I can jump right into your Unity WebGL project today to fix your bugs and clean up those monolithic scripts. As a developer fluent in C# and the Unity engine, I know exactly how to refactor messy, oversized scripts into clean, decoupled managers that are easy to maintain and scale. I am fully comfortable leveraging advanced AI development workflows to speed up the debugging process and optimize your code rapidly. I will deliver a stable, production-ready WebGL build that you can upload immediately for your MVP launch. Let's get these remaining blockers cleared out so your game can finally see daylight. I will systematically break down your heavy scripts into a modular, event-driven architecture, ensuring your frontend handles data cleanly. I have a strong understanding of full-stack environments, meaning I can ensure your C# frontend plays perfectly with your Go-lang backend, Cockroach DB, and Cloudflare R2 storage without causing network or save-state errors. I will also double-check that your active integrations like Xsolla payments, Spine animations, and mail webhooks remain unbroken during the refactoring process. Once the initial build is successfully deployed and running smoothly on the live server, I am completely available to stay on board for long-term support. I will assist you with incremental gameplay updates, quick server hot-fixes, and performance optimization advice to keep your WebGL memory footprint lightweight.

Hi there, Your Unity WebGL MVP is close, but the last stretch usually exposes the ugly stuff: brittle scripts, build settings, asset loading, and small WebGL-only bugs. I’ve worked on Unity/C# projects with WebGL builds, backend integrations, analytics, and release cleanup. I’d handle it in a practical order: - reproduce and fix the current bugs - split the worst monolithic scripts without changing behavior - make the WebGL build clean and repeatable - check Xsolla, analytics, R2 assets, mail flows, and backend calls where the bugs touch them - stay available after launch for hot-fixes and small updates Which bug currently blocks the WebGL MVP from being uploaded: build failure, runtime error, payment flow, or backend/API issue? I can start with the bug list and project structure, then push toward a launchable MVP build first before doing deeper cleanup. Thanks, Slavko

Getting a Unity WebGL project ready for release is often less about big changes and more about cleaning up the small issues that affect stability and performance. I can help you get this MVP into a solid, launch-ready state without overcomplicating the process. My approach would be to first identify and fix the existing bugs, then refactor the larger scripts into smaller, more maintainable components so future updates are easier to manage. I’ve worked with WebGL builds before, so I’m careful about performance, load times, and ensuring the build runs consistently across browsers. I’m also comfortable working with your broader stack, including backend integrations and third-party services. Where useful, I leverage AI tools to speed up debugging and refactoring, but always with manual control to keep the code clean and predictable. Before we proceed, I’d like to understand where the main pain points are right now. Are the issues mostly related to runtime bugs, build failures, or WebGL performance? And are there specific scripts or systems that you already know need restructuring? I’m happy to not only help you launch but also stay involved afterward for ongoing fixes and optimizations as your MVP evolves.

Hi! This is Jorge from IT GLOBAL SOLUTION LLC (FL, United States). I’ve delivered Unity WebGL 2D MVPs that were “almost there,” including WebGL-specific bug fixes and C# refactors to remove monolithic scripts. Your MVP path sounds right, especially the goal of a reproducible, upload-ready WebGL build. First, I’ll stabilize the WebGL target by reproducing each issue in a consistent environment, isolating root causes across input/timing, asset loading, WebGL memory/perf, UI event flow, and any JS interop, then patching with minimal surface area. In parallel, I’ll refactor oversized Unity scripts into smaller single-responsibility components (gameplay state, UI/controllers, input, persistence save/load hooks, analytics dispatch, and network/API client logic) while keeping public interfaces stable so existing scenes/prefabs don’t break. For build quality, I’ll enforce a clean WebGL pipeline with deterministic settings, asset/Addressables checks if used, stripping rules, correct build configuration, and an automated “build + smoke test” verification so you can upload immediately. On the backend, I’ll review the Go services for client integration and any Xsolla payment flow, verify Cockroach DB schema/indexes and idempotency for retries, and ensure ZohoMail and MailerLite integrations are robust (webhooks/queues if applicable). I’ll also align Unity Analytics so events fire reliably across WebGL sessions and confirm secure, failure-tolerant Cloudflare R2 usage.
