Jackpot & Coinflip Website Development

I’m building a fresh, security-minded gaming site that offers Jackpot and Coinflip modes and I want every core piece—from account creation to the last line of server logic—written cleanly and ready to scale.

Gameplay & real-time logic
• Steam OpenID is my preferred sign-in so players arrive with one click, their avatar and username already in place.
• Once inside, bets and animations run instantly through WebSockets; no polling, no page refreshes.
• Server-side code must own the provably-fair roll, manage countdown timers, select the winner, then atomically update balances before broadcasting results.

User balance system
Players need to deposit or withdraw skins / currency, see a running transaction history, and benefit from a bonus or reward system I can tweak later. Accuracy and double-entry style bookkeeping are critical.

Interface expectations
The entire site should keep a sleek dark theme and remain fully responsive. A live panel will highlight recent winners, total games played, and today’s top players while a separate page stores complete game history.

Admin & maintenance
An internal dashboard should let me:
• adjust or freeze balances,
• ban or unban users, and
• review every finished round with seed, hash, and payout details.

Acceptance criteria
1. Source code (API, WebSocket server, UI) delivered in a private repo with clear setup instructions.
2. End-to-end test demonstrating a full Jackpot and Coinflip round, starting from Steam login to winner payout.
3. OWASP-style security checklist showing how common exploits—CSRF, rate-limit abuse, item-duplication—are mitigated.
4. Deployment script (Docker or similar) that spins up the stack on a fresh VPS.

If you’ve shipped similar real-time gambling projects and can keep the codebase modular and documented, let’s talk timelines and milestones.
