Home Depot

Challenge

Home Depot was in the early stages of a multi-year technology transformation. The retail platform needed to support an increasingly digital customer experience while maintaining reliability for over 2,000 physical stores. Engineering teams were growing rapidly, but the platform architecture and engineering practices hadn’t evolved to match the scale of ambition.

The core tension: move fast enough to compete digitally while maintaining the operational discipline that a retailer of this scale demands.

Approach

This engagement focused on building the foundations — both technical and cultural — that would support Home Depot’s engineering organization through years of growth and transformation.

Platform architecture: Worked with platform teams to design service boundaries, define API contracts, and establish patterns for shared infrastructure. The goal was an architecture that allowed teams to move independently without creating fragmentation.

Engineering culture: Introduced practices around code review, testing standards, and production readiness. These weren’t top-down mandates — they were developed collaboratively with engineering leads and adopted through demonstrated value.

Operational maturity: Established incident management processes, on-call rotations, and post-incident review practices. Built observability into the platform from the ground up rather than bolting it on after incidents.

Outcomes

• Platform architecture established patterns that supported the organization through subsequent cloud migration phases
• Engineering culture practices — code review, testing, production readiness — became embedded in how teams operated
• Platform incident frequency measurably reduced through improved operational practices and observability
• Created a foundation that made the later large-scale cloud migration (2019) significantly less risky
