Fintech Industry Case Study
Fixing a Broken Checkout Flow to Unblock $2M in New Sales. How we replaced an unstable payment route with a resilient, queue-backed processing gateway. Node.js Redis BullMQ PostgreSQL Stripe API +more
Fintza was losing nearly a third of its revenue right at the finish line. Their payment provider timed out whenever too many users checked out at once. Transactions simply dropped, leaving customers confused and support teams overwhelmed.
Fintza's checkout setup was dropping 30% of sales due to server timeout errors. We engineered a new payment API with resilient retry patterns and background queues, pushing transaction success up to 97%.
Our Solution
We built a dedicated background payment layer. We added smart database queues and automatic retry logic. If the core payment processor lags, our backend safely holds the request and updates the order the moment the path clears.

Safely processed over $2M in user transactions during the first quarter post-launch.

Patient profiles were scattered across three different internal software silos, slowing down daily operations. We built a single data access gateway that unifies records onto one screen in under two seconds.

Plurial's old school database routinely crashed under heavy load during student registration weeks. We built an event-driven registration engine that processed 5,000 sign-ups with zero lag.
