Full Description
If your business needs to automate conversations, retrieve real-time information intelligently, or harness the power of machine learning — this service delivers a working, production-ready AI solution tailored to your exact requirements.
Whether you have a clear brief or are still exploring what is possible, you will work with a London-based AI and Machine Learning specialist who holds recognised certifications in AI and Data Science. The focus is always on fast, thoughtful delivery — no corners cut, no bloated solutions.
**What you can get built:**
AI Chatbots and Agents — intelligent conversational systems that retrieve real-time data, understand context, and respond meaningfully to your users. Built using modern agentic frameworks including LangGraph, CrewAI, and LangChain, or orchestrated with n8n for seamless workflow automation.
Machine Learning and NLP Solutions — predictive analytics models, sentiment analysis pipelines, text classification systems, neural networks, and more. Grounded in your data, built for real-world performance.
LLM Fine-Tuning — take a powerful pre-trained model such as GPT or a Hugging Face LLaMA variant and make it significantly more effective on your specific domain, tone, and dataset.
RAG Systems — Retrieval-Augmented Generation pipelines that allow your AI to query your own documents, databases, or knowledge bases before generating a response.
Deployment-Ready APIs and Apps — delivered via FastAPI or Streamlit so your solution is ready to integrate or demo immediately, built to scale.
**What every delivery includes:**
All packages include full source code and detailed, readable code comments so your team can understand, maintain, and extend what has been built.

Frequently Asked Questions
Share as much detail as you can about your project — what the chatbot or model should do, your intended users, any data you have, and your preferred technology stack if you have one. If anything is unclear, questions will be raised via the order chat before development begins.
Yes. You do not need a technical background. Share your goal or problem in plain language and the right solution will be recommended. The delivered code will be fully commented so a developer on your team can also pick it up easily.
The core toolkit includes Python, PyTorch, Hugging Face, OpenAI, n8n, LangGraph, CrewAI, LangChain, FastAPI, and Streamlit. The most appropriate combination is chosen based on your specific requirements.
Fine-tuning involves taking an existing large language model and training it further on your own data so it performs better in your specific domain, tone, or use case. It is included in the Premium package and is worth considering if you need the model to reflect your business's specific knowledge or style.
RAG stands for Retrieval-Augmented Generation. It allows an AI model to search your own documents, databases, or knowledge base before generating a response, making answers far more accurate and grounded. This capability is available within the Standard and Premium packages depending on the complexity required.
Revisions cover adjustments to the delivered solution based on your original brief. Each revision round should consolidate your feedback clearly. The Premium package includes unlimited revisions; Starter includes 2 and Standard includes 3.
Yes. All packages include the full source code with detailed comments, so you own and understand everything that has been built for you.
Absolutely. Send a message via the order chat describing what you have in mind and a recommendation will be made before you place your order.
