Mark P., CIO, FreshServ

Client Introduction

"FreshServ," a leading regional grocery chain in the American Midwest with over 150 stores and annual revenues exceeding $2 billion, was facing intense pressure from national competitors and pure-play delivery startups. Their existing "click-and-collect" website was outdated, lacked a mobile app, and couldn't handle the complexities of last-mile delivery. They needed a comprehensive digital transformation to defend their market share and create a new, significant revenue stream.

Problem and challenges in FinTech

Problem

FreshServ's lack of a modern, integrated online ordering and delivery system was leading to customer churn and a tangible loss of market share. They needed a solution that could not only provide a seamless customer experience but also integrate deeply with their existing inventory management, POS, and loyalty program systems.

Key Challenges

Migrating a massive, complex system with zero downtime

Integrating with a 20-year-old, custom-built ERP system for real-time inventory.

Ensuring compliance with strict financial regulations

Developing a logistics platform to manage a fleet of 300+ delivery vehicles efficiently.

Integrating with dozens of third-party financial institutions

Creating a personalized shopping experience for over 1 million loyalty program members.

Retraining their internal team to manage the new cloud-native environment

Ensuring the platform was scalable enough to handle massive peaks in demand during holidays and promotions.

Our Solution for FinTech

Our Solution

Developers.dev assembled a dedicated "Enterprise POD" of 25 experts, including enterprise architects, mobile developers, and AI specialists. We architected a cloud-native, microservices-based solution hosted on AWS.

🌉 Custom Middleware Layer

We built a robust API gateway and middleware to act as a bridge between the new platform and the client's legacy ERP, ensuring real-time inventory synchronization without disrupting existing store operations.

🤖 AI-Powered Personalization

We developed a recommendation engine that analyzed loyalty card data to provide personalized homepages, promotions, and "you might like" suggestions, increasing basket size.

🚚 Comprehensive Logistics Suite

We created a full suite of apps: a customer-facing iOS/Android app, a driver app with real-time route optimization, and a store-picker app to streamline the fulfillment process.

☁️ Scalable Cloud Infrastructure

Leveraging AWS services like EKS (Kubernetes), DynamoDB, and Lambda, we built an auto-scaling infrastructure that could handle 10x the normal traffic load with ease.
