The Challenge
Shotcall, an American startup, came to CodeX with a bold vision: create a single platform where creators could build audiences, sell merchandise, offer digital downloads, auction exclusive items, and engage fans through social features and real-time chat. They needed an MVP in 4 months to secure Series A funding.
Our Approach
Phase 1: Architecture & Design (Weeks 1-3)
Intensive discovery sprint mapping every user journey. Mobile-first UI designed to feel familiar (Instagram + Shopify) with premium creator storefronts. Modular monolith architecture for fast shipping without tech debt.
Phase 2: Core Platform (Weeks 4-10)
Social Engine — Feed, profiles, follows, likes, comments with fan-out-on-write pattern for instant load times.
Commerce Engine — Product catalog, cart, checkout via Stripe Connect Express with platform commission.
Auction System — Real-time bidding with Redis state machine, optimistic concurrency control, proxy bidding, snipe protection, and WebSocket bid broadcasts.
Chat System — WebSocket DMs and group chats with persistence, read receipts, and typing indicators.
Phase 3: Creator Tools (Weeks 11-14)
Analytics dashboard, store customizer, content scheduler, and payout dashboard with Stripe Connect Express integration.
Phase 4: Launch (Weeks 15-16)
Load testing, security audit, and onboarding 500 beta creators.
Key Technical Decisions
- React + TypeScript — Type safety caught hundreds of potential bugs
- Redux with Optimistic Updates — Instant UI feel even on slow connections
- Stripe Connect Express — Handled KYC, international payouts, tax reporting
- Redis — Atomic operations prevented auction race conditions
