GrubHub

The Challenge

When GrubHub acquired several regional delivery companies, each platform had legacy on-premise servers, older codebases and desktop applications, separate data models, no unified cloud deployment strategy, and different operational workflows across markets. The challenge wasn't just migrating systems — it was consolidating multiple companies' technologies into one cloud-based ecosystem while ensuring uptime, operational continuity, and long-term scalability.

Our Solution

Suntek Solutions delivered a comprehensive modernization and cloud-infrastructure strategy that supported both the acquired platforms and GrubHub's broader enterprise needs:

Complete Cloud Migration for Delivered Dish

Suntek moved Delivered Dish from basement servers to a fully cloud-hosted AWS environment. This included migrating VB6 and legacy desktop systems into modern web applications, building customer-facing and driver applications using hybrid mobile SDKs, rebuilding the website with reactive web technologies, and establishing a scalable, multi-city delivery infrastructure.

Enterprise Infrastructure Support for GrubHub

After the acquisition, GrubHub retained Suntek to support cloud infrastructure and multi-company unification initiatives. Suntek contributed AWS cloud management for dozens of high-availability systems, CI/CD orchestration with automated build and deployment pipelines, platform consolidation support for newly acquired delivery brands, and transition of disparate data sources into a unified operational model.

Multi-Platform Integration

GrubHub's acquisitions came with multiple codebases and system architectures. Suntek helped normalize data from multiple delivery companies, support new integrations for restaurants, menus, and logistics, maintain uptime across mission-critical operations, and provide rapid engineering support when legacy systems required extension or repair.
