Senior Developer for Agentic AI Copilot

Hi, I am looking for a senior developer to build an agentic AI copilot that can understand typed or spoken natural-language instructions and perform multi-step tasks inside a complex web application. The project requires strong experience with AI agents/LLMs, browser automation, Playwright or similar tools, Chrome extensions, dynamic web forms, and human-in-the-loop workflows. Before I share the full project details, could you please send me examples of anything you have built where an AI agent could navigate a website or software application, understand a task, perform multiple actions, fill forms, and return the completed work for user review? Please also briefly describe the technical architecture you would recommend for this type of system.
