Pixi.js Game Developer (Game Math&Physics)

Web Programming — incorrectly specified categories?

1500 USD

We’re looking for an experienced Pixi.js Game Developer to help improve and polish an existing 2D game. The project already has a working codebase and detailed technical documentation, allowing you to focus on what matters most: refining gameplay mechanics, enhancing physics, improving game mathematics, and making the overall experience more responsive, engaging, and enjoyable.

The core gameplay is already implemented, so your primary responsibility will be optimizing and fine-tuning the systems that define how the game feels. We’re looking for someone who understands how small improvements in physics, balancing, and game logic can significantly improve the player experience. Attention to detail is essential, and we expect a high level of quality throughout the project.

This is the first step in a much larger roadmap. We are building our own game development company and are looking for a developer who can grow with the team. After successfully completing this project, you will have the opportunity to take ownership of future titles as a Lead Developer, with a full-time position, fixed compensation, and long-term partnership opportunities.

Our goal is to create original, high-quality games rather than simply release projects quickly. We value clean architecture, thoughtful implementation, strong technical skills, and people who genuinely enjoy building polished products. We are assembling a team of experienced developers who can work efficiently, maintain high standards, and contribute to multiple upcoming projects.

If you have strong experience with Pixi.js, a deep understanding of game physics and gameplay mathematics, and enjoy refining mechanics until they feel natural and satisfying, we’d love to hear from you.

When applying, please include your portfolio of completed game projects, links to released titles, and a brief description of your contribution to each project.

I can start immediately and complete the Pixi.js polish in 10 days for $1,500. Within 24 hours, I'll deliver a concise mechanics and physics audit with a prioritized tuning plan, then refine the update loop, deterministic physics, responsiveness, game math, and balance curves. I won't rewrite the architecture unless the documentation reveals a genuine blocker.

Hello,

I’m an experienced JavaScript game developer with strong expertise in Pixi.js and 2D game development. I have hands-on experience refining gameplay mechanics, optimizing game physics, balancing game math, and improving overall responsiveness to create a smooth and engaging player experience.

What I can contribute:

* Improve physics, collision, and movement systems
* Fine-tune gameplay balance and mathematical calculations
* Optimize performance while maintaining clean, maintainable code
* Work efficiently with an existing codebase and technical documentation
* Deliver polished, high-quality results with attention to detail

I appreciate your focus on quality and long-term collaboration. The opportunity to grow into a Lead Developer role is especially appealing, and I would be excited to contribute to both this project and future titles.

I can share relevant game projects and explain my specific contributions during our discussion.

I look forward to hearing from you.

Best regards,

Aleksandr M.

You need someone to take a working Pixi.js game and make it *feel* right — tightening physics constants, rebalancing progression curves, and eliminating the friction points that stop players from staying engaged.

My approach: first I audit the existing physics layer to identify where forces, velocities, or collision responses produce unnatural behavior and fix them with tuned parameters rather than rewrites. Second, I profile the game loop for frame-rate consistency — Pixi.js ticker drift and interpolation issues are the most common source of "sluggish" feel, and I'd lock that down. Third, I review the math behind scoring, difficulty scaling, or any RNG systems and adjust them so the difficulty curve feels intentional rather than arbitrary.

I work directly in your existing codebase, no architecture rewrites unless the docs point to a structural blocker.

Could you share the technical documentation and describe which specific mechanic currently feels the most off — physics response, balancing, or something else?
