Dope App

Mobile Commerce Platform

Serving 140+ dispensaries across 250+ retail locations, supporting hundreds of thousands of users.

  • Owned the end to end architecture and development of a white label mobile ecommerce platform built in React Native

  • Built and maintained mobile features supporting tens of millions in annual sales volume.

  • Delivered product enhancements across mobile ordering, checkout, search, and in store flows that correlated with an ~8% increase in average sales per dispensary.

  • Led mobile architecture refactors and CMS driven UI migrations, enabling vendor customization without app releases and reducing ongoing engineering overhead.

  • Developed a kiosk version of the app to provide a smooth in-store ordering experience, reducing wait times and increasing sales.

I led development and long term ownership of a multi-tenant mobile commerce platform used by cannabis dispensaries for online and in-store ordering. The product supports white-label branding, CMS-driven experiences, and high-volume transactional flows across mobile, web, and kiosk surfaces. I owned core architecture decisions and platform reliability while shipping features used by hundreds of thousands of end users in real retail environments.
