We’re searching for a creative and technically strong JavaScript Developer who can build dynamic, interactive, and high-performance web features that feel modern, fast, and intuitive.
This role involves transforming UI/UX designs into real, functional experiences using Vanilla JavaScript, modern ES6+ features, DOM manipulation, Fetch API, async workflows, and component-based architecture (without relying heavily on libraries unless needed).
You’ll work on interactive components, dashboards, animations, mini tools, internal applications, and customer-facing pages. The ideal candidate understands not just code — but also user behaviour, accessibility, performance optimization, and clean architecture.
If you love turning ideas into highly responsive, elegant web interactions, this role is for you.
