Profile

Results-oriented and systems-focused.

I turn underperforming store systems into stable, accountable operations. I blend web development and data analytics with hands-on store operations and technical support. I’ve delivered workflow automation; integrated POS, loyalty and delivery channels; and built dashboards that improved margins, response times, and stock control.
