What I'm looking for

I am seeking frontend roles where I can build user-centric SaaS features, collaborate cross-functionally, and grow into technical leadership while delivering high-quality, maintainable interfaces.

I am a Senior Frontend Developer with over five years of experience building responsive, user-centric web applications using modern frameworks and libraries. I excel at translating complex requirements into seamless user experiences and delivering production-quality features for SaaS and enterprise platforms.

At Act-On Software I developed and enhanced an enterprise email marketing automation platform, creating reusable components, a robust email template editor with content validation and Litmus integration, dynamic content blocks, and test/send workflows while collaborating closely with backend and QA teams.

I am proficient in JavaScript/TypeScript, React/Next.js, state management, GraphQL/Apollo, testing with Jest/Cypress/React Testing Library, and styling with MUI/Tailwind/SASS. I focus on accessibility, performance, and maintainable code, and I enjoy working cross-functionally to ship impactful products.
