Enterprise Payment Microservices
2023–now
Payment services split along the boundaries that matter — gateway, payments, ledger, notifications — carrying millions of records a day.

What it did
The problem
Why it needed building
High-volume payment traffic needed dependable services and fast production fixes — millions of records a day flowing through gateway, payments, ledger, and notification paths, where downtime or backlog has direct financial impact.
The approach
How it works
Delivered .NET Core microservices with clear service boundaries, Redis-backed hot paths, and Docker-based deployment, plus the hotfixes and operational support that keep a high-throughput payments platform healthy under real load.

The trade-off
What it cost
Clear service boundaries cost cross-service consistency — transactions stay inside a single service and the ledger reconciles afterwards. That is more moving parts than a distributed transaction, but it degrades during a partial outage instead of deadlocking on one.
