Challenge

Walmart's KDP needed a technology partner to connect independent kirana stores to its replenishment centres. The same platform also had to serve restaurants, tuck shops, general stores and multi-store chains, and it was still running on legacy systems.

Approach

A multi-tenant, multi-vertical POS

One POS served several retail verticals and gave each store its own online storefront. Omnichannel POS-Pro covered billing, inventory, loyalty and CRM.

Multi-cloud for a major partner

I led the full integration and migration: AWS as the core, Azure for Walmart KDP.

Platform and security

I migrated legacy systems to microservices and aligned infrastructure and processes to security standards to achieve ISO 27001.

Forecasting

With the AI team, I built an internal demand-forecasting tool that was shared with Walmart.

Organisation

I also led cost reduction and team resizing.
