About me

Why did I leave Crush?
Sadly Long Covid knocked me for six between 2022 & 2023. The stress of co-running an agency was making the condition worse so I chose to step away and recover my health.
I have now recover and looking for my next opportunity.
Employment
Founder
JWDM Limited | Sep 2024
Having left Crush I chose to set up a consultancy focusing on AI.
As a perpetual early adaptor I have been a heavy user of LLM.s since Chat GPT 3. I have tested a lot of models, including local installations from Hugging Face, and multimodal bots.
In my role as a consultant I work with four clients delivering traditional digital marketing support as well as AI consultation, projects and transformation support.
Notable work:
On site consumer facing chat bot - built, trained and wrote the prompt engineering for a system that can accurately quote for wine rack and wine cellar projects (preferred LLM Claude Sonnet).
Keynote speaker - Engaging with the business community and delivering education talks.
Vibe Coding - Built visualisation, calculators, and some many other things.
Automation - Using n8n to automated in house projects. Clients yet to buy (understand?)
Traditional SEO - Ranking clients on Google and now ranking for LLMs.

A fun, thought-provoking experiment, What Happens When You Give AI to a Dog? Maybe Chatgpt 4.5
