AI & Data Consultant

About

Hi, I’m Douglas Woollam

My obsession with AI began during my MSc in Bioinformatics at UCC, where I used AI and data science to automate the discovery of data in the human genome.

I’ve since worked as an AI and Data Specialist contractor on Apple’s EMEIA Business Sales team.

My favourite work at Apple unlocked over $3 million in revenue, automated four hours of manual work every day and reduced false negatives by 95%. I achieved this by building an AI workflow that automatically processed more than €50 million in customer sales data and applied the company’s business rules consistently.

After thousands of hours testing AI tools, I created a simple framework that I now use in my own work and with clients:

AOA. It stands for Audit, Optimise, Automate. The methodology is deliberately simple: find the time or money leak, fix the process before layering on AI, then automate the new optimised process.

I also write the blog on this site and keep active on LinkedIn with current AI content. And I run Cork AI for Business, a monthly meetup for local businesses where I share practical AI and data advice.

I live in Mallow, Cork.
