About

Professional summary

I am a Senior Front-End Engineer with over seven years of experience building production web applications with React and TypeScript. I also have three years of experience contributing to full-stack product features, including backend services and data-driven platform capabilities.

I specialize in creating scalable, accessible, and maintainable user interfaces. My front-end expertise includes React, Next.js, JavaScript, TypeScript, HTML, CSS, SASS, design systems, and web accessibility.

I have hands-on backend experience with Node.js, TypeScript, PostgreSQL, API endpoint development, email queue refactoring, custom logging, and Twilio webhook integrations. I have supported telemedicine products operating in regulated healthcare environments.

I am experienced with OAuth and JWT authentication flows, automated testing, CI/CD practices, and Agile delivery. I use Jest, Vitest, React Testing Library, Playwright, and TDD practices to help ensure software quality.

I have worked with AWS infrastructure including EC2, S3, and ECS, as well as Terraform, Docker, and Kubernetes. I also use AI-assisted development, LLMs, prompt engineering, and workflow automation to accelerate technical research, refactoring, and prototyping.
