What You'll Receive
Full Description
If your business is sitting on untapped data, repeating the same manual processes, or simply needs a smarter, AI-powered capability — this service delivers a production-ready solution built precisely to your requirements.
Whether you need a conversational AI chatbot that actually knows your business, a predictive machine learning model, a computer vision pipeline, or an automated n8n workflow that eliminates repetitive admin, this is the service for you.
**What you receive:**
At the entry level, you receive a focused, working AI solution — a simple chatbot or agent, a machine learning model, or a lightweight automation — complete with clean source code delivered within two days. This is ideal for proof-of-concept builds, single-feature prototypes, or tightly scoped tasks.
The standard tier adds dataset preparation so your data is properly structured before modelling begins, detailed code comments so your team can maintain and extend the work, and unlimited revisions — giving you a polished, well-documented solution ready for hand-off.
The full-service tier goes further still: your project includes everything in the standard tier, plus a fine-tuned AI model trained specifically on your proprietary data, and full model deployment via Streamlit or FastAPI so the solution is live and accessible to your users from day one.
**Capabilities covered:**
• Machine learning and deep learning — predictive analytics, neural networks, sentiment analysis, and object detection using PyTorch and Python
• AI chatbots and agents — custom RAG, Agentic RAG, and Graph RAG systems built with LangGraph, LlamaIndex, and OpenAI for accurate, hallucination-resistant knowledge retrieval
• LLM fine-tuning — specialising models from HuggingFace and OpenAI on your custom datasets for meaningfully improved accuracy
• AI workflow automation — multi-agent systems built with LangGraph, CrewAI, and LangChain for complex, stateful business processes
• n8n workflows — custom automations for repetitive tasks such as data entry, CRM updates, and report generation, with documented results in operational cost reduction
• Computer vision — object detection and image classification pipelines using YOLO and PyTorch
• Scalable deployment — Streamlit dashboards and FastAPI backends for production-ready delivery
**Who this is for:**
This service suits founders, product teams, data teams, and operations leads who want a working AI solution — not a presentation deck. It is equally suited to businesses exploring AI for the first time and to technical teams who need a specialist to accelerate a specific capability.
**Why this seller:**
With over three years of hands-on experience in machine learning, deep learning, and modern AI systems, this is a Google-vetted freelancer based in London, England. Every solution is built to be deployment-ready, well-documented, and genuinely client-focused — delivered in days, not weeks.

Frequently Asked Questions
Custom RAG chatbots, Agentic RAG systems, and Graph RAG architectures using LangGraph, LlamaIndex, and OpenAI models such as GPT-4 and Llama 3. These are designed for accurate, contextual knowledge retrieval with minimal hallucination.
Predictive analytics, neural networks, sentiment analysis, computer vision pipelines, and NLP classifiers — all built using PyTorch and Python, tailored to your dataset and objectives.
Fine-tuning adapts a pre-trained language model (such as Llama 3, GPT-4, or DeepSeek) to your specific data so it responds with far greater accuracy on your domain. It is included in the Premium tier and is particularly valuable when you have proprietary documents, product data, or specialised terminology.
n8n automations connect your existing tools and handle repetitive tasks — data entry, CRM updates, report generation — without manual intervention. This frees your team to focus on higher-value work.
As a minimum, a clear description of what you want the solution to do, any relevant data or documents you have, and details of the tools or systems it needs to connect with. The more context you provide, the faster and more accurately the build can begin.
The Basic tier includes two revisions. The Standard and Premium tiers include unlimited revisions, meaning adjustments are made until the deliverable meets your requirements. All revision requests should be submitted via the order chat.
The Premium tier includes full deployment via Streamlit or FastAPI, so your solution is live and usable on delivery. Basic and Standard tiers deliver working source code that can be run in your environment; deployment can be added as needed.
For anything beyond a straightforward scope, yes — it helps ensure the right tier is selected and that the delivery timeline is achievable for your specific project. Use the platform messaging to reach out before ordering.
