Grocery App

About this project

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 grocery shopping application. Grocery is the hardest retail category to build for: baskets are large, items are substitutable, stock changes hour by hour, and delivery slots are a scarce resource that has to be booked like an appointment.

What a build like this covers

• Catalogue with weight and unit-based pricing alongside per-item pricing
• Large-basket cart designed for 30+ line items rather than 3
• Substitution preferences for out-of-stock items, captured at order time
• Delivery slot booking with capacity per slot
• Order picking view for staff, ordered by aisle rather than by cart order
• Reorder from previous baskets, which is how most grocery orders actually get made

What we watch for in e-commerce work

Stock accuracy is the whole game. The app assumes stock will be wrong sometimes and makes substitution a designed flow, rather than pretending the catalogue is always right and leaving the picker to improvise.

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.
