The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Inconsistent output structure
Model responses vary in format, breaking the code and systems that depend on them.
- 02
Generic tone and terminology
Base models do not reliably apply your domain vocabulary, style or classification scheme.
- 03
Provider lock-in
Capabilities are bound to one provider's API, making it difficult to switch as pricing or quality changes.
Overview
Foundation Model Integration & Fine-Tuning at VulcanTech
LLM integration is the embedding of large language models into existing applications and back-office systems so they can summarise, extract, classify and draft. VulcanTech integrates foundation models into your products and operations and, where prompting alone falls short, fine-tunes models on your examples to improve consistency, tone or cost efficiency. Every integration includes evaluation, fallbacks and monitoring, so the capability behaves predictably in production.
Key deliverables
- Integration architecture
- LLM service layer and API
- Fine-tuned model where justified
- Evaluation report
- Monitoring dashboard
What you get
What Foundation Model Integration & Fine-Tuning includes
Provider-agnostic integration layer
A unified service layer with retries, timeouts, fallbacks and rate-limit handling across model providers.
Structured output design
JSON schemas and validation so model output can be stored and processed reliably.
Domain fine-tuning
Supervised fine-tuning or adapters trained on curated examples where prompting reaches its limits.
Model routing
Simple requests routed to smaller, lower-cost models; complex requests to more capable ones.
Comparative evaluation
Side-by-side scoring of prompts, base models and fine-tuned models on your own test set.
Production telemetry
Latency, error rates, token usage and cost per capability tracked in production.

Our process
How we deliver
A delivery process you can see into — from first workshop to production support.
- 01
Discovery
A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.
- 02
Architecture & planning
We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.
- 03
Iterative delivery
Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.
- 04
Assurance & hardening
Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.
- 05
Launch & continuity
We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.
Engagement models
Work with us the way that suits you
Outcome-based delivery
A defined scope, timeline and commercial model agreed after discovery. We own delivery risk against the agreed outcomes.
Best for: Well-defined initiatives, MVPs and first releases
Dedicated product teams
A cross-functional pod — engineering, design, QA and delivery leadership — aligned to your roadmap and scaled as priorities change.
Best for: Long-term product development and evolving roadmaps
Team extension
Senior engineers embed in your organisation, work inside your processes and report to your leaders — on contracts that assign all IP to you.
Best for: Adding specialist capability without growing headcount

Why VulcanTech
A partner, not a vendor
Senior engineering, honest delivery, and work we can name.
Senior engineers own delivery
The engineers who scope your programme in discovery are the engineers who deliver it. There is no hand-off to a junior bench after contract signature.
Engagement models that fit
Outcome-based delivery, dedicated product teams, team extension or global capability centres, matched to how your organisation prefers to work.
A verifiable track record
Every customer story we publish describes real production work, naming the client wherever confidentiality allows, including public-sector platforms secured through competitive tenders.
80+ projects in 16 countries
Delivered since 2021 across the public sector, real estate, healthcare, manufacturing and consumer technology, for regulated and high-growth organisations alike.
