About this project
Finnal Grocery App is a custom product designed, developed, tested and deployed by our team, with the source code and accounts handed over to the client.
A promotional build for a grocery shopping application: the version made to be shown rather than shipped to a store. Promotional and pitch builds have a genuine engineering brief: they must demo flawlessly without a live backend, on someone else’s device, possibly without a network.
What a build like this covers
- Complete purchase journey from catalogue to order confirmation
- Seeded demonstration data so the flow works without a live backend
- Motion and transition polish through the flow being demonstrated
- Screen recording captured at device resolution for use in marketing
- Build configured so a demo cannot accidentally hit production services
What we watch for in e-commerce work
A demo build is separated from the production configuration entirely. Sharing a build that can write to real data is a mistake that only needs to happen once.
Stack
We build e-commerce products in Flutter and native Android and iOS on the client, with Node.js and NestJS services behind them, TypeORM over PostgreSQL or MySQL where the data is relational, MongoDB where it is not, and Firebase for authentication, push and analytics. Web panels are React. The choice follows the product. We do not start from a template and bend the requirements to fit it.
How we work
Every project starts with a written scope and screen list, moves through design and iterative development with regular demos, and ends with testing on real low-end devices before release. Clients own their code, repositories and store accounts. Where it adds genuine value, we integrate AI features (assistants, document extraction, recommendations) rather than bolting them on for show.
