Senior UI Developer delivering high-performance React experiences through microfrontends and rigorous testing.
EstoniaWhat I'm looking for
I’m a Dynamic Senior UI Developer with over 10 years of experience specializing in frontend technologies such as React, Next.js, TypeScript, and Redux. I’m known for optimizing codebases and translating complex product needs into maintainable UI systems.
In my current role, I engineered a React/Next.js frontend using styled components, then revamped the existing codebase for enhanced performance and optimization. I also instituted a Microfrontend architecture to improve collaboration across cross-functional teams.
I focus heavily on reliability and quality: I authored unit tests and end-to-end tests using Jest, Cypress, and React Testing Library. I’ve also implemented integrations like Twilio phone and SMS services to support real-world communication flows.
Earlier, I architected UI libraries and components with React, MUI, TypeScript, and Redux, leveraging GraphQL queries and mutations via Apollo GraphQL Client. I’ve supported real-time functionality with socket.io and driven visibility through Amplitude and logging with Sentry.
