Type: custom iGaming web platform (crash + mini-games)
1. Work format
• All development only on our server
• Access provided (SSH / DB / repo)
• All code and architecture belong to the client
• No Firebase, no-code, client-side logic
2. Goal
To build a server-side gaming platform that can handle traffic, with:
• controlled mathematics (RTP / House Edge)
• a full admin panel
• scalability and white-label options
3. MVP: games (10 pcs)
Crash (1 engine, different UIs):
1. Aviator-style
2. Speed Crash
3. Chicken Road Crash
4. Space Monkey Crash
Mini-games:
5. Plinko
6. Dice
7. CoinFlip
8. Mines
9. Tower Rush
10. Wheel (mini-roulette)
4. Key architectural requirements
• All mathematics and RNG only on the server
• Client — only visual
• All games — separate modules
• Crash via WebSocket
• Scalability for 5,000+ online
Stack:
• Backend (Node / Go / Python — not critical)
• PostgreSQL + Redis
• Queues / async processing
• Docker / proper deployment
5. Finances
• Ledger approach (balance = sum of transactions)
• Types of operations: deposit / bet / win / bonus / withdraw
• Balance is never stored as a single number
6. Gaming mathematics
• RTP: 80.00 – 99.99%, adjustable in the admin panel
• House Edge is calculated automatically
• Volatility: low / mid / high
• Payout tables — JSON, editable
Crash:
• crash-point is generated in advance
• cashout is recorded by the server
• limits: max bet / max payout / period cap
7. Admin panel
• Dashboard (users, deposits, profit, pending)
• Game management:
• RTP slider
• volatility
• payout JSON
• Users
• Finances
• Promo codes
• Withdrawals (manual approve/reject)
8. Security
• Cryptographically secure RNG (not Math.random)
• server seed + nonce
• Anti-exploit:
• win limits
• protection against replay / race / packet abuse
• Log of each round (for disputes)
9. Bonuses (MVP)
• First deposit bonus
• Reload bonus
• Cashback / rakeback
• Separate bonus balance
• Wagering, limits, logging
• Management through the admin panel
10. White Label
• One engine → multiple brands
• Brand = domain + design + settings
• UI separated from logic
• Architecture ready for cloning
11. What the client provides
• Design / UI
• Content
• Server
12. What the developer must deliver
• Source code
• Documentation
• Docker / instructions
• Database structure
13. Acceptance criteria
• All 10 games work
• RTP actually affects the mathematics
• Balances match according to the ledger
• Admin panel manages everything
• Nothing crashes under load

265 1 day115 USDHello!
I have experience in developing complex server systems, including web platforms with game mechanics mathematics, balance through a ledger approach, and socket communication (Node.js / Python / Redis / PostgreSQL / Docker). I am ready to create a custom iGaming platform with separate modules for each game, a crypto-resistant RNG, an RTP/volatility settings system, and a full admin panel.
I will provide a scalable architecture with async queues, WebSocket processing for Crash games, automatic balance auditing, and logging of each round. I have experience in developing financial accounting models (deposits, bonuses, cashback, wallet), setting up security and billing mechanisms.
All code will be deployed and tested directly on your server, with full rights transfer to the client, documentation, and Docker structure. I am ready to discuss the details of the architecture and timelines in private messages to propose the optimal stack and implementation plan for the MVP.

The technical specifications are completely clear, server-driven iGaming with crash and mini-games is my specialty.
I have done:
• crash via WebSocket (pre-generated outcomes),
• mini-games with controlled RTP / volatility,
• ledger finances (deposit / bet / win / bonus),
• crypto-secure RNG (seed + nonce),
• anti-exploit + round logging,
… • white-label architectures under load.
All mathematics and RNG are only on the server, the client = visual.
Each game is a separate module, ready for scaling.
MVP (10 games):
• timeline: ~ 4 weeks
• budget: ~ 3k€
I work on your server, the code is completely yours.
I am ready for long-term support and development.
I am ready to discuss the architecture.

- 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.

941 3 0 150 days6924 USDHello,
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

60 days13 272 USD
264 60 days13 272 USDHello! 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.

396 80 days17 773 USDHello!
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.
Our cases: https://1drv.ms/b/c/b7a0d31a9dae1bc5/IQCpK38gmEvWT6F_Cso40Li-AXAKkSs-J67mCwll-C732pw?e=v4VVF5
