About

Product-minded engineer who sweats the details

I'm a JavaScript engineer with 5+ years building secure, accessible, and compliance-focused web applications for government and enterprise clients. I work fluently across the stack — React frontend, Node.js and middle-layer integrations, UX mockups, and accessibility — wherever a product needs me.

Lately I'm embedded with a U.S. govtech platform serving 800+ state and local agencies: contributing to the team's PHP → React modernization, building full-stack features for multi-tenant deployments, designing UX mockups for new compliance flows, shipping WCAG 2.1 AA accessibility, and supporting frontend / mobile-compatibility work across product releases. Before that I shipped React, React Native, and Next.js features for enterprise clients in retail, food delivery, and internal tools.

When something matters to a real user, it matters to me.

React Ecosystem

Production experience across React, React Native, Next.js, Redux Toolkit, and React Query — from component design to state management to data layers.

Fullstack Capability

Build end-to-end: React UI + Node.js / Express middle-layer connectors + REST APIs + PostgreSQL / MongoDB. Comfortable owning a feature from data layer to pixel.

UX Design & Mockups

Design complete user flow mockups for new features — covering edge cases, error states, and loading states — aligned with the existing design system.

Accessibility & WCAG

WCAG 2.1 AA remediation across enterprise portals — focus management, ARIA, keyboard navigation, screen reader support, and color contrast at scale.

Legacy Modernization

Migrating legacy PHP/HTML and jQuery codebases to modern React. Pragmatic and incremental — without halting feature development.

Mentorship & Cross-Functional

Active in agile ceremonies, technical interviews, and mentoring junior engineers. Comfortable bridging design, product, and engineering.
