Senior Software Engineer specializing in AI automation, with Rails as the core stack. 7+ years of production software for clients in the US and Germany, 4+ of them on Shopify and BigCommerce apps.
I build AI agents in Rails that work with real business data, with only the permissions they need and a person approving the actions that matter. Public examples: an MCP server that gives Claude access to a store's products, orders and inventory (https://mjesar.github.io/projects/shop_mcp_server/), and an AI agent that scores how discoverable a Shopify product is to AI shopping assistants (https://mjesar.github.io/projects/product_geo_agent/). I also have three merged pull requests in the little_ghost Ruby agent framework.
Looking for remote full-time roles or contracts. I also take smaller projects, including AI discoverability (GEO and AEO) audits for online stores: https://mjesar.github.io/services/
Remote: Yes
Willing to relocate: Open to it
Technologies: Ruby on Rails, Ruby, PostgreSQL, Sidekiq, Redis, React, Hotwire, TypeScript, GraphQL, RSpec, Shopify (Functions, Checkout UI Extensions, Admin and Storefront APIs), BigCommerce, Amazon SP-API, LLMs, AI agents, MCP, RAG with pgvector, evals
