I build accessible production web applications with React, TypeScript, Node.js, GraphQL, and AWS.

At Ergosign, I build and maintain production web applications with React, TypeScript, and JavaScript, creating reusable components and responsive user interfaces.

I also contribute across the stack with Node.js and TypeScript, working on business logic, validation, data transformation, APIs, and external-service integrations. I investigate and resolve production issues spanning GraphQL APIs, AWS services, and third-party systems.

I took technical ownership of web accessibility while preparing a platform for an external assessment, translating BITV and WCAG requirements into actionable development work. Through code reviews, developer onboarding, and collaboration with engineering, design, project management, and clients, I helped the platform complete an independent BITV 2.0 / EN 301 549 accessibility assessment.

Before software engineering, I worked in education and educational technology, supporting bilingual learning, Maker Lab projects, science fairs, and volunteer physics education initiatives.
