Über Andrii
I am a Senior developer with 9+ years of production ReactJs experience and 11+ years of Web Development in total.
Right now I am a contractor / freelancer in Berlin, Germany. I am helping my clients to build robust solutions with focus on user experience. For some clients I have also builded sharable UI components (UI Library) that can be used across different projects using NPM registry.
I have been working with Redux for 5 years, also I am working right now with Apollo / GraphQL. I have been using TS for more than 6 years. For testing I am using Cypress.io for E2E and Jest for unit, visual regression, snapshot testing.
