Staff engineer building tools users adopt by default
Staff software engineer building internal tools that become the default workflow for the people who rely on them. I’ve shipped production systems for Apple, Google, and major consumer brands, including an Apple workflow accessed by 60+ production users across hardware engineering and factory-floor operations to process 1–4 TB datasets with peaks near 20 TB.
Enterprise Projects
Mission-critical applications built for Apple, Google, and Fortune 500 companies using React, TypeScript, and modern web technologies
Hardware Test Data Platform
Owned end-to-end delivery of confidential internal tooling for Apple's hardware engineering organization. Sole architect of the Next.js/React frontend with substantive contributions to the Flask API gateway and Kubernetes-scheduled sequencer service. Replaced error-prone parameter entry and deep Box.com folder navigation with a guided retrieval workflow that validates real parameter combinations and makes pipeline setup take about 30 seconds for simple cases and a few minutes for complex ones. Added an in-app media browser with search so users can view images, CSV files, and text files without switching between external systems. Added pipeline observability for downloaded and pending days, excluded files, data volume, and total, passed, and failed tests. The workflow has been accessed by 60+ production users across Apple hardware engineering and factory-floor operations while processing 1–4 TB datasets with peaks near 20 TB. Includes a Storybook-driven documentation pipeline that keeps end-user docs in sync with the shipped UI.
AI-Powered Healthcare Platform
Architected and delivered a sophisticated healthcare platform leveraging AI large language models to reduce operational costs and deliver measurable value to enterprise customers. Developed comprehensive web dashboard for subscription management, Chrome extension for seamless website integration, and implemented enterprise-grade Auth0 authentication across all platform components.
Silicon Design Collaboration Platform
Designed and prototyped Fuse Manager, an innovative version control system for silicon chip design specifications at Google. Created comprehensive proof-of-concepts and wireframes that guided architectural decisions for a platform enabling seamless collaboration across 20+ hardware engineering teams. Successfully transitioned prototypes to production-ready application using Angular and Google's internal toolchain.
Context-Agnostic Component Library
Architected a context-agnostic component library serving Williams Sonoma's brand portfolio (Pottery Barn, West Elm, Mark and Graham). Components adapt to each brand's design language through CSS variables while maintaining consistent functionality. Implemented configurable behaviors allowing customization of component orientation, initial states, and interaction patterns while preserving accessibility and performance standards.
