The Bottleneck & Challenge
Legacy auction scripts suffered from bidding latency and race conditions during final countdown seconds, resulting in bid disputes and lost transaction volume.
The Engineered Solution
Constructed an event-driven bidding backend using WebSockets, Redis Pub/Sub, and PostgreSQL transactional locks to ensure strict zero-latency bid execution.
“Overall experience was very positive. They handled complex real-time bidding logic smoothly and adapted quickly to our changing platform requirements.”
