The challenge

What they were up against

Grocery is brutal: thousands of products, stock that changes by the minute, and a 6 p.m. rush that breaks normal systems.

istegelsin needed live stock counts, fast delivery at national scale, and easy search for shoppers on phones.

What we built

A national grocery platform built for real-time scale:

Live stock counts across stores. The app never sells what isn't there

Orders and deliveries planned against live courier capacity

Mobile-first shopping built for quick, frequent baskets

Infrastructure that absorbs the rush and bills for use, not idle servers

The outcome

What changed

Millions of weekly shoppers order through the platform. Stock counts and delivery promises hold through peak hours, with a lean team running it all.

Let's build something
exceptional.
