At Dev Centre House Ireland, we understand that unlocking the full potential of Large Language Models (LLMs) requires more than just powerful algorithms—it requires precise, creative, and structured communication between humans and machines. With deep expertise in applied AI and product engineering, we offer Prompt Engineering Services that integrate cutting-edge language model capabilities into real-world software, enhancing performance, automating workflows, and accelerating innovation.

Transform Your AI Capabilities Today

Partner with Dev Centre House Ireland to harness the intelligence of advanced LLMs through meticulously engineered prompts. Our solutions are built to drive smarter systems, scalable performance, and exceptional results across industries.

Scope

Comprehensive Prompt Engineering Services

Prompt Design & Optimization

We craft effective, structured prompts tailored to use cases like chatbots, classification systems, summarisation tools, and autonomous agents.

Prompt Frameworks & Libraries

Our team creates reusable, modular prompt libraries to support consistency and scalability across different models and teams.

Prompt Evaluation & A/B Testing

We perform controlled testing and benchmarking of prompt variants to optimize for output accuracy, consistency, latency, and cost.

Model-Specific Prompting

Our specialists engineer prompts for top-performing LLMs including OpenAI’s GPT-4, Anthropic’s Claude, Google Gemini, Mistral, and Meta LLaMA.

RAG & Hybrid Systems Co-Design

We align prompt engineering with retrieval systems, context augmentation, and multi-model routing for robust, grounded outputs.

Prompt-to-Finetune Strategy Consulting

We advise on when to move from prompt engineering to dataset design, fine-tuning, or instruct-tuning workflows for model specialisation.

Problem

The Pain Point

AI is everywhere. But let’s be honest – most businesses are disappointed.

  • Prompts don’t deliver consistent results.
  • Outputs are generic or wrong.
  • Teams waste hours tweaking instead of working.

Mostly, It’s not the AI’s fault. It’s the prompts.

Solution

Our Solution – Business-Grade Prompt Engineering

At Dev Centre House, we specialise in prompt engineering:

  • Custom prompts tailored to your business use case.
  • AI workflows that are repeatable, reliable, and measurable.
  • Seamless integration into existing processes.

We’re not outsourcing — we’re an extension of your team: agile, responsive, and accountable.

Process

Our Prompt Engineering Process

With over a decade of software and AI development experience, our approach ensures every engagement—from experimentation to deployment—is efficient, robust, and tailored to your use case.

  • 0 1

    Discovery & Assessment

    We start by understanding your business needs, product goals, and existing systems. We assess where LLMs can add value and map out prompt-driven opportunities.

  • 0 2

    Proposal & Planning

    Our team prepares a clear project scope, resource plan, model selection, and prompt development timeline tailored to your objectives.

  • 0 3

    Development & Testing

    We craft, evaluate, and integrate prompts. Testing includes synthetic evaluation, output scoring, and human feedback loops to ensure production readiness.

  • 0 4

    Integration & Scaling

    Once validated, we integrate prompts into your apps, APIs, or agent systems. We also implement logging, monitoring, and iteration pipelines to support continuous improvement.

Cost

How much do Prompt Engineering Services cost?
