Fintech Industry Case Study
Rebuilding a Core Payments Engine with Zero Live Downtime. How we decoupled a slow, legacy system into fast, independent services to restore engineering velocity. Node.js PostgreSQL Docker AWS Redis +more
Brightpath was processing millions in transactions through an old software monolith. The code was tangled. A tiny bug in the billing UI could crash the entire checkout line. Adding new payment methods took months of risky, stressful work.
Brightpath was processing payments through a five-year-old monolith. It was slow, fragile, and blocking every new feature. We rebuilt the core payments layer as a set of independent services — without touching live transactions.
Our Solution
We didn't throw everything away at once. Instead, we isolated the payments engine step-by-step. We built standalone microservices to manage transactions, routing traffic over gradually while checking for errors in real time.

Real problems solved. Real results delivered.
We don't just talk about building great backends. Here's proof..
97%
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%.
60%
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.
5000+
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.
