AI Integration

AI integration that makes your product smarter.

AI is most valuable when it is quietly built into a workflow people already use: drafting a reply, summarising a document, pulling data out of a form, or answering a customer at any hour. I add these features to existing web applications without a rebuild, and with the same engineering standards as the rest of your product.

I work across the major model providers, including OpenAI, Anthropic Claude, Google Gemini and xAI Grok, and choose the right model for each task on quality, speed and cost. The work goes well beyond calling an API: prompt design, grounding answers in your own data, streaming responses, handling failures and keeping costs predictable as usage grows.

How We Work Together

A clear process. No surprises.

Every project follows the same simple steps, so you always know what is happening, what it costs and what comes next.

  1. 01

    Discovery call

    We talk through your goals, users and constraints. I ask the questions that shape scope, and you leave with a clear recommendation, even if we don't work together.

  2. 02

    Plan & estimate

    You receive a written scope with milestones, technology choices, timeline and a fixed price or clear hourly budget. No surprises later.

  3. 03

    Build in the open

    Work ships in short milestones to a live staging site, with regular updates, so you see real progress and can steer early.

  4. 04

    Launch & support

    I handle deployment, monitoring and handover documentation, then stay available for improvements, fixes and the next phase.

FAQ

AI Integration: frequently asked questions.

Can you add AI to my existing app without rebuilding it?

Yes. AI features are usually added as new API endpoints and interface components alongside your existing code, whether it is built in React, Next.js, Node.js, Laravel or Python.

Which AI model should I use: OpenAI, Claude, Gemini or Grok?

It depends on the task. Some models are stronger at writing, others at reasoning, long documents or speed and price. I test the options on your real data and often use different models for different features, behind one interface so you can switch later.

Can the AI answer questions from my own documents?

Yes. Your documents are split into passages and stored in a vector database, and the most relevant passages are given to the model with each question. Answers are based on your content and can show their sources.

How do you keep AI costs under control?

Through caching repeated requests, choosing the right model for each task, limiting how much text is sent, per-user usage limits and monitoring, so costs stay predictable as usage grows.
