Svelte & PixiJS App Upgrade

I have a production web application written in Svelte and TypeScript that relies heavily on PixiJS for its canvas-based visuals. The core build is stable, but several areas now need polish and extension. I’m looking for a developer who is comfortable jumping into an existing codebase, identifying weak spots, and delivering incremental improvements without disrupting live traffic.

Here is the immediate scope:
• Refactor and tidy selected Svelte components so styling is easier to maintain and responsive across modern browsers.
• Improve the PixiJS scene code to keep frame rates high even as we add sprites and filters.
• Replace a handful of ad-hoc JavaScript helpers with clean, typed utilities.

You’ll be working in a repo that already uses Vite, ESLint, Prettier and GitHub Actions. I’ll grant access, walk you through the current architecture, and outline the first milestones; each will be small enough to review in a single pull request.

Acceptance criteria for every commit:
• No console errors or warnings.
• TypeScript passes strict mode.
• Lighthouse performance score holds steady or improves.

If you have shipped Svelte apps that leverage PixiJS before—and enjoy the mix of UI work, animation tuning and code hygiene—let’s get started.
