For teams that already have software and want AI added into it — without rebuilding the product.
AI Integration for Existing Products
You don't need to start over to add AI — your existing system is the starting point.
I integrate OpenAI, Claude, Gemini, retrieval, and AI assistants into products you already ship — using the languages, frameworks, and infrastructure you already have.
Most AI integration work is straightforward once you know what data the model needs to see.

Plug AI into the product you already ship.
Most AI work is integration work. The model, retrieval, and tool layer plug into your existing service mesh — not the other way around.
Compatible
Works with the stack you already have.
Bounded
Scope changes, not rewrites.
Reversible
Architecture that can evolve.
Bring what you already ship
We'll figure out where AI fits.
Who this is for
AI integration fits teams that already have a working product and want AI features added on top of it.
SaaS companies extending their product with AI
Internal-tools teams adding AI to existing workflows
WordPress / WooCommerce stores adding AI assistance
API products adding AI endpoints or agents
Teams that want AI added without a full rewrite
When your product needs AI
If any of this matches what your team is planning, AI integration is usually the simplest path.
Your users keep asking the same questions
An assistant grounded in your product or company data can answer them reliably.
Your team repeats the same structured work
LLMs can draft, summarise, qualify, and route — without changing your existing systems.
Your product is missing smart features competitors have
AI assistants, recommendations, summaries, and semantic search are usually one integration away.
Your data is valuable but inaccessible
Retrieval over your own documents turns documents, tickets, and notes into answers.
What I integrate
AI capabilities that plug into an existing application.
- OpenAI / Claude / Gemini APIs

AI integration architecture
How AI features plug into an existing product without forcing a rebuild.
Service-layer boundary
AI features live behind a service that the existing app already calls — so changes stay contained.
Data access through your own APIs
Retrieval uses your existing data sources — no parallel databases or duplicate pipelines.
Authentication inherited
The AI features inherit the same auth model as the rest of the product — no new edge cases.
Structured outputs where it matters
Tool calls and JSON schemas replace free-form text in places the rest of the system has to parse.
Application context
User, tenant, and product context are passed into prompts so answers stay relevant.
Observability from day one
Latency, cost, and quality are logged in the same observability stack as the rest of the app.
How integration projects run
A small engagement model — short enough to add AI without slowing the rest of the roadmap.
Where AI fits
Identify the highest-value place to add AI in the existing product and the smallest change to ship it.
Architecture sketch
Decide the model, retrieval, service boundary, and how the existing app talks to the new layer.
Integration
Add the service layer, expose its APIs, and connect it to the existing UI or APIs.
Evaluation and rollout
Evaluate outputs, add guardrails, and roll out behind a feature flag or to a small cohort first.
Hardening
Improve prompts, retrieval, error handling, and observability based on real usage.
Relevant work
AI work that lives inside a real product.

Frequent AI integration shapes I've shipped or scoped.
AI assistant inside an existing SaaS
A bounded assistant that uses your existing data to answer product questions.
AI-assisted drafting and summarisation
Drafts, summaries, or rewrites inside the product's existing workflow.
AI-enriched records
Existing records — leads, tickets, opportunities — enriched or scored by an LLM.
AI semantic search
Replace keyword search with retrieval over your documents, tickets, or content.
RAG over company documents
Answers grounded in your documentation, knowledge base, or content library.
Frequently asked questions
Answers to common questions about integrating AI into an existing product.
No. Most AI work is integration work — wiring models, retrieval, and tool use into the systems you already ship. The aim is scope, not rewrites.
Primarily OpenAI, Claude, and Gemini. The right model depends on capability, latency, cost, and data-handling requirements.
Yes. I work alongside your existing engineers, in the languages and frameworks the codebase already uses.
Integration focuses on adding AI to software that already exists; development focuses on building software around AI. See the AI Development page for the other side.
Yes — see the RAG Development page for the architecture and the integrations I typically build.
Depends on the surface area. Many focused integrations land inside a few weeks; broader rollouts are scoped project-by-project.
Tell me what you're building.
Most AI integrations are simpler than they look. A short brief is usually enough to know whether AI fits — and what the smallest integration would look like.
