We love vanilla JavaScript and work with cutting-edge technologies like TypeScript, Rollup.js, Cypress, and ESLint.

We are obsessed with Web Performance. See some of the improvements that we did https://engineering.wingify.com/posts/performance-improvements-in-vwo-smart-code/

Job Responsibilities:
