AI Voice Agent Mobile App for University Admissions (Student Call Assistant) After resolving some earlier misunderstandings, the developer completed the project and delivered the application successfully. The app, APK, and admin panel were provided as agreed, and the remaining deployment steps were finalized. Communication improved during the later stages, and the final product works as expected. I appreciate the effort put into completing the project and bringing everything to a proper conclusion.

London, United Kingdom - 12:25 pm local time
I build AI agents, RAG knowledge assistants and business automation systems using Python, FastAPI, LangGraph, n8n and leading LLM APIs.

My Upwork history includes $100K+ earned across 98 contracts, 3,900+ hours and a 100% Job Success Score. I bring that production-software experience to practical AI systems that integrate with existing business tools and workflows.

I can help you build:

• AI agents with tools, memory and human approval workflows
• RAG assistants for documents and internal knowledge bases
• AI customer-support and lead-qualification systems
• Voice agents for calls, booking and customer service
• n8n and API-based business automations
• OpenAI and other LLM API integrations
• Python and FastAPI backends for AI products
• Vector search, document ingestion and structured retrieval
• Evaluation, monitoring and guardrails for AI outputs

My approach focuses on reliable production implementation—not just a demonstration. That includes structured outputs, error handling, logging, access controls, testing and clear technical documentation.

If you have an AI workflow or product in mind, send me your use case, current technology stack and desired outcome. I can review the requirements and recommend a practical implementation plan.
