What I'm looking for

I seek a role where I can own frontend features and systems, work across frontend/backend boundaries, improve testing and CI/CD, and contribute to scalable, maintainable architectures in a collaborative team.

I am a senior frontend engineer with strong full-stack capabilities, focused on building and delivering web applications using React, TypeScript, GraphQL, and modern frontend architectures. I take ownership of features and systems, maintain high code quality, and apply effective testing practices in collaborative engineering environments.

Throughout my career I have implemented monorepos, improved frontend testing strategies, and migrated backend systems to more reliable databases while ensuring frontend-backend consistency. I have designed CI/CD pipelines and infrastructure with GitHub Actions and Pulumi, and built event-driven solutions on AWS using Lambda, SQS, S3, and SES.

I bring hands-on experience across frontend and backend stacks — including Node.js, Express, PostgreSQL, MySQL, MongoDB, Storybook, Jest, and Cypress — and consistently contribute to technical planning, estimations, and maintainability improvements to deliver scalable, reliable products.
