- Sole senior contributor on a large-scale AEM platform: PIM integration, product/parts filtering, a Jackrabbit Oak search-index migration, dispatcher/release engineering, and localization.
- Contributed high-impact fixes to a shared platform-core library used across a multi-brand estate — content-activation workflows, thread-safety fixes in resource-resolver handling, and dispatcher cache/HTTP client refactoring.

- Built a KYC/compliance intake pipeline processing structured submissions against onboarding requirements.
- Hired and led an outsourced team of 9 engineers who rebuilt the platform in PHP, integrating Stripe, Firebase, and GCP.
