I also take AI-built or half-finished apps to production: code audit, bug fixes, tests, deployment. Shipped with this workflow: Read My Cup, MySizer, Learnmix. Also OpenAI API features, RAG with embeddings, voice AI and MCP servers. HOW I WORK Code review first, clear milestones and acceptance criteria, small reviewed changes, everything on Upwork. Flexible hours, so I can overlap with your team's day. Building on Medusa.js, or have an AI-built app that needs to reach production? Tell me where it's stuck.
