High-Scale Contest Platform
National media contest engine with automated drawing logic, cron-driven workflows, and AI-assisted coupon validation. Tuned for spikes from broadcast and print campaigns.
01 — Problem
What was in the way.
A national-scale media campaign needed contest entry, validation and drawing to run reliably under broadcast-driven spikes — traffic could go from idle to hundreds of QPS within a minute of an on-air mention.
02 — Approach
How it was built.
- 01Laravel queues + Redis for write-heavy entry handling so the request path stayed fast under load.
- 02Cron-driven drawing and reconciliation jobs decoupled from user requests, with idempotent logic so retries are safe.
- 03AI-assisted coupon validation to cut manual review on edge cases.
03 — Impact
What changed afterwards.
- Held up through campaign-driven spikes without service degradation.
- Manual validation effort dropped sharply once the AI assist kicked in on suspicious entries.
