I will create a web game on Node.js + React with WebGL rendering, state-machine logic, and a replay system. The backend will be built on an event-driven architecture with clear state transitions, storing states through Redis or in-memory with serialization for session replay; on the front end, Pixi.js or Three.js for WebGL. Question: what specific type of game is meant, slot mechanics, casual strategy, or something else, and is there documentation for the external API of the platform?

Hello!

I am Alex from the NC-1 development team. With over five years of experience, we specialize in high-performance e-commerce, complex ERP/CRM systems, and interactive web applications featuring game logic and WebGL visualization.

Project Team:

PM & QA – Ensuring platform compliance and rigorous mechanics testing.

Senior Architect – Designing state-driven logic and the Replay system.

Full-stack Devs – Building a NestJS computational backend and WebGL frontend.

UI/UX Designer – Creating high-performance dynamic interfaces.

Our Approach:
We will implement a clear separation between the computational backend (event processing and modifiers) and a high-performance WebGL frontend for smooth animations. The system is designed for stability, scalability, and precise session reproduction via a custom Replay module.

Estimate:

Budget: $23,065.

Timeline: 3.5 – 5 months.

Tech Stack: Node.js (NestJS), PostgreSQL/Redis, and Three.js (WebGL) for maximum cross-platform performance.

I have several ideas on how to optimize the architecture to launch an MVP faster while maintaining the potential for scaling. Let’s discuss how we can bring this project to life! Expand

Hello! I have carefully studied your requirements for the development of an interactive web application. I already have a working framework (prototype) that fully meets your specifications, allowing me to complete the project in a short time — in 5 days.

What I offer and what has already been implemented:

Authoritative Simulation: All logic (state-driven) is calculated on the server (Node.js/Fastify), which eliminates the possibility of data manipulation on the client side.

Deterministic Replay: The session recording system is based on seed + user intent stream, allowing for perfect game reproduction with minimal data storage.

High Performance: Rendering on PixiJS (WebGL) ensures stable 60–120 FPS even on mobile devices.

Telegram Integration: A ready base for verifying initData through HMAC SHA256 and working with the Telegram WebApp API.

Complex Architecture: Several modes have been implemented (Classic/Overdrive), a system of dynamic modifiers, and iterative state updates.

I am a programmer with experience in developing system software and game logic (Java, Luau, TypeScript). My approach is to first establish a stable base and data security, and then focus on the visual part.

I am ready to demonstrate the current base and discuss the integration of your API.

I understand that you need to develop an interactive web application with a client-server architecture for a web game. The task is not simple, as it will require the implementation of advanced game logic and integration with external APIs, which demands good architecture and deep knowledge in development.

I propose to develop a system with a clear separation of logic between the backend and frontend. On the server side, event processing and game state generation will be ensured, while on the client side, there will be a responsive interface with high performance. An important point will be the implementation of dynamic updating mechanics for elements and support for multiple game modes.

It is worth noting that there will be potential risks when integrating with APIs, as additional debugging work may be required. It is also necessary to clarify the technical limitations of the chosen platform. Please specify which external systems you want to integrate and what logic you need to implement in the game.

We can quickly discuss the details and move on to planning in the next step.
