Good day!
We are ready to implement a custom iGaming platform with fully server-side logic, managed RTP, and a scalable architecture for 5,000+ online users.
We understand the key requirements:
- RNG and all mathematics exclusively on the server (crypto-based, seed + nonce)
- Ledger approach (balance = sum of transactions)
- Modular games (for example, Crash via WebSocket)
- Admin panel for managing RTP, volatility, payout JSON
- White-label architecture
- Protection against replay/race/exploit
The IcornA team covers backend, DevOps, and security, providing a comprehensive architecture, financial logic, load testing, and deployment.
Additionally, the team includes mathematicians who can accurately calculate game mechanics to retain players and motivate them to continue playing.
Estimated budget - from $25,000. We are ready to discuss details and propose a phased implementation plan.
Sincerely Expand

Hello,

Your project requires building a fully server-side gaming engine with controlled mathematics, ledger-based finance logic, WebSocket crash mechanics, and white-label scalability. This is not just a website — it is a high-load financial system with gaming mathematics and security-critical architecture.

I have experience building scalable backend systems using Node.js / PostgreSQL / Redis with queue-based async processing and Dockerized deployments. I understand ledger-based balance systems, provably fair RNG (server seed + nonce), and secure WebSocket architectures.

How I would approach your project:

• Modular backend architecture (each game isolated as a module)
• Server-side RNG using cryptographically secure generation
• Ledger-based financial core (transactions-only balance model)
• Crash engine via WebSocket with pre-generated crash points
• RTP / volatility system controlled via admin panel
• JSON-based payout tables
• Anti-exploit protections (race condition, replay attack, cap limits)
• Admin dashboard with game management, bonuses, withdrawals
• White-label ready architecture (brand-based configuration layer)
• Dockerized deployment with documentation Expand

Good evening, I was developing a crypto casino. Stack - Docker, Symfony, React. Here is the link - https://luckygames.io. Everything is custom written.

Budget: 11500 EUR Deadline: 60 days

Hello! Thank you for the detailed project brief — based on the description, this is a **large custom iGaming platform** with serious requirements for mathematics, security, scalability, and administration. I am ready to take on this project and build it as a production system, not a prototype.

**Work and Payment Format**
I propose a phased scheme: **25% of the result = 25% of the payment** (milestones). Each phase is delivered, accepted by you, and only after that does the next one begin. All development is exclusively on your server, with your access (SSH/DB/repo), all code and architecture belong to you.

**How I will implement the project (brief and to the point)**

1. **Architecture and Foundation (Phase 1)**

* Docker-based deployment, clear microservice structure.
* PostgreSQL + Redis, queues, and async processing.
* Ledger model for finances (balance = sum of transactions).
* Basic admin panel: users, deposits, withdrawals, metrics.

2. **Game Core and WebSocket (Phase 2)**

* Server-side Crash engine (pre-generation of crash-point, server-side cashout).
* WebSocket real-time with scaling for 5,000+ online.
* Strict limits (max bet / max payout / period cap) and round logs.

3. **Mini-games + Managed Mathematics (Phase 3)**

* All games are separate modules.
* All mathematics and RNG **only on the server** (crypto-resistant RNG, server seed + nonce).
* RTP 80–99.99%, volatility, payout tables in JSON — all managed from the admin panel.

4. **Bonuses, White-label, and Production Hardening (Phase 4)**

* First deposit, reload, cashback/rakeback, separate bonus balance + wagering.
* White-label: one engine → multiple brands (domain, design, settings).
* Comprehensive documentation, database structure, and deployment instructions.

**Load and Security (Important Block)**
I will conduct:

* load testing (HTTP + WebSocket), stress tests for DB/Redis/queues;
* optimization for traffic peaks and degradation without crashes;
* setup of anti-abuse measures, protection against replay/race/packet abuse, rate limiting, and service isolation;
* centralized logging and monitoring.

Additionally, I will perform a **vulnerability assessment**: checking business logic, financial flows, betting manipulations, replay requests, timing attacks, and potential exploits.

For network DDoS risks, we will properly configure external protection (e.g., Cloudflare/WAF + L4 hosting protection) and test failure and recovery scenarios.

If this approach works for you — I can start with Phase 1 immediately after receiving access and UI design. I am ready to discuss the tech stack (Node/Go/Python) and final details. Expand

Hello!
My name is Alexey, and I represent the NC-1 development team. We have been creating websites, mobile applications, online stores, ERP/CRM systems, gambling projects, and other products for over five years. We have already developed similar platforms - Ne.casino, valor.bet, and Phoenix - these are gambling projects with cryptocurrency integration.
I propose our team for development:
Senior Backend Developer (Team Lead) - architect, mathematics, finance, sockets, security.
Middle Frontend Developer - layout, game integration, working with Canvas/WebGL (for Crash/Plinko animations), admin panel.
I recommend the stack: Backend in Golang (or Node.js) with PostgreSQL and Redis databases for implementing financial ledger and high load, Frontend in React or Vue using WebSockets for communication and PixiJS for smooth game animations.
