Things I've built

Reorder (Walmart Business)

Built personalized reorder recommendations surfaced from past purchases by recency and frequency. The feature became the single largest revenue driver on the platform, correlating with an estimated 60% of total Walmart Business revenue. A high-leverage, low-friction win for repeat B2B purchasing at scale.

Spend Controls

Delivered a suite of B2B spending control features — Spend Analytics and Spend Limits — addressing a table-stakes need for business customers. Admins get a dashboard view of all organizational spending; configurable approval workflows enforce per-member caps for purchases above set limits. Purpose-built for larger enterprise buyers managing distributed purchasing.

CRM Integration (Marketo)

Connected the Walmart Business platform to Marketo to power personalized lifecycle marketing at scale. The integration became the engine behind 130% YoY membership growth and 111% YoY CRM-contributed revenue. Enabled evergreen email and push campaigns across a fast-growing B2B customer base.

Reporting Platform Modernization

Led a 4-year program to replace 7 legacy AppleCare reporting tools with a unified, role-tailored suite serving 65k contact-center managers and agents worldwide. Rebuilt data pipelines, resolved data-integrity issues, and cut data load frequencies by 60%+, delivering near real-time performance data. Raised user satisfaction from 69% to 87.5% over the program — and the platform stayed in production 5+ years post-launch.

Customizable Web & Mobile Dashboard

Drove design, development, and launch of a highly customizable performance dashboard and its back-end database systems for ~5k AppleCare senior and executive managers. Gave leadership self-serve, decision-grade contact-center data on web and mobile. Achieved 80.7% user satisfaction in the initial post-launch survey.

Identity for B2B (Walmart Business)

Defined and shipped a B2B-appropriate identity model distinct from Walmart's consumer platform — separating a business identity from the personal identities beneath it. Included 2FA and SSO to meet the security expectations of SMB, nonprofit, and government buyers. A foundational platform capability enabling everything built on top of it.
