Delivery story

Palmstreet: Buy & Sell LIVE: a focused product delivered from discovery to release

01

Challenge

The client needed a focused product for live-commerce buyers and sellers. The first release needed seller listings, live-session inventory, and checkout handoff, while managing inventory and transaction edge cases.

02

How we built it

We mapped the core journey and data model first, then delivered seller listings as a working vertical slice. The next iteration added live-session inventory and checkout handoff, with authentication, validation, loading and failure states designed into each flow. A mobile-first TypeScript build using React Native, Expo, TypeScript, Node.js kept the interface and service contracts consistent; the final weeks focused on QA, accessibility, and release preparation.

03

Delivery

The delivered 16-week MVP let live-commerce buyers and sellers complete the core journey without relying on disconnected tools. It provided a small, maintainable foundation for testing demand and prioritising the next release.

Coralsoft turned the product brief into a maintainable 16-week MVP.

Challenges

Each constraint, and what we did about it.
