I’m rolling out a programme that blends large-language-model reasoning with agent-based orchestration directly inside Automation Anywhere. The mandate is clear: redesign several labour-intensive business processes and have them run as fully self-governing, monitorable workflows. Your background should show real wins where AI agents drove end-to-end workflow automation, not just isolated chat or recommendation pilots. You’ll map the architecture, prove the concept, then shepherd it into production, coordinating a small in-house team along the way. Expect to craft prompts, manage model hosting or fine-tuning (OpenAI, Anthropic, Hugging Face, etc.), and expose everything through Automation Anywhere packages or REST calls. Familiarity with frameworks like LangChain or similar agen...

I want a clear, professionally-made screen recording that walks through the complete setup and configuration of an AI workflow built around OpenAI GPT. The video must cover every step—from account creation (if relevant) through environment preparation, API key management, sample code execution, and a brief demonstration that shows the model responding to at least one prompt so viewers can verify everything is working. Because I will be using this recording commercially, please capture clean audio narration, concise on-screen callouts, and ensure no proprietary or personal data appears anywhere. The final deliverable should be: • Full-HD or 4K video file (MP4 or MOV) • Clear voice-over explaining each action as you perform it • Source commands or snippets shown in...

I’m ready to move from a collection of manual workflows to a single AI-powered virtual assistant that lives wherever my users already are.

Project title: Build an AI App-Builder Platform (agentic, natural-language to full-stack apps, websites & software) Overview I'm building a web-based AI platform that turns a plain-language description into a working, deployable full-stack application — in the same category as Emergent, Lovable, Replit, v0, Bolt, and Caffeine AI.

I'm looking for a developer or small team to build this end to end. Experience building agentic / LLM-powered products is essential — this is not a standard CRUD web app. Core scope Chat workspace where users describe and refine apps in natural language ...

I’m planning an AI-driven video created solely for entertainment and need a skilled collaborator who can take the idea from concept to polished, share-ready footage.
