Sr. Front-End Developer - FT Freelance - Worldwide

A bit about us: We are the team behind Gamblit. While we successfully got it to market, building this project as "amateur" developers and vibe-coding a lot of it lead to a laggy frontend and a codebase that is hard to scale.

Now, we are launching a brand-new platform under a new name. We want every game (take a look at our website's Original Games and their animations) and all the features on our website super optimized from day one for the user. We have a design team working on the Figma of our platform which you will have to convert into pixel-perfect production ready code with clean, optimized animations.

Role Overview

Join our team as a Senior Frontend Developer to help us build our new gambling platform.

Responsibilities

• Convert Figma design to pixel-perfect production ready code.
• Enhance the user interface with smooth & optimized animation for our games.
• Ensure the frontend code is clean & optimized for long-term performance and scalability.
• Implement real-time server communication using Socket.io.
• Collaborate closely with backend developers to integrate frontend functionalities.
• Conduct thorough testing to ensure cross-browser compatibility and responsiveness across all screen sizes & make sure the website & it's animations are optimized to run on devices with low capabilities (example: low-end mobile phones)

Required Skills

• Deep expertise in writing modular, clean & optimized Next.js code.
• Knowledge of Socket.io for real-time server communication.
• Expertise in Framer Motion, GSAP, CSS/Canvas animations (we are looking for someone who understands spring physics, easing functions, and maintaining a consistent 60 FPS under load)
• The ability to translate complex Figma designs into responsive, production-ready Tailwind CSS code with extreme attention to detail in spacing, typography, and motion.
• Familiarity with version control systems like Git.

Nice to Have

• Experience in developing for the gambling or gaming industry.
• Understanding of performance optimization techniques in web development.
• Strong eye for design (you can spot when a padding is 2px off or when an animation curve feels "clunky" rather than "fluid," and you know how to fix it without being told)

We don't care about a generic CV as much as we care about what you’ve actually shipped!

Please make sure to share:

• Live projects where you handled complex, real-time data (Socket.io).
• Examples of high-end animations you are proud of.
• A GitHub repo or code snippet that demonstrates your approach to Clean Code
