Ideal Developer You should have real experience building AI agents, automation workflows, or AI-powered business tools. Experience with OpenAI, Claude, Python, FastAPI, React, Node.js, PostgreSQL, n8n, LangChain, or similar tools is preferred. The exact stack is flexible, but you must be able to build clean, maintainable systems that work beyond a basic demo. Key Requirements -Practical and clean architecture -API and database integration where needed -Approval steps for important actions -Logging, error handling, and basic security -Easy-to-maintain workflow structure -Clear documentation after completion Deliverables -Working AI agent or workflow system -Required API, CRM, or database integrations -Backend/frontend development where needed -Testing and bug fixing -Setup and maintenance documentation -Suggestions for future improvements To Apply Please share examples of AI agents, workflow systems, or AI-powered tools you have built before.
