Progressive Jackpot Slot Game Build

I need a complete online slot game—front end for players and a full-featured back office so I can manage everything in one place. The game itself must be a classic slot experience with a standout progressive jackpot feature that grows in real time and pays automatically when it hits.

Core requirements
• Front-end slot game with polished graphics, sound, smooth spins, and responsive play on desktop and mobile
• Progressive jackpot logic that increments with each wager, stores safely in the database, and triggers a payout animation plus ledger entry when the win condition is met
• Secure account, balance, and transaction handling (preferred stack is open, but stability and security are non-negotiable)
• Admin panel (back office) where I can:
– create or edit game parameters (RTP, pay-table, bet limits)
– view live jackpot size, player bets, and history
– trigger manual bonuses or free credits
– export financial and player activity reports

I will choose a developer based on the depth of their proposal, so please attach a proposal proyek yang terperinci detailing technology stack, milestones, estimated timeline, and any similar work you have shipped. Links or demos to previous slot or real-money gaming projects are a plus.

Delivery includes full source code, build instructions, database schema, and short hand-over session to walk me through deployment and admin use.
