Part-time senior Rails and AI engineer, 20 hours a weekMohammad Ali Jesar
A senior software engineer specializing in AI automation, on your team for 20 hours a week. I work results-first: we agree on the outcome, define the scope, and work toward it in small, reviewable steps.
What you get
About 80 hours a month of senior work, from $3,000 a month:
New features, fixes and upgrades in your Rails app.
AI features that work with your real data: LLM integrations, MCP servers, RAG and AI agents.
Shopify and BigCommerce apps and integrations.
Need more? Full-time (40 hours a week) is from $6,000 a month. Monthly contracts get a lower rate than one-off projects because the hours are guaranteed.
How I work
Based in Lahore, Pakistan (UTC+5), with flexible hours for U.S. and European time zones. I usually reply within a few hours. I use AI tools to work faster, and I review and test every change myself.
Evidence
7+ years of production Rails for clients in the US and Germany, 4+ of them on Shopify and e-commerce. Open-source AI work: shop_mcp_server, ai_shop_assistant and product_geo_agent.
