AI feature integration for existing SaaS products
Your product already works. You need AI inside it — summarisation, semantic search, an assistant, automated generation — without rebuilding the thing that already works. I integrate LLMs into live SaaS products, handling the parts that actually make AI features hard: cost control, latency, streaming, evaluation, and graceful failure.

Where teams get stuck
The demo worked, production did not
A prompt in a notebook is not a feature. Rate limits, token costs, streaming UX, retries, and hallucination handling are where AI projects stall — and they only appear once real users arrive.
AI costs are unpredictable
Without caching, model routing, and token budgeting, one power user can cost more than they pay you. I build cost controls in from the start rather than after the first alarming bill.
Your team has never shipped AI before
Choosing between fine-tuning, RAG, and prompt engineering is an architecture decision that is expensive to reverse. Most teams over-engineer it — usually RAG plus good prompts is enough.
What you get
- LLM integration with OpenAI, Anthropic, or open models — with fallback routing
- Retrieval-augmented generation over your own data, with a real vector store
- Semantic and hybrid search that beats keyword matching on your content
- Streaming responses with proper loading, cancellation, and error states
- Token budgeting, caching, and per-user rate limits so costs stay bounded
- Prompt versioning and an evaluation harness so quality does not silently regress
- Monitoring on latency, cost per request, and failure rate
How it works
- 01
Feasibility review
I look at your product and data, and tell you honestly which AI feature is worth building first — and which ones will not survive contact with real users.
- 02
Thin vertical slice
One feature, end to end, in your real codebase. Working in production within days, so you learn from actual usage instead of a mockup.
- 03
Hardening
Cost controls, caching, evaluation, and failure handling. This is the part that separates a feature that ships from one that quietly gets rolled back.
- 04
Expansion
With one feature proven and instrumented, additional AI surfaces are fast to add on the same foundation.
