About Me

Engineer. Consultant.
Automation Specialist.

I specialise in designing n8n-based automation that connects systems, processes data intelligently, and eliminates repetitive manual work. With a strong focus on API integration, AI/LLM pipelines, and production-ready systems, I build things that scale.

I enjoy transforming complex operational processes into reliable automated workflows. Comfortable working directly with stakeholders to understand requirements, and iterating quickly based on real-world feedback. My approach is pragmatic: I focus on delivering measurable outcomes, not just technology.

Currently available for contract engagements across the UK and EU, working remotely or on-site as needed.
