Nine years of advisory and production AI.
I started in AI at EY in 2017, then spent four years at a Brazilian AI startup, later acquired by one of the country's largest banks, leading delivery for health insurers, banks and retailers. Most recently I built deep learning forecasting models for TotalEnergies while completing an MSc in Computer Science.
Today I run Retrieverworks, the AI and automation studio I founded in York: AI agents, workflow automation and bespoke builds, taken from prototype to production.
Client work runs through Retrieverworks. Freelance and contract work through Upwork.
Big-firm AI, sized for a small business.
Retrieverworks is the AI and automation studio I founded, based in York and working with businesses across the UK. I build AI agents, workflow automation, systems integration, data migration and bespoke web applications, scoped honestly and shipped to production.
- Repetitive work, automated.
- Enquiries answered in seconds.
- Answers buried in your documents.
- Know your customers.
A small, deliberate track record.

Financial services clients (banks, insurance, pension funds): data analytics, automation, early machine learning. Self-taught Python in 2018 when no one else on the team was using it, then built a web scraping and NLP pipeline that classified 100,000+ court documents and led a workstream on LGPD data privacy compliance.
Things I build for myself, outside client work. They keep my deployment, CI and observability habits sharp.
