About this gig

Need a practical AI agent or RAG assistant built around your workflow? I build custom solutions with GPT, LangChain, Python, FastAPI, Docker, and private-deployment options.


What I can build:

- AI agents for customer support, operations, lead qualification, and document Q&A

- RAG chatbots grounded in your PDFs, website, or database

- OpenAI or LLM API integrations with tools and function calling

- Lightweight workflows using n8n, Coze, or Dify


You will receive a working implementation matched to the package, clean Python source code, setup notes, and a tested handoff.


For multiple data sources, production deployment, a custom UI, advanced integrations, or a multi-agent system, please message me before ordering. I will confirm a realistic scope and timeline first.

I build music, voice, and agent AI products from prototype to tested delivery. I hold an MSc in Sound and Music Computing from QMUL and have 4 years of AI R&D experience. My work includes EmoHeal—emotion analysis plus therapeutic music retrieval/generation—and VoxSketch, a voice-to-editable-song workflow using Audiotool NEXUS. I deliver generative music workflows, STT/TTS, audio analysis, voice agents, RAG, FastAPI, Docker, source code, tests, and documentation. Expect clear scope, honest technical boundaries, milestone delivery, and a system you can keep building after handoff.
