Apps

Mobile apps and startup products built to solve real problems, not just look good in a portfolio.

Each project is presented as a product story: what needed to be solved, how the system was designed, what technologies supported it, and why the outcome matters for real users or operators.

Mobile Apps
Inventory-aware mobile commerce for fresh product ordering and fulfillment.

Thriving Greens

A commerce app designed around real inventory constraints so customers can order confidently while operators avoid overselling and fulfillment gaps.

Problem

Customers could attempt orders that operations could not fulfill accurately because the storefront did not reflect live inventory reality.

Solution

Built an inventory-aware ordering flow with weight-based availability logic, clearer UX feedback, and a more trustworthy purchase path.
