Verizon

Mobile Design System
Principal Engineer – Systems Architect

Problem

Design and engineering shipped inconsistently across mobile and desktop. Handoffs were slow, and brand and interaction patterns drifted across teams supporting a large internal workforce.

What I did

Architected a multi-platform mobile design system from a shadcn/ui and React Native reusables foundation, customized for brand and developer workflows. Aligned the desktop portfolio in parallel and established tokens, package boundaries, and monorepo release pipelines (Nx).

Results

  • Supported 7,000+ active internal users (field, retail, and leadership)
  • ~40% faster initial UI prototype builds after launch
  • Clearer design-to-code path and shared component contracts

Technologies

Takeaway

A design system succeeds when it's a product: versioned, documented, performant on real devices, and owned end-to-end — not a Figma dump.

Verizon

AI Feedback Sanitization Engine
Principal Engineer – Systems Architect

Problem

Customer and reseller comments needed safe, structured processing before downstream systems could use them.

What I did

Designed and implemented an AI-powered pipeline to sanitize sensitive content and extract structured signal from free-text feedback for downstream integration.

Results

  • Automated a manual, error-prone sanitization step
  • Improved readiness of feedback for integration workflows

Technologies

LLMsTypeScriptEnterprise integration

Takeaway

AI is most valuable behind clear contracts: inputs, redaction rules, and structured outputs teams can trust.

IBM

Quote-to-Cash Microservices
Senior Full Stack Developer

Problem

Core sales deal services needed reliability, modernization, and rapid response when security issues appeared.

What I did

Led full-stack work on Q2C deal microservices (Go, React, TypeScript); improved database performance and legacy paths; strengthened CI/CD and code quality practices shared across developer chapters.

Results

  • Production security hotfixes within 24 hours
  • More maintainable service boundaries
  • Stronger logging and secret-handling hygiene

Technologies

Takeaway

Enterprise trust is earned in the boring hours: logging hygiene, secret handling, and fast, disciplined incident response.

IBM Carbon Design System

Core Maintainer
View project

Problem

Global IBM and community sites needed a consistent, accessible Gatsby theme on Carbon — and a maintainable upgrade path.

What I did

Maintained theme upgrades (including major Gatsby moves), fixed bugs, and held the WCAG/a11y bar for widespread organizational use.

Results

  • Theme used across hundreds of portals
  • Major framework upgrades without sacrificing accessibility

Technologies

Takeaway

Open source maintenance is product ownership: compatibility, docs, and accessibility under real organizational load.
