Professional Experience

Kroger

Advanced Software Engineering Manager

2022 — Present Day | Cincinnati, OH

Leading four competent, delivery-focused software engineering teams to develop an omnichannel payment platform for Kroger that supports in-store and e-comm properties. Some key achievements include:

  • Spearheaded an organization of 35+ developers and QA (consultants and FTEs) to execute on multi-year roadmaps that expanded Kroger’s payment acceptance, resulting in over $100 million in new revenue opportunities.
  • Managed the development of an omnichannel payments platform that in-store and e-commerce properties used. This new platform reduced the PCI scope of Kroger applications, operational and support costs, and the onboarding time for clients.
  • Hardened Kroger’s fraud defenses by implementing fraud checks at various touch points in the customer journey, resulting in fraud mitigations of over $10 million per year.
  • Established standardized tools and processes, such as standardized CI/CD pipelines, to accelerate delivery and enable consistency across teams in the payment and fraud domains.

Advanced Software Engineer

2020 — 2022 | Cincinnati, OH

Backend Java software engineer who led two software engineering teams, provided architecture and technical guidance to the teams and stakeholders, and architected the next generation of Kroger’s digital payments and fraud platforms. Some key achievements were:

  • Architected and led the development of a new payment gateway that handled transactional integrity, enabled new use cases, and opened up a $1 billion revenue opportunity by supporting SNAP EBT.
  • Enhanced fraud protection by developing a “review” queue where Kroger agents can review flagged orders and determined if the order was legitimate. This reduced checkout friction while protecting Kroger.
