Design & Build UI: Work with Flutter and Next.js to create user-friendly, responsive, and visually appealing interfaces that flow intuitively from one feature to the next.

Prototype & Iterate: Help us move fast by building prototypes for new features, gathering feedback, and refining based on real user input.

Optimize for Performance: Ensure that our front-end performs seamlessly across mobile and desktop, focusing on speed and smooth interactions.

Code with Care: Write clean, maintainable code and keep an eye on best practices, from performance to accessibility, so DoublOne runs beautifully for every user.

Proficiency in Flutter & Next.js: You know your way around these frameworks, and you’re excited to use them to craft cohesive, cross-platform experiences.

Eye for Design: You’re comfortable turning a designer’s vision into reality, with a good grasp of UI/UX principles and a knack for what looks and feels right.

Problem-Solver at Heart: Whether it’s fixing a bug or figuring out the best way to implement a new feature, you love a good challenge and approach it with creativity.

Eager to Learn & Grow: You’re passionate about trying new things, whether it’s testing a new front-end technique or understanding user feedback, and you’re ready to expand your skillset.

Good Communicator: You’re comfortable sharing your thoughts and ideas, whether in code reviews or brainstorming sessions, and you listen actively to team feedback.
