I designed and built JobQuoteFlow, a full-stack SaaS quoting platform for trades and service businesses. It transforms rough job details into polished, customer-ready quotes using configurable labour rates, materials, markup, margins, call-out fees and GST. I built the complete product experience, including quote creation and management, pricing rules, customer proposals, Good/Better/Best options, online accept/decline functionality, authentication, business settings and a responsive interface. The project was taken from initial concept through product design, development and production deployment.
