We’re seeking a high-energy, detail-oriented JavaScript Developer to help us build a modern, interactive web platform with clean UI and seamless user experience. This project involves developing dynamic components, integrating APIs, improving page performance, and ensuring responsive design across all major screens.
You’ll work closely with our design team, backend developers, and QA testers to create features that look great and perform smoothly. We’re not hiring someone to write basic scripts — we want someone who understands user behavior, knows when to optimize, and can structure JavaScript code for long-term scalability.
You’ll be working on features like interactive dashboards, user flows, animations, dynamic forms, data visualization, and real-time content rendering. This role is perfect for developers who love turning Figma designs into pixel-perfect UI and know how to build components that feel “alive”.
This is a one-time project (6–10 weeks) with opportunities for long-term collaboration once we launch newer modules.
If you’re a creative problem-solver who enjoys building smooth, responsive, and engaging websites — we want to talk.
