I need a complete front-end and back-end build that mirrors the look and feel of Velki123Live.com while working flawlessly on desktop, tablet, and mobile. The project targets sports betting and live-casino features in equal measure, so every screen, widget, and interaction should feel consistent across both verticals. Core requirements • UI/UX: pixel-perfect replication of Velki123Live.com, fully responsive. • Multi-tier admin: Admin → Sub-Admin → Super Agent → Master Agent → End User, each with hierarchical controls, profit/loss reports, and real-time user activity tracking. • Token API: secure token-based authentication and session management, backed by Redis caching for speed and scalability. • Sportsbook: real-time markets and odds via Betfair API. • Live Casino: Evolution Gaming iframe integration. • Wallet: live balance, bet history, and withdrawals, all reflected instantly across the platform. • Source code: full, well-documented delivery at project hand-off. I’ll shortlist on the strength of your detailed proposal—please outline architecture, tech stack, security measures, milestones, and any similar builds you have completed.
