Verified Production Metrics
Problem Statement
Pakistani wedding marquees process millions of PKR per event during high season, yet venue managers relied on fragile physical registers, leading to devastating double-bookings, delayed vendor payments, and manual catering cost miscalculations.
Architectural Solution
Built a multi-tenant Next.js application with atomic database slot-locking, instant per-head catering formulas tailored to traditional cuisine, and an automated milestone ledger that sends payment reminders directly to banquet clients.
Critical Technical Decisions
Atomic PostgreSQL Transaction Locks
During peak wedding months (November–February), venue managers simultaneously field inquiries for the same auspicious dates. Row-level locks prevent conflicting reservations before payment verification.
Dynamic Per-Head Ingredient Calculation
Instead of fixed menu costs, catering formulas automatically calculate raw mutton, chicken, and basmati rice tonnage based on live market pricing and headcount tiers.
Zero-Latency Client Optimistic Updates
Ensured floor managers using smartphones inside noisy banquet halls experience immediate UI responsiveness when approving hall setup milestones.
