LLM Training for a Global Big Data Company

Client Profile

Industry: Data & Analytics
Headquarters: London, UK
Locations: Across Europe and the United States
Team Trained: 80+ Data Scientists, Analysts, and Engineers
Focus Area: Large Language Models (LLMs) – Practical Application & Integration

Challenge

This leading big data and analytics company had been exploring the integration of Large Language Models (LLMs) to enhance their internal data tools, automate client reporting, and innovate with generative AI.

Despite having strong in-house data science capabilities, the team needed:

Hands-on LLM training tailored to real-world use cases
Guidance on prompt engineering, fine-tuning, and deployment
Cross-functional upskilling for both technical and non-technical teams

They turned to JBI Training to deliver a customised program across their UK, EU, and US teams.

Solution

We designed and delivered a bespoke LLM training program, tailored to their industry, workflows, and tools. The course was delivered live (virtually and in-person), with hands-on labs, breakout sessions, and practical exercises.

Program highlights:

Understanding LLM architectures and capabilities (GPT, LLaMA, etc.)
Prompt engineering and chain-of-thought techniques
Retrieval-augmented generation (RAG) and enterprise use cases
Fine-tuning open-source models using company-specific data
Deployment strategies with APIs, LangChain, and vector stores
Ethical and secure AI practices for enterprise applications

Results

✅ 80+ professionals trained across multiple geographies
✅ Participants built working LLM prototypes during the course
✅ Improved confidence and clarity on AI adoption strategies
✅ Enabled smoother internal collaboration between data, product, and engineering teams

Client Feedback

🗣️ "One of the best training experiences we've had. The course was fast-paced, hands-on, and highly relevant to the problems we’re solving with generative AI."
— Head of Data Science, EU Region

Why It Worked

Tailored content to the client’s tech stack and industry context
World-class instructors with real-world LLM deployment experience
Flexible delivery across time zones and teams
Emphasis on practical use, not just theory

Next Steps

Following the success of the LLM training, the company has begun rolling out pilot AI tools built by the trained teams—and is now exploring further upskilling in AI governance, model evaluation, and custom AI product development.
