About this gig
Some tasks are too repetitive for a person but too unpredictable for a simple trigger. That's exactly what an AI agent is built for.
I'm Nathan, a UK-based developer building AI agents with n8n, Python, and models like ChatGPT, Claude, and Gemini. I connect an AI model's reasoning to the actions your business actually needs taken, not just a fixed if-this-then-that flow.
What I Offer:
- Custom AI Agents: Built with n8n, Python, LangChain, or CrewAI for multi-step, decision-based tasks.
- RAG Systems: Agents that reference your own documents and data for specific, accurate answers.
- Database Integration: Connect agents to your CRM, spreadsheets, or internal systems.
- Multi-Model Support: ChatGPT, Claude, Gemini, or others depending on what actually fits the task.
- Training and Documentation: A proper handoff so your team can run and maintain it, not just watch it work once.
Message me before ordering. A quick chat about your process and data means the right scope first time, and an honest answer on what an agent can realistically do for your specific task before you pay, not after.

UK-based developer building custom software, AI automation and data systems for businesses.
I work mainly with Python, JavaScript, n8n, Make, Zapier and APIs, building AI agents, RAG systems, web scrapers, browser automations, chatbots, CRM integrations, dashboards, GoHighLevel workflows, ManyChat automations and MT4/MT5 trading systems.
I also build full-stack web apps and internal tools. I can build from scratch or take over an existing system that needs fixing, extending or automating.
Message me with what you need and I’ll tell you how I’d approach it.

FAQ
What's the difference between an AI agent and a chatbot?
An agent takes actions and makes decisions across multiple steps. A chatbot mainly answers questions in conversation. Some builds are both, depending on what you need.
What AI models do you work with?
ChatGPT, Claude, Gemini, and others including Bedrock, Vertex AI, Grok, and Mistral. I'll recommend the right one for your task rather than defaulting to one every time.
Can the agent access my own data or documents?
Yes, that's what a RAG system does, the agent references your actual documents or database instead of just general knowledge, so answers are specific to your business.
Do I need a developer background to work with you?
No, you don't need to touch any code yourself. You describe what you need automated, I handle the build, and you get documentation for how to run it.
What if the agent gets something wrong?
AI agents are built for defined, bounded tasks, not unlimited judgement calls. Part of scoping the project is agreeing exactly what the agent should and shouldn't handle on its own.
Is the source code included?
Depends on the package. Message me if owning the full source and workflow matters to you and I'll scope it in from the start.
