James Grey Frontend & Internal Tools Engineer
I build frontend systems and internal tools where interface, data, workflow, and delivery all have to hold together.
For 19 years, I have built production websites and product UI for SaaS companies, agencies, and enterprise clients. At OEG, I found a messy QA/QC scheduling process, pitched a fix, and built the application field teams now use.
Professional and client work comes first below. Independent systems follow as supporting evidence of application development, integration, delivery, and operations.
