01 / How I can help

A clear starting point for your website.

Whether you need a new website or your current one no longer explains your business well, we can start with the pages and enquiry journey that matter most. I review each project before agreeing the scope, timing and cost.

A focused website or landing page

For a service business that needs to explain its offer clearly and give prospective customers an obvious next step. I can help organise your content, design the pages and build a responsive site around that journey.

Available now
  • Page structure and content priorities
  • Responsive design and front-end development
  • A clear contact or enquiry route
  • Keyboard, readability and mobile checks
  • Page titles, descriptions and technical search foundations
  • Agreed handover notes

Improvements to an existing website

For a site that broadly does its job but has a specific problem: confusing navigation, difficult mobile layouts or a page that makes the service hard to understand. We identify the issue and agree a focused set of changes.

Available now, subject to a technical review
  • Review of the relevant pages and user journey
  • Content structure and interface improvements
  • Responsive layout and accessibility fixes
  • Verification of the agreed changes

An AI document assistant for your business

Answers questions about your own documents and shows the sources behind each answer, so the people relying on it can check the work. I have built and deployed this twice — Cited, measured against a committed evaluation set, and E.V on this site — so this is a capability I offer rather than an idea I am exploring.

Available now
  • Retrieval grounded in your approved documents
  • Every quoted passage verified against its source
  • Questions the documents cannot answer are refused, not guessed
  • Cost controls, rate limiting and an evaluation set that measures answers
  • A management view over questions, answers and knowledge gaps
  • Agreed scope, stated limitations and handover notes

Scope note: Each assistant is built around a defined set of documents and a defined job, and I say plainly what it does not cover. Extending one beyond that scope needs its own privacy review, running costs and support arrangements, agreed before the work starts.

Related work: I also have experience delivering AI, Python and data training, and working on digital content and e-commerce operations. Ask about a specific requirement and I'll confirm whether it fits.

Inside the project

Cited — Document Assistant

Live

A document assistant that retrieves relevant passages, generates an answer, and checks quoted text against the passages supplied to the model. It is designed to decline questions its documents do not cover, and its small evaluation set tests both answerable questions and questions the documents cannot answer.

03 / How I work

Know what we are building, and why.

I want to build products that help people understand information, complete a task or run part of their work more easily. In practice that means agreeing a manageable scope, reviewing the work as it develops and checking the important details before handover.

  1. Understand the job

    We clarify who the site is for, what they need to know and what they should be able to do. I will ask about your existing content, constraints and priorities.

  2. Agree the scope

    I set out the pages or features, what each of us needs to provide, the review points and how we will judge the work. Timing and price follow from that scope.

  3. Build and review

    I turn the agreed direction into a working version, share progress and use your feedback to resolve the details.

  4. Check and hand over

    I test the agreed journeys, review mobile and keyboard use, and explain how to maintain the result. Any remaining limitations are made clear.

Working principle: You work directly with me. I remain responsible for the decisions and the delivered work.

04 / Let's talk

Tell me what your website needs to do.

Share a little about your business, who the site is for and what is getting in the way. If you have an existing website, include the link. A rough timeline and budget range are helpful if you know them.

You do not need a technical brief. I'll review the details and let you know whether I can help and what the next step could be.
