, Linux infrastructure, and production reliability, including connecting CS-Cart to an Oracle-based ERP through custom NERO middleware.
