CRM/ERP Developer & API Integration Specialist

Professional Summary

I design and deliver bespoke CRM and ERP systems that replace spreadsheets, reduce duplicate data, and standardise how teams run sales, operations, and finance. Specialising in workflow-first delivery, I build secure, integration-ready solutions for manufacturing and wholesale businesses.

My approach prioritises process-led development over generic templates, ensuring each system aligns with real shop-floor and back-office flows. I focus on governance, security, clean API design, and comprehensive documentation to enable long-term ownership and extensibility.
