How Do You Make AI Work for Your Business?

Most teams start with ChatGPT and soon hit its limits. It doesn't know your products or policies; it can't see your customer records, and the same question can get a different answer each time.

That's the gap you close when you hire a ChatGPT developer who builds beyond the chat window. Your AI can:

Answer from your own documents, data, and policies

Connect to your CRM, database, website, and internal tools

Work within defined permissions and business rules

Trigger actions through your existing APIs

Hand over to a person when human judgement is needed

How Would You Like to Work With Our OpenAI Developers?

Some businesses need one experienced developer beside their engineers. Others want the whole build handled. Choose what you need.

Option Best for How it works As needs change
Dedicated Developer Ongoing AI product work A developer focused on your roadmap, working in sprints Add specialists as your roadmap grows
Project-Based Build A clearly defined feature or product Scope, deliverables, and cost agreed upfront Move into ongoing support after launch
Team Extension In-house teams missing AI skills Our developers join your team and follow your processes Adjust capacity as priorities shift

Our OpenAI Development Services

You don't need a technical specification. Start with the process, customer problem, or product feature you want to improve, and our OpenAI developer UK team will shape the solution around it.

Conversational AI and Chatbots

Conversational AI and Chatbots

Assistants that hold context, answer from approved information, and guide users through tasks, with human handover built in. For a product where conversation is central, you can hire a dedicated ChatGPT developer to own that layer and the integrations behind it.

OpenAI API Integration

OpenAI API Integration

OpenAI capabilities added to the CRMs, ecommerce platforms, dashboards, and bespoke software you already run, without replacing systems that work.

Knowledge Assistants (RAG)

Knowledge Assistants (RAG)

Assistants that retrieve answers from your documents, knowledge bases, and product information, instead of relying on a model's general knowledge.

AI Agents and Automation

AI Agents and Automation

Agents that work through multi-step tasks, use approved tools, and act within clear boundaries, from document processing to approval workflows.

Prompt Engineering and Fine-Tuning

Prompt Engineering and Fine-Tuning

Prompts are tested alongside application logic, retrieval, and validation. Fine-tuning is recommended only when testing shows it beats the simpler approach.

Generative AI Features

Generative AI Features

Text, image, speech, transcription, and summarisation features, with the model chosen for the use case rather than its release date.

How Do You Hire an OpenAI Developer From Coding Sprint?

You shouldn't need weeks of research to work out what kind of AI developer you need.

1. Tell Us What You're Building

A short call covering who will use the software, what AI should do, which systems it must work with, and any constraints.

2. We Identify the Skills You Need

The project's needs across OpenAI, integrations, data, and infrastructure decide the setup, whether that's one developer or a small team.

3. Meet Your Developer

You're introduced to the developer matched to your project, so you can discuss their experience before work begins.

4. Agree Scope and Kick Off

You agree on deliverables, the working model, and review points in writing, and you get direct access to the team from day one.

5. Build and Test in Sprints

Work arrives in reviewable increments, tested against realistic inputs, edge cases, permissions, and failure scenarios before users see it.

6. Launch, Monitor and Improve

After launch, we monitor and refine prompts, workflows, and model behaviour, and add new features as your needs grow.

What Do You Get When You Work With Coding Sprint?

Hiring someone who can call an OpenAI API isn't difficult. Building that API into dependable software is a different job. Coding Sprint, headquartered in Tunbridge Wells, Kent, treats every OpenAI project as a software project.

A developer matched to the work.

A knowledge assistant, a voice app, and a CRM agent need different experience, so the skills follow the project.

Direct access.

You speak with the people building your software, not through layers of account management.

Full software experience.

Your developer works across APIs, databases, backend, frontend, and cloud, so AI fits the wider application.

Production before the demo.

Permissions, failures, cost, and unexpected user behaviour are handled during development, not after launch.

Clear scope and confidentiality.

Deliverables and commercial terms are agreed before work begins.

OpenAI Developer Skills and Technology

The tools our OpenAI developer team uses depend on what you're building. Frameworks are only added when they solve a real requirement.

  • Responses API
  • Agents SDK
  • Realtime API
  • image generation
  • speech and transcription
