About
Senior IT Architect with 20+ years of enterprise experience, with a deep specialization in eCommerce platform engineering — from Oracle ATG and Oracle Commerce through to modern composable commerce on CommerceTools. This commerce foundation, built across retail, logistics, telecom, and grocery verticals, is backed by strong hands-on capability in Java, Spring Boot, and microservices architecture running on GCP and Kubernetes.
At Ulta Beauty, the role has grown from leading the ATG monolith to MACH migration and re-architecting to cloud-native microservices on GCP with CommerceTools to owning MarTech architecture, Personalization strategy across onsite and offsite channels, and Retail Media Network modernization strategy.
Applying LLM-assisted automation to accelerate implementations and reduce delivery overhead; prototyping agentic orchestration architectures to move from vendor-dependent to build-led delivery.
