About the Role

We’re looking for a Full Stack Developer who deeply cares about how things look, feel, and flow. Someone who writes elegant code and designs beautiful, functional experiences that users love.

You’ll work at the intersection of design and engineering, turning ideas and prototypes into smooth, high-performing applications built on React and Node.js. This role suits developers who think in pixels, obsess over transitions, and genuinely want every click and animation to feel just right.

• Maintain high code quality through clean architecture, testing, and peer reviews.

You’ll Fit Right In If You

• Love crafting beautiful, consistent, and intuitive interfaces.
• Notice when a button is off by a few pixels and care enough to fix it.
• Balance creativity with engineering discipline.
• Enjoy solving real user problems with thoughtful design and seamless performance.
